if point p is 3/8 of the distance from a to b, then point p partitions the directed line segment into what ratio from a to b? a. 3:11 b. 8:11 c. 3:5 d. 5:3
Answer:
b
Step-by-step explanation:
Final answer:
Point P divides the distance from A to B into a ratio of 3:5, with P being 3/8 of the way from A to B. The correct option is c.
Explanation:
If point P is 3/8 of the distance from A to B, we can understand this situation by imagining the entire distance from A to B as being divided into 8 equal parts, and point P lies at the end of the third part when moving from A to B. Since P is 3 parts away from A, it leaves the remaining 5 parts to reach B. This sets up a partition of the segment into two parts: one from A to P and the other from P to B. The ratio of these distances is the number of parts from A to P to the number of parts from P to B. Therefore, the ratio of AP to PB is 3:5. Option c is accurate.

The measure of one of the angles formed by two parallel lines and a transversal is 45°. Is it possible for the measure of any of the other seven angles to be equal to 55°? Explain.
Answer: No
Step-by-step explanation:
Three of the other angles are 45°. The other four are 180° - 45°, which is not 55°. At the intersection of two lines, opposite angles are equal and adjacent angles are complementary, so two adjacent angles add to 180°. Adding a parallel line gives four more angles identical to the first four.

Answer:
-16 sqrt(3) +16i
Step-by-step explanation:
z = 2 cis (pi/6)
z^5 = 2^5 cis (5*pi/6)
z^5 = 32 cis (5pi/6)
z^5 = 32 cos (5pi/6) + 32 i sin (5pi/6)
= 32 * (-sqrt(3)/2) + 32i (1/2)
= -16 sqrt(3) +16i
What is the Value of x+y ? PLZ Help ASAP
Answer:
x + y = 60
Step-by-step explanation:
In the given figure, we have two lines that intersect each other at one point.
Therefore, the opposite angles are equal to each other and we can write them in the form of an equation as:
2y - 5 = 95 --- (1)
3x + 55 = 85 --- (2)
Now solving each of the equations to find the value of x and y.
For y:
2y - 5 = 95
2y = 95 + 5
2y = 100
y = 50
For x:
3x + 55 = 85
3x = 85 -55
3x = 30
x = 10
Therefore, x + y = 10 + 50 = 60.
Question: Which of the following represents the equation of a line that is parallel to the line r shown in the graph?
Answer:
B
Step-by-step explanation:
• Parallel lines have equal slopes
calculate the slope m of the given line using the gradient formula and compare to the slope of the equations given
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 1, - 1) and (x₂, y₂ ) = (1,1) ← 2 points on the line
m = [tex]\frac{1+1}{1+1}[/tex] = 1 ← slope of graph
consider the slope of the given equations
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
(A)
y = 2x + 1 has slope = 2 → not parallel
(B)
x - y = - 3 ( subtract x from both sides )
- y = - x - 3 ( multiply through by - 1 )
y = x + 3 with slope = 1 → thus parallel to graph
(C)
x + y = 2 ( subtract x from both sides )
y = - x + 2 with slope = - 1 → not parallel
(D)
y = - x + 1 with slope = - 1 → not parallel
An equation of a line that is parallel to the line r shown in the graph include the following: B. x - y = -3.
How to determine an equation of this line?In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
x and y represent the data points.m represent the slope.First of all, we would determine the slope for this line by using these points (1, 1) and (0, 0);
[tex]Slope(m)=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope (m) = (0 - 1)/(0 - 1)
Slope (m) = 1
For the line to be parallel to the line r, it must have the same slope as line r. At data point (0, 0) and a slope of 1, an equation for this line can be calculated by using the point-slope form as follows:
[tex]y - y_1 = m(x - x_1)[/tex]
y - 0 = 1(x - 0)
y = x
Based on the answer options, we have;
y = 2x + 1 ⇒ slope is 2 (not parallel).
x - y = -3
y = x + 3 ⇒ slope is 1 (parallel).

a. -13.5 -20.25
b. -13.5 20.25
c. 6 4
d. 13.5 20.25
Answer: D
Answer:
d. 13.5, 20.25
Step-by-step explanation:
An exponential function is monotonic and does not change sign. On this basis alone, the first three choices can be eliminated.
The common ratio is 6/4 = 3/2.
The term in the sequence after 9 is 9·(3/2) = 27/2 = 13.5.
The term in the sequence after 27/2 is (27/2)·(3/2) = 81/4 = 20.25.
Final answer:
The missing values for the exponential function table with an increasing common factor of 1.5 are 13.5 for x=1 and 20.25 for x=2, making the correct answer Option D.
Explanation:
The student's question pertains to finding the missing values for the exponential function represented by the table with given x and y values. Given the nature of an exponential function, we expect that as x increases by 1, the value of y is multiplied by the same factor each time. We can observe this behavior in the initial y-values: 4, 6, and 9. To find this constant multiplier, we can divide 6 by 4 and 9 by 6, which both give us 1.5. This constant factor, which we'll call base of the exponential function, indicates that for every increase of 1 in x, the value of y is multiplied by 1.5.
To find the missing y-values for x=1 and x=2, we just continue multiplying by the base 1.5. Thus, when x=1:
y = 9 × 1.5 = 13.5
When x=2:
y = 13.5 × 1.5 = 20.25
Hence, the completed table should read as follows:
x=-2, y=4
x=-1, y=6
x=0, y=9
x=1, y=13.5
x=2, y=20.25
The correct answer is therefore Option D: 13.5, 20.25.

Which sequence matches the recursive formula? an=2an-1+5, where a1=5. A) 5,10,15,20 B) 5,15,35,75. C)5,15,25,35. D) 5,20,35,40
The recursive formula
[tex] a_n = 2a_{n-1}+5 [/tex]
means that, to compute the next value, you have to double the previous one and then add 5.
So, we start with 5. To get the second term, we double it and add five, so we have
[tex] a_2 = 2\cdot 5+5 = 10+5 = 15 [/tex]
Next, we will double 15 and add 5:
[tex] a_3 = 2\cdot 15 + 5 = 30+5 = 35 [/tex]
So, the answer is B, because it's the only option starting with 5,15,35.
Just to check, let's compute the last step:
[tex] a_4 = 2\cdot 35 + 5 = 70+5 = 75 [/tex]
Which confirms option B

i need help on finding the orthocenter of a triangle, i got the x right, x=6 but I got the Y value wrong, it's supposed to be y=4 but i got y=8 as my answer. the question is find the coordinates of the orthocenter of Triangle ABC with vertices A(2,6), B(8,6), and C(6,2). what i did to find the Y value was find the slope of BC then use that value and the coordinates of A and substituted them into an equation y-6=1/2(x-2), i solved it and got y = 1/2x+5. i then substituted my x value that i previously found into it to find Y , y=1/2(6)+5 . i got 8 as the Y value but it's wrong, can someone tell me what i missed?
Answer:
See the attached
Step-by-step explanation:
When in doubt, draw a diagram.
The orthocenter of this acute triangle will be within its bounds. That should tell you right away that the y-coordinate of it will not be 8, but must be between 2 and 6.
The line perpendicular to BC through A must have a y-intercept greater than the y-coordinate of A, so cannot be 5. Whatever it is, the y-coordinate of the orthocenter will be less, so again, your answer fails the reasonableness test.
The perpendicular line to BC through A is ...
... y = (-1/2)(x -2) +6 = -x/2 +7 . . . . . . looks like you had a sign error in (-1/2)(-2)
The intersection of that line and x=6 is ...
... y = -6/2 +7 = 4

Jose and Jenna competed in a bike race. After 30 minutes, Jose had finished 2/3 of the race and Jenna had finished 7/12 of the race. Who had finished more of the race?
Final answer:
After converting their completion fractions to decimal form, Jose finished more of the race than Jenna after 30 minutes, with Jose at 2/3 (approximately 0.6667) and Jenna at 7/12 (approximately 0.5833).
Explanation:
Jose and Jenna competed in a bike race. After 30 minutes, Jose had finished 2/3 of the race, and Jenna had finished 7/12 of the race. To determine who had finished more of the race, we can compare these two fractions by finding a common denominator or converting them to decimal form.
First, let's convert them to decimal form:
2/3 is approximately 0.6667
7/12 is approximately 0.5833
Comparing the decimal values, we can see that Jose's completion (0.6667) is greater than Jenna's (0.5833). Therefore, Jose had finished more of the race after 30 minutes.

Which table contains a set of non-linear ordered pairs?
Answer:
The table A contains a set of non-linear ordered pairs.
Step-by-step explanation:
To answer this question we have to recall what is the meaning of a linear ordered pair. As you can see, in every table there are 4 values for x, and 4 values for y. In every case, the set of values for x are
[tex]x=\{0, 1, 2, 3\}[/tex]
but in every table, the values for y varies. Now, the key is to calculate the variation of these values, and in order to have a linear relation between x and y, the variation must be the same quantity for every y value that depend of each x value.
For example, in table B, the variation is +3, as from the first y value to the second, 3 is added... and this +3 variation must be the same for each new value of y (and as you can see, 4+3 is 7, 7+3 is 10, 10+3 is 13).
Keeping this in mind, the variation in table C is -2, and the variation in table D is +1, so tables B, C and D contains sets of linear ordered pairs.
To answer the question, we just have to realise that table A has differents variations in the values of y, and this means that it contains a set of non-linear ordered pairs, wich is the correct answer to the question.
The sides of a square are two to the power of four-ninths inches long. What is the area of the square?
two to the power of the fraction sixteen over eighty-one square inches
four to the power of the fraction sixteen over eighty-one square inches
two to the power of eight-ninths square inches
four to the power of eight-ninths square inches
Answer:
2^(8/9) in²
Step-by-step explanation:
Make use of the identity ...
... (a^b)^c = a^(bc)
Here, you have a=2, b=4/9, c=2. There is an additional factor (units of inches) inside the parentheses on the left. For that, you use the identity
... (ab)^c = a^c·b^c
In this case a = 2^(4/9), b = in, c = 2.
So, the working of your problem is ...
... Area = (side length)^2 = (2^(4/9) in)^2 = (2^(4/9))^2 in^2
... = 2^(4/9·2) in^2 = 2^(8/9) in^2
The length of the rectangle is 7 inches, the width is w inches. If the coefficient of the width increases by 3, what could be an expression for the area of the rectangle?
Answer:
A = 10w
Step-by-step explanation:
In the area formula, the coefficient of width is length. Here, that is ...
... A = 7w
7 is the coefficient of the width. Increasing it by 3 makes it be 10, so we have ...
... A' = 10w
_____
Comment on the problem statement
The problem does not make it clear whether area stays the same as the coefficient increases. We have assumed that it does not.
Also, the coefficient of width in the area formula has units of inches. "Increases by 3" makes no sense in this context. It would make sense for it to increase by 3 inches. The result is very different if the increase is 3 microns, for example.

Answer:
A. 36°
Step-by-step explanation:
Same-length chords subtend same-measure arcs. Arc YZ has the same measure as its central angle (∠YOZ) and the same measure as arc XY (36°).
the measure of angle YOZ is 36°, which corresponds to option A. Therefore, the correct answer is option b.
The measure of an angle formed by two chords in a circle is half the measure of the arc intercepted by the angle.
If chord XY is congruent to chord YZ, it means that the arcs intercepted by these chords are also congruent.
So, if the measure of arc XY is "x" degrees, then the measure of arc YZ is also "x" degrees.
Now, the angle YOZ is formed by these two congruent arcs. Therefore, the measure of angle YOZ is half the measure of the arcs XY and YZ.
Angle YOZ = 0.5 * (x + x) = 0.5 * 2x = x degrees.
Now, if you're given the measure of arc XY (or YZ), you can substitute that value into the formula to find the measure of angle YOZ.
The answer choices you provided are in degrees, so the correct answer is A. 36°, assuming you have the measure of the arc XY (or YZ) in the problem.

At a high school with 800 students, 80% of the students ride the school bus. if 20 students are selected randomly (without replacement) and we let x = the number of students in the sample who ride the bus, what is the probability that at least one of the students doesn't ride the bus?
Answer:
0.9885 (98.85%)
Step-by-step explanation:
Since sample is less than 10% of the population, we can use binomial distribution to approximate the probability.
So we want to calculate P( X < 20 ).
We can calculate the probability of complement event P( X = 20 ).
Use binomial formula b(x; n, p) = C( n, x ) p^(x) (1-p)^(n-x)
b( 20; 20, 0.8 )
= C( 20, 20 ) (0.8)^(20) (0.2)^0
= (0.8)^20 ≈ 0.0115
So since P( X < 20 ) = 1 - P( X = 20 ), we have
P( X < 20 ) ≈ 1 - 0.0115 = 0.9885
The required value of probability for the given sample is given as 0.9885.
How to find probability using binomial distribution?The binomial distribution is based on the binomial theorem which can be written as (a + b)ⁿ = ⁿC₀aⁿb⁰ + ⁿC₁aⁿ⁻¹b¹ + ⁿC₂aⁿ⁻²b²+ ....+ ⁿCₙa₀bⁿ.
In order to use in the probability, there should be events independent of each other and the sum of there probabilities is 1.
Total number of students are given as 800.
The probability of students riding the school bus is 80% = 0.8.
Then, probability of students not riding the school bus is 1 - 0.8 = 0.2.
The probability of finding at least one student out of 20 not riding the bus is given as,
1 - P(All of the students ride bus)
It can be solved using binomial distribution as follows,
⇒ 1 - ²⁰C₂₀(0.8)²⁰(0.2)⁰
⇒ 1 - 0.0115 = 0.9885
Hence, the probability that at least one of the students doesn't ride the bus is given as 0.9885.

If P(3,2) and Q(7,10) are the endpoints of the diameter of a circle, what is the area of the circle in square units?
To find the area of a circle given its diameter's endpoints, determine the diameter length, radius, and then calculate the circle's area using the radius.
Explanation:The area of a circle can be found using the distance formula between two points representing the diameter's endpoints. Given points P(3,2) and Q(7,10), the diameter length is calculated as sqrt((7-3)^2 + (10-2)^2) = sqrt(4^2 + 8^2) = sqrt(16+64) = sqrt(80).
Knowing that the radius is half the diameter, the radius, r = sqrt(80)/2 = 4*sqrt(5).
Finally, the area of the circle is A = pi*r^2 = pi*(4*sqrt(5))^2 = 80*pi square units.
Lane borrowed $1200 for a new drum set. She will be paying 6.5% in simple interest over the next 2 years. What is the total amount of interest she will be paying on the loan? Show Work
Answer:
Steplo-by-step explanation:loan is 1200.
The interest rate is 6.50
Pp 46.90
Cumulative payment $53.4
Total payments$1,282.93
Final answer:
Lane will pay a total of $156 in simple interest on the loan of $1200 over 2 years, calculated using the simple interest formula: I = PRT.
Explanation:
Lane borrowed $1200 at a simple interest rate of 6.5% for a period of 2 years. To calculate the total amount of interest that will be paid on the loan, we can use the simple interest formula, which is:
I = PRT
where I is the interest, P is the principal amount borrowed, R is the interest rate per year (expressed as a decimal), and T is the time in years the money is borrowed for.
First, we convert R to a decimal by dividing it by 100:
R = 6.5% / 100 = 0.065
Next, we substitute the values into the formula:
I = $1200 × 0.065 × 2
I = $1200 × 0.13
I = $156
Therefore, the total amount of interest that Lane will be paying on the loan over the next 2 years is $156.

The measure of an angle is three more than twice its supplement. What is the measure of the angle?
Answer: the angle is 1°+n×120°
1°, 121°, 241°
Step-by-step explanation:
Angles are taken modulo 360°, so 363° = 3°.
Angle plus supplement gives 180°.
Let a be angle, s be supplement of a.
So s = 180-a. Given a = 3 + 2s
a = 3 + 2(180 - a)
a = 3 + 360 - 2a = 363 - 2a
3a = 363° or 3° or 723°
a = 121° or 1° or 241°
a = 1°
s = 179°
2s = 358°
2s+3 = 361° = 1° (modulo 360)
a = 121°
s = 180-121 = 59°
2s = 118°
2s + 3 = 121°, as required.
a = 241°
s = 360+180-241 = 540-241 = 299
2s = 598
2s + 3 = 601 = 241 (modulo 360)

(hint: denote these events by o1,..., o6. then p(o1) = p, p(o2) = 3p, p(o3) = p,..., p(o6)= 3p. now use a condition on the sum of these probabilities to determine p. answer as an exact fraction or round your answers to three decimal places.)
Answer:
p = 1/12 = p(o1) = p(o3) = p(o5)
3p = 1/4 = p(o2) = p(o4) = p(o6)
Step-by-step explanation:
p(o1) +p(o2) +... +p(o6) = 1 . . . . the condition on the sum of probabilities
... p +3p +p +3p +p +3p = 1 . . . . substitute values
... 12p = 1 . . . . simplify
... p = 1/12 . . . . divide by 12
Then ...
... 3p = 3/12 = 1/4
Final answer:
The probabilities of rolling each face of a loaded six-sided die, where even numbers are three times more likely than odd numbers, are 1/9 for odd numbers (1, 3, 5) and 1/3 for even numbers (2, 4, 6), satisfying the condition that the total probability sums to 1.
Explanation:
The student is dealing with a probability question involving a "loaded" die. To find the probabilities for each face of the die, we assign a variable p to represent the probability of rolling an odd-numbered face and 3p for an even-numbered face. The sum of all probabilities must equal 1 because one of the outcomes must occur when the die is rolled. We can set up the following equation: p + 3p + p + 3p + p + 3p = 1.
Combining like terms gives us 9p = 1, so p = 1/9. Thus, the probabilities of rolling each face are as follows:
P(Odd) = 1/9 for faces 1, 3, and 5P(Even) = 3/9 or 1/3 for faces 2, 4, and 6This system satisfies the condition that all probabilities sum to 1, making it the correct distribution for this loaded die.

In symbols, parentheses are preferred for grouping:
... 6√(5) -4√7
or
... 6(√5)-4√7
As with your "end root" the grouping symbols are only needed to resolve the ambiguity of what's under the radical.

Answer:
option 2
Step-by-step explanation:
in the given triangle,
tan45° = 8/x
=> 1 = 8/x
=>x = 8
for y,
cos45° = 8/y
=>1/√2 = 8/y
=>y = 8√2
Answer:
x=8, [tex]y=8 \sqrt2[/tex]
Step-by-step explanation:
Consider the given right triangle,
As, [tex]\tan \Theta = \frac{Perpendicular}{Base}[/tex]
Consider [tex]\tan 45^{\circ}=\frac{x}{8}[/tex]
[tex]1=\frac{x}{8}[/tex]
So, x=8
As, [tex]\sin \Theta = \frac{Perpendicular}{Hypotenuse}[/tex]
Consider [tex]\sin 45^{\circ}=\frac{8}{y}[/tex]
[tex]\frac{1}{\sqrt2}=\frac{8}{y}[/tex]
So, [tex]y=8 \sqrt2[/tex]
Therefore, x = 8 and [tex]y=8 \sqrt2[/tex]
