A calculator or spreadsheet is good for doing this sort of computation.

_____

You add up the magnitudes of the differences between the given y-value and the corresponding value you get from the equation. For the first couple of points, these values are ...

... |3 - (0.1·1 +2.9)| = 0

... |2.5 -(0.1·6 +2.9)| = |2.5 -3.5| = 1

The computation proceeds like this for the remaining 6 points, and the numbers added. The result is 24.5.

Sarah: 18

Brother: 24

The difference in ratio units is 4-3 =1. The difference in years is 6, so 1 ratio unit stands for 6 years.

Multiplying by 6, we have ...

... Sarah : Brother = 3·6 : 4·6 = 18 : 24

Sarah is 18; her brother is 24.

96 necklaces

To find out how many necklaces Camilla can make, we need to see how many times the required number of beads "goes into" the available number of beads.

Silver: 8160/85 = 96

Black: 2880/30 = 96

Camilla has enough beads to make 96 necklaces.

_____

Comment on this answer

Obviously, if one of the quotients is smaller than the other, Camilla can only make as many necklaces as are supported by the constraining resource.

Even if she had 3000 black beads (way more than 2880), she could still only make 96 necklaces (for example) because she would run out of silver beads making that 96th necklace. (There would be 120 black beads left over in that scenario.)

Multiplying 3 by a smaller number gives a smaller product.

The midpoint between (-1+9i) and B=(5-3i) is (2+3i).

The midpoint between (-1+9i) and B=(5-3i) can be found by taking the average of the real and imaginary parts separately.

For the real part, we take the average of -1 and 5 which is 2. For the imaginary part, we take the average of 9i and -3i which is 3i.

Therefore, the midpoint between (-1+9i) and B=(5-3i) is (2+3i).

Answer:

8x2 or (8)(2)

Step-by-step explanation:

The value of 1 hour is 2 widgets, in 8 hours simplified would lead to 8x2 which is 16 widgets.

This leaves you with 16 widgets made in 8 hours.

Frank can make 16 widgets by working 8 hours a day.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that at Frank's work he can produce 2 widgets every hour.

Thus if he produce 2 widgets in one hour, using Unitary method

In 1 hour Frank can make 2 widgets.

Thus in 8 hour work, Frank can make (2 * 8) widgets.

In 8 hour work, Frank can make 16 widgets.

A graph is attached

The equation is in slope-intercept form:

Here, the value of m (the slope) is 1/2, and the value of b (the y-intercept) is -3.

This means that point (0, -3) is a point on the graph. This point is on the y-axis, 3 units below the x-axis.

Slope is sometimes referred to as "rise over run." The slope of 1/2 means the line will rise 1 unit for each 2 units to the right. That is, for some point (x, y) on the ine, another point will be found at (x+2, y+1).

Given a point at (0, -3), another point will be (0, -3) +(2, 1) = (2, -2), and another point will be (2, -2) +(2, 1) = (4, -1).

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]

Answer:

So, our rate of exponential growth is is 6.93 %

Step-by-step explanation:

The formula for exponential growth rate is

A = P[tex]e^{rt}[/tex] .... (1

Here

P = is the initial investment

A = amount after certain time

As we are given after 10 years (t = 10) the investment doubles

so plugging A=2P and t= 10 into equation (1)

2P = P[tex]e^{10r}[/tex]

cancelling P on both sides

2 = [tex]e^{10r}[/tex]

taking natural log on both sides

ln (2) = ln ([tex]e^{10r}[/tex]

ln(2) = 10r(lne)

as ln(e) = 1

ln (2) = 10r

r = [tex]\frac{ln(2)}{10}  [/tex]

solving the natural log

r = 0.0693

or

r =6.93 %

So, our rate is 6.93 %

We have the triangle 30° - 60° - 90°.

The sides are in proportion: 2 : √3 : 1

[tex]a=7[/tex]

[tex]a\sqrt3=7\sqrt3[/tex]

The area of a trinagle AFD:

[tex]A_{\Delta}=\dfrac{1}{2}(7)(7\sqrt3)=\boxed{\dfrac{49\sqrt3}{2}}[/tex]

The area of a triangle ADF is 42.46 square units.

The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

Given that, in ∆ADF, m∠F=90°, AD = 14 and m∠D=30°

We know that, sinθ= Perpendicular/Hypotenuse

Now, sin A=FD/AD

sin60°=FD/14

⇒ √3/2 = FD/14

⇒ FD=7√3

sin30°=FA/AD

⇒ 1/2 =FA/14

⇒ FA=7

We know that, area of a triangle is 1/2 ×Base×Height

Area of ∆ADF

= 1/2 ×FD×FA

= 1/2×7√3×7

= 42.46 square units

Therefore, the area of a triangle ADF is 42.46 square units.

D) 10.2 ft

The mnemonic SOH CAH TOA reminds you that

... Sin = Opposite/Hypotenuse

You want to find the length of the side Opposite the 50° angle, given the Hypotenuse is 12 ft. Then the relation is ...

... sin(50°) = height/(12 ft)

Multiplying by 12 ft gives

... height = (12 ft)·sin(50°) ≈ 9.2 ft

The height of the platform is 1 ft up from this value:

... 9.2 ft + 1 ft = 10.2 ft

A. Yes, because both points are equidistant from the center of the circle.

The point (0, 5) is 5 units from the point (0, 0).

The point (0, -5) is 5 units from the point (0, 0).

The given points are equidistant from the circle center at (0, 0), so both will lie on the circle—along with any other points that are 5 units from (0, 0).

Combine the left hand side, then write both sides as powers of 6:

[tex]\log_64x^2-\log_6x=\log_6\dfrac{4x^2}x=2\implies6^{\log_6\frac{4x^2}x}=6^2[/tex]

[tex]\implies\dfrac{4x^2}x=36[/tex]

[tex]\implies x^2=9x[/tex]

[tex]\implies x^2-9x=x(x-9)=0[/tex]

[tex]\implies x=0,x=9[/tex]

Step-by-step explanation:

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)

Answer:

10.8 units

Step-by-step explanation:

As the equation represents the area of a rectangle

i.e.

length * width = Area

Now area is 285.12 units square

while length is 26.4

and width is represented by w

now putting in the formula it will become

26.4 * w = 285.12

dividing both sides by 26.4

[tex]\frac{26.4w}{26.4}=\frac{285.12}{26.4}[/tex]

this will become

w = 10.8 units

Which is the required width of the Rectangle

so answer is 10.8 units

You may solve this problem in two ways:

If you solve the inequality explicitly (divide both sides by 4), you get

[tex] \dfrac{4n}{4} < \dfrac{16}{4} \iff n < 4 [/tex]

So, if [tex] n [/tex] has to be stricktly less than 4, you can only choose 1, 2 and 3 as answers.

Alternatively, you can plug in all of the values you're proposed and check if the inequality holds:

If [tex] n=1 [/tex], you have [tex] 4<16 [/tex], which is true.

If [tex] n=2 [/tex], you have [tex] 8<16 [/tex], which is true.

If [tex] n=3 [/tex], you have [tex] 12<16 [/tex], which is true.

If [tex] n=4 [/tex], you have [tex] 16<16 [/tex], which is false.

So, again, only 1, 2 and 3 are solutions.

Answer:

C) horizontal reflection over y-axis and horizontal stretch

Step-by-step explanation:

1a- A vertical reflection over the x-axis occurs when a function [tex]f(x)[/tex] is transformed into [tex]f(-x)[/tex]

1b- A horizontal reflection over the y-axis occurs when a function [tex]f(x)[/tex] is transformed into [tex]-f(x)[/tex]

2a- A function is being compressed if [tex]f(x)[/tex] is multiplied by a positive factor k: [tex]k f(x)[/tex] with [tex]k>1[/tex]

2b- A function is being stretched if [tex]f(x)[/tex] is multiplied by a positive factor k: [tex]k f(x)[/tex] with [tex]k<1[/tex]

In our problem, the original function [tex]f(x)[/tex] is:

- Multiplied by 1/2, so by a factor which is smaller than 1, so we are in case 2b

- Transformed from [tex]f(x)[/tex] into [tex]-f(x)[/tex] (due to the negative sign in front of it), so we are in case 1b

So, overall, we had a horizontal reflection over the y-axis and a stretch of the function.

Answer:

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.

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:

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).

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.

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.

Answer:

Step-by-step explanation:

This is a system of inequalities such that:

[tex]\left \{ {{2x+3y\geq 2} \atop {3x-4y\leq 3}} \right.[/tex]

Let's start by solving for y for both equations:

Equation 1:

[tex]2x+3y\geq  2\\\\3y\geq -2x+2\\\\y \geq \frac{-2x+2}{3}[/tex]

Equation 2:

[tex]3x-4y\leq 3\\\\-4y\leq -3x+3\\\\y\geq -\frac{(-3x+3)}{4}[/tex]

Now if we substitute the 2nd y into the first equation we obtain:

[tex]2x+3(\frac{3x-3}{4}) \geq  2\\\\2x+\frac{9x-9}{4}\geq 2\\\\\frac{8x+9x-9}{4}\geq 2\\\\17x-9\geq 8\\\\17x\geq 17\\\\x\geq 1[/tex]

Now we will solve for the second equation using the first result of y and we obtain:

[tex]3x-4(\frac{-2x+2}{3}\leq 3\\\\3x+\frac{8x-8}{3}\leq 3\\\\\frac{9x+8x-8}{3}\leq 3\\\\17x-8\leq 9\\\\17x\leq 17\\\\x\leq 1[/tex]

And so our solution for the system of equations is:

[tex]x \leq 1\\and \\y\geq \frac{-2x+2}{3}[/tex]

As well as:

[tex]x>1\\and\\y\geq \frac{3x-3}{4}[/tex]

... 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:

This system satisfies the condition that all probabilities sum to 1, making it the correct distribution for this loaded die.
