Answer:
∠C=90°
∠A=67°
∠B=23°
Step-by-step explanation:
For angle C:
Thales' Theorem states that an angle inscribed across a circle's diameter is always a right angle.
Therefore, since AB is the diameter(hypotenuse) then angle C is the right angle. (90°)
For Angle A:
The measure of arc BC= 134 degrees. We can just use a formula for an inscribed triangle. ∠A = 1/2 (mBC)
∠A= (1/2)134
∠A= 77°
For angle B:
All triangle angles all add up to 180. We can just subtract angles A and C from 180°:
∠B = 180-(90+67)
∠B = 23°
Using 4 equal-width intervals, show that the trapezoidal rule is the average of the upper and lower sum estimates for the integral from 0 to 2 of x squared, dx .
Split up the interval [0, 2] into 4 subintervals, so that
[tex][0,2]=\left[0,\dfrac12\right]\cup\left[\dfrac12,1\right]\cup\left[1,\dfrac32\right]\cup\left[\dfrac32,2\right][/tex]
Each subinterval has width [tex]\dfrac{2-0}4=\dfrac12[/tex]. The area of the trapezoid constructed on each subinterval is [tex]\dfrac{f(x_i)+f(x_{i+1})}4[/tex], i.e. the average of the values of [tex]x^2[/tex] at both endpoints of the subinterval times 1/2 over each subinterval [tex][x_i,x_{i+1}][/tex].
So,
[tex]\displaystyle\int_0^2x^2\,\mathrm dx\approx\dfrac{0^2+\left(\frac12\right)^2}4+\dfrac{\left(\frac12\right)^2+1^2}4+\dfrac{1^2+\left(\frac32\right)^2}4+\dfrac{\left(\frac32\right)^2+2^2}4[/tex]
[tex]=\displaystyle\sum_{i=1}^4\frac{\left(\frac{i-1}2\right)^2+\left(\frac i2\right)^2}4=\frac{11}4[/tex]
Enter a recursive rule for the geometric sequence.
10, −80, 640, −5120, ...
Answer:
an = 10 (-8)^(n-1)
Step-by-step explanation:
In a geometric series, each term is multiplied by a common ratio to get the next term. Such that:
an = a₁ (r)^(n-1)
Here, the first term, a₁, is 10. The common ratio, r, is -8, because each term is multiplied by -8 to get the next term. So:
an = 10 (-8)^(n-1)
Your answer is correct, well done!
The recursive rule of the geometric sequence is [tex]a_{n+1}= -8a_n[/tex] where a1 = 10
How to determine the recursive rule?The geometric sequence is given as:
10, −80, 640, −5120, ...
Start by calculating the common ratio (r)
[tex]r = \frac{a_{n-1}}{a_n}[/tex]
Substitute 2 for n
[tex]r = \frac{a_{2}}{a_1}[/tex]
Substitute known values
[tex]r = \frac{-80}{10}[/tex]
Evaluate the quotient
[tex]r = -8[/tex]
Substitute -8 for r in [tex]r = \frac{a_{n+1}}{a_n}[/tex]
[tex]-8 = \frac{a_{n+1}}{a_n}[/tex]
Cross multiply
[tex]a_{n+1}= -8a_n[/tex]
Hence, the recursive rule of the geometric sequence is [tex]a_{n+1}= -8a_n[/tex] where a1 = 10

What is the simplified version of [tex](2\sqrt{5}+3)(\sqrt{5}-1)[/tex]
ANSWER
EXPLANATION
We want to simplify:
[tex](2\sqrt{5}+3)(\sqrt{5}-1)[/tex]
Recall the distributive property;
(a+b)(c+d)=a(c+d)+b(c+d)
We apply this property to get,
[tex]2\sqrt{5}(\sqrt{5}-1) + 3(\sqrt{5}-1)[/tex]
We expand to get,
[tex]2 \times 5-2 \sqrt{5} + 3\sqrt{5}-3[/tex]
This simplifies to,
[tex]10 + \sqrt{5}-3[/tex]

Find the greatest common factor of 7w and 4m 3
Answer:
Greatest common factor = 1
Step-by-step explanation:
given algebraic expressions are 7w and [tex]4m^3[/tex].
Now we need to find about what is the greatest common factor that is GCF of given algebraic expressions 7w and [tex]4m^3[/tex].
7 is a prime number so that can't be factored more.
There is no common factor of 7 and 4 except 1.
there is no common factor of w and [tex]m^3[/tex].
Hence required greatest common factor of given algebraic expressions 7w and [tex]4m^3[/tex] is 1.

We have to solve the given expression [tex][(2)^{\frac{1}{2}}(2)^{\frac{3}{4}}]^{2}[/tex]
As we know [[tex]x^{a}.x^{b}=x^{a+b}[/tex]]
Now by solving the given expression by this identity
[tex][2^{\frac{1}{2}+\frac{3}{4}}]^{2}[/tex]
= [tex][2^{\frac{5}{4}}]^{2}[/tex]
= [tex]2^{\frac{(5)(2)}{4}}[/tex]
= [tex]2^{\frac{10}{4} }[/tex]
= [tex]2^{\frac{5}{2}}[/tex]
Therefore, the given expression can be represented by [tex]2^{\frac{5}{2}}[/tex].
William is planning to create a rectangular mosaic which measures 120 cm by 144 cm. The mosaic will be covered completely with square pieces of colored glass. William has decided that he will purchase only one size of glass squares, and he does not plan to cut any of the pieces. If the art supply store only sells the glass squares in whole-number side lengths (measured in centimeters), find the smallest number of squares which William could use for his mosaic.
Answer:
30
Step-by-step explanation:
We need to find the greatest common factor of 120 and 144.
First, write the prime factorization of both:
120 = 2³×3×5
144 = 2⁴×3²
Both have 2³ and 3 in common, so the GCF is:
GCF = 2³×3
GCF = 24
So the side length is 24 cm. The number of squares along the width is:
120 / 24 = 5
And the number of squares along the length:
144 / 24 = 6
So the number of squares need to fill the entire area is 5×6 = 30. This is the least number of squares with whole-number side lengths that he can use.

Answer:
• arc PS = 40°
• arc UV = 24°
Step-by-step explanation:
There are relationships between the arcs intercepted by secant lines and the angle the secant lines make with each other. In these problems, you are expected to make use of these relationships, along with others you have learned about triangles.
The relationships are basically these:
• when the secants intersect inside the circle, the angle between them is half the sum of the intercepted arcs.
• when the secants intersect outside the circle, the angle between them is half the difference of the intercepted arcs.
__
First problem:
The angle between the secants QS and PR is shown to be 50°. Intercepted arc QR is shown to be 60°. You are asked to find the other intercepted arc, PS. Based on the above, we know ...
∠POS = (1/2)(arc PS + arc QR)
50° = (1/2)(arc PS + 60°)
Multiplying by 2, we get ...
100° = arc PS + 60°
Subtracting 60°, gives ...
40° = arc PS
__
Second problem:
We need to name a couple of points so we can describe more clearly what is going on. Call the point on arc PS where line QT intersects it point R. Call the point where line QT crosses line SU point X. (Point X is the vertex of the 99° angle.)
The relations described above tell us ...
angle W = (1/2)(arc PS - arc UV)
In this equation, we only know the value of arc PS = arc PR + arc RS = 20° + 94° = 114°.
But, we know two of the angles in triangle QWX. They are angle Q = 36° and angle X = 99°. Then angle W must be ...
angle W = 180° -36° -99° = 45°
Now, we can finish the above equation involving arc UV:
45° = (1/2)(arc PS - arc UV) . . . . . put the values we know in the secant relation
90° = 114° -arc UV
arc UV = 114° -90° = 24° . . . . . . . .solve for arc UV

The Quotient is 8 and you would simplify if that's an option
if its not then I will tell you what else it could be
Answer:
Step-by-step explanation:
"What is the sum of 4/5 and 1/10, and how do I show that in this illustration?"
The result of this addition is 8/10 + 1/10, or 9/10; this is "the quotient" desired.
In the graph, we could divide each rectangle vertically, so that each half of each rectangle represents 1/10. Adding 8 and 1 of these newly-drawn rectangles results in 9 such rectangles, which corresponds to 9/10 as the sum of the two fractions.

Evaluate this exponential expression. 3 • (5 + 4)2 – 42 =
Final answer:
The expression 3 · (5 + 4)2 – 42 evaluates to 227, after applying the order of operations to add, square, multiply, and subtract the given numbers.
Explanation:
To evaluate the given exponential expression 3 · (5 + 4)2 – 42, we follow the order of operations, commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
First, we add the numbers inside the parentheses: (5 + 4), which equals 9.
Next, we raise this sum to the power of 2: 92, which is equal to 81.
Then, we calculate 42, which is 16.
Now, we multiply 3 by the result of 92: 3 · 81, giving us 243.
Lastly, we subtract 42 from this result: 243 – 16, yielding the final answer of 227.
The final result of the expression 3 · (5 + 4)2 – 42 is 227.

The answer is C. f(X)=-1/5x-4/5
Hope this helps !!
Answer:
[tex]f^{-1}(x)=-\frac{1}{5} x-\frac{4}{5}[/tex]
Step-by-step explanation:
It is called an inverse or reciprocal function of [tex]f[/tex] to another function [tex]f^{-1}[/tex] that fulfills that:
If [tex]f(a)=b[/tex], then [tex]f^{-1} (b)=a[/tex]

We change the x for the y
[tex]x=-5y-4[/tex]
Now, let's clear y
[tex]y=\frac{x+4}{-5}[/tex]
Ordering
[tex]y = -\frac{1}{5} x-\frac{4}{5}[/tex]
So, the inverse of the function [tex]f(x)=-5x-4[/tex] is:
[tex]f^{-1}(x)=-\frac{1}{5} x-\frac{4}{5}[/tex]

IQ scores are measured with a test designed so that the mean is 120 and the standard deviation is 12. Consider the group of IQ scores that are unusual. What are the z scores that separate the unusual IQ scores from those that are usual? What are the IQ scores that separate the unusual IQ scores from those that are usual? (Consider a value to be unusual if its z score is less than minus2 or greater than 2.)What are the IQ scores that separate the unusual IQ scores from those that are usual?
Answer:
Step-by-step explanation:
Here a score is considered to be "unusual" if higher than 2 std. dev. from the mean OR lower than 2 std. dev. from the mean.
Thus, any score lower than (120 - 2[12]), or 96, or higher than (120 + 2[12] ), or 144, is considered to be "unusual."
What is the similarity ratio of a cube with volume 216 m³ to a cube with volume 2744 m³
A. 3:7
B. 7:3
C. 36:196
D. 196:36
Answer:
A. 3:7
Step-by-step explanation:
The volume of the smaller cube is 216 m³.
The volume of the larger cube is 2744 m³
Let the similarity ratio be [tex]l:L[/tex]
The volume of these two cubes are in the ratio:
[tex]l^3:L^3=216:2744[/tex]
This implies that:
[tex](\frac{l}{L})^3 =\frac{216}{2744}[/tex]
We take the cube root of both sides to obtain:
[tex]\frac{l}{L} =\sqrt[3]{\frac{216}{2744}}[/tex]
[tex]\frac{l}{L} =\frac{6}{14}[/tex]
This simplifies to:
[tex]\frac{l}{L} =\frac{3}{7}[/tex]
Therefore the ratio is 3:7

Step-by-step explanation:
The directions tell you what you need to know. It is a matter of adding up the values shown and finding the missing number to make the total be -20. Of course, it works best to start with a row, column, or diagonal that has 4 numbers already.Then, you're only finding the 5th number.
You can start with either diagonal, column 1 or 4, and row 4 or 5. Filling the missing numbers in those spots (red) will let you find the remaining missing numbers (green, then blue).
The square at row 2, column 2 can be filled on the first round using the down-right diagonal. I have shown it as filled on the second round after row 5 column 2 is filled.
Using a spreadsheet can make this easier, because you can write formulas for the sums in each row, column, and diagonal. Then you're just making those sums be -20.
___
For example, consider the up-right diagonal. The sum of the given values, -6, 0, -4, -2, is -12. Then the spot at row 1, column 5 must be filled with -8 to make the sum be -20.
Which of the following is the best estimate of the direction of the given vector?
Answer:
The direction of the given vector is 45° N of W
Step-by-step explanation:
* Lets revise the four directions with the four quadrants
- The four directions are:
# North which represented by the positive part of y-axis
# South which represented by the negative part of y-axis
# East which represented by the positive part of x-axis
# West which represented by the negative part of y-axis
∴ The first quadrant is between the East and the North
∴ The second quadrant is between the West and the North
∴ The third quadrant is between the West and the South
∴ The fourth quadrant is between the East and the South
* The direction of any vector is tan Ф, where Ф is the angle between
the vector and the x-axis, then:
- The direction of North of East is 45° ⇒ first quadrant
- The direction of North of West is 45° ⇒ second quadrant
- The direction of South of West is 45° ⇒ third quadrant
- The direction of South of East is 45° ⇒ fourth quadrant
* Now lets solve the problem
∵ The direction of the vector is between the North and the West
(its vertex in the second quadrant)
∴ Its direction is 45° North of West
* The direction of the given vector is 45° N of W
find the ordered triple to represent u in u=3v-2/3w +2z if v=(4,-3,5) w=(2,6,-1) and z=(3,0,4)
Answer:
u=(14/3 ,-13,23/3)
Step-by-step explanation:
Given
u=3v-2/3 w+2z
And
v=(4,-3,5)
w=(2,6,-1)
z=(3,0,4)
Putting the values of v,w and z
u=3(4,-3,5)-2/3 (2,6,-1)+2(3,0,4)
u=(12,-9,15)-(4/3,12/3,-2/3)+(6,0,8)
=(12,-9,15)-(4/3,4,-2/3)+(6,0,8)
We will perform the addition first..
=(12,-9,15)-(4/3+6 ,4+0,-2/3+8)
= (12,-9,15)-(22/3,4,22/3)
Subtraction will give us:
=(12-22/3 ,-9-4 ,15-22/3)
=(14/3 ,-13,23/3)
Final Answer:
The ordered triple for vector u is then [tex]\( u = (17\frac{2}{3}, -13, 23\frac{2}{3}) \)[/tex]
Explanation:
To find the ordered triple that represents the vector u in the equation [tex]\( u = 3v - \frac{2}{3}w + 2z \)[/tex], we need to perform the vector operations on v = (4, -3, 5), w = (2, 6, -1) , and z = (3, 0, 4).
Step 1: Multiply vector v by 3.
[tex]\[ 3v = 3 * (4, -3, 5) = (3*4, 3*(-3), 3*5) = (12, -9, 15) \][/tex]
Step 2: Multiply vector w by [tex]\( -\frac{2}{3} \)[/tex].
[tex]\[ -\frac{2}{3}w = -\frac{2}{3} * (2, 6, -1) = (-\frac{2}{3}*2, -\frac{2}{3}*6, -\frac{2}{3}*(-1)) = (-\frac{4}{3}, -\frac{12}{3}, \frac{2}{3}) \\\\\[ -\frac{2}{3}w = (-\frac{4}{3}, -4, \frac{2}{3}) \\\\\[ -\frac{2}{3}w = (-1\frac{1}{3}, -4, \frac{2}{3}) \][/tex]
Step 3: Multiply vector \( z \) by 2.
[tex]\[ 2z = 2 * (3, 0, 4) = (2*3, 2*0, 2*4) = (6, 0, 8) \][/tex]
Step 4: Add the resulting vectors from steps 1, 2, and 3.
We add the corresponding components from each vector:
[tex]\[ (12, -9, 15) + (-1\frac{1}{3}, -4, \frac{2}{3}) + (6, 0, 8) \][/tex]
To add these, perform the addition component-wise:
- For the first component:
[tex]\[ 12 + (-1\frac{1}{3}) + 6 = 12 - 1\frac{1}{3} + 6 = 11\frac{2}{3} + 6 = 17\frac{2}{3} \][/tex]
- For the second component:
[tex]\[ -9 + (-4) + 0 = -9 - 4 = -13 \][/tex]
- For the third component:
[tex]\[ 15 + \frac{2}{3} + 8 = 15 + \frac{2}{3} + 8 = 23\frac{2}{3} \][/tex]
The ordered triple for vector u is then [tex]\( u = (17\frac{2}{3}, -13, 23\frac{2}{3}) \)[/tex].
However, to express this as a proper ordered triple, we usually write the components as fractions or decimals. So, let's convert the fractions into decimals:
[tex]\[ 17\frac{2}{3} = 17 + \frac{2}{3} = 17 + 0.666\ldots \approx 17.67 \\\\\[ 23\frac{2}{3} = 23 + \frac{2}{3} = 23 + 0.666\ldots \approx 23.67 \][/tex]
So the ordered triple for vector u in decimal form is approximately u = (17.67, -13, 23.67).
Please note that the approximation is to two decimal places. If exact values are desired, it is best to leave the answer in fraction form as [tex]\( u = (17\frac{2}{3}, -13, 23\frac{2}{3}) \)[/tex].
