Rotation 180clockwise about the origin • a reflection over the x-axis • reflection over the y- axis Triangle ABC has vertex A located at (2, - 3) . Using the coordinates of this point, explain how the three transformations map vertex A onto vertex A^ prime .
Answers
Answer:
After the first rotation
A^ prime = (- 2, 3)
After the next two transformations, A^ = A = (2. -3)
Step-by-step explanation:
Here we have that
Rotation of 180 °clockwise about the origin will result in the inversion of the vertex point A such that the coordinates will be (- 2, 3)
Reflection over the x axis and a reflection over the y axis combined will revert the triangle back to its initial position
Therefore after the first rotation
A^ prime = (- 2, 3)
After the next two transformations, A^ = A = (2. -3).

Step-by-step explanation:
tan θ = y / x
tan θ = 0.96 / 0.28
tan θ = 3.43
Option (1) will be the correct option.
Terminal angle:Terminal angle is the angle formed between the initial side and the terminal side (As shown in the figure). Tangent of this angle is the ratio of opposite side and the adjacent side.
[tex]\text{tan}\theta=\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
Given in the question,
A point (0.28, 0.96) lies on the unit circle.Terminal angle will be formed between the standard position and the terminal ray passing through the given point.
Hence, [tex]\text{tan}\theta=\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(θ) = [tex]\frac{PO}{OA}[/tex]
tan(θ) = [tex]\frac{0.96}{0.28}[/tex]

Surface Area?
Answers
The surface area of a rectangle can be calculated by multiplying its length by its width. Since the given dimensions are 8yd and 6yd, the surface area, or more accurately the area, would be 48yd2.
The answer is 48yd2.
Surface area in mathematics refers to the total measure of the exposed outer surfaces of a three-dimensional object, like a cube, sphere, or cylinder. It is calculated by finding the sum of the areas of all the individual surfaces. For example, in a cube, you would add the areas of all six square faces. Surface area plays a crucial role in geometry and real-life applications like packaging design and construction. It helps quantify the amount of material needed and aids in solving problems related to shapes and volumes.
The surface area of a rectangular prism (which includes a box or cuboid shape) is found using the formula: 2lw + 2lh + 2wh, where l equals length, w equals width (or breadth), and h equals height. However, if we are dealing with a rectangle, since it's a two-dimensional figure, the surface area would be its area, which can be found with the formula length x width.
In your case, you only provided the length and width so I would assume that we are dealing with a rectangle. Therefore, to find the area, you just need to multiply the length by the width: 8yd x 6yd = 48yd2.
The answer is 48yd2.

A paining measures 2.4 feet from the left to right it's hung on the center of the rectangle or wall measuring to 20 feet from left to right what is the distance between the right edge in the painting of the page of the wall reason that the paining does not tilt
Answers
Answer:
the distance between the right edge of the painting and right edge of the wall = 8.8 ft
Step-by-step explanation:
From the question, the painting is hung in center of a rectangular wall and so the distance between them on either side will be the same.
Thus, we will divide the length of the painting and wall by 2 to get 2.4/2 = 1.2 ft and 20/2 = 10 ft .
So, the distance between the right edge of the painting and right edge of the wall will be;
D = 10 - 1.2 = 8.8 ft
A bowl contains 4 tangerines and 5 clementines. John randomly selects one piece of fruit, and then Pam randomly selects one of the remaining pieces of fruit. What is the probability that John selects a tangerine and Pam selects a clementine?
Answers
Answer:
5/18
Step-by-step explanation:
There are 9 pieces of fruit in the bowl, tangerines and 5 clementines.
Assuming that they do not put the fruit back
P (tangerine) = number of tangerines/ total = 4/9
Then John keeps his and there are 8 pieces of fruit in the bowl,
3 tangerines and 5 clementines.
P (Clementine) = number of clementines/ total = 5/8
P (tangerine, no replacement, Clementine) = P (tangerine) * P (Clementine)
= 4/9 * 5/8 =5/18
Answer:
5/18
Step-by-step explanation:
1. Find each of their probabilities separately
2. John= # of tangerines/ total # of fruit
3. John = 4/9
4. Pam = # of clementines/ total # of fruit left
5. Pam= 5/8
6. Multiply the two together to get the probability that both pick the fruit they want
7. 4/9 times 5/8
8. 5/18

What is the total value of option A? C. What is the interest earned on option B? D. What is the total value on option B? E. Which is the better option?
Answers
Answer:
A) P = 240
B) P + Po = 1040
C) P = 270.58
D) P+Po = 1070.58
E) Option B (compound interest) is better, as it generates more interest for the same inicial value, rate of interest and time
Step-by-step explanation:
The formula for simple interest is:
P = Po*r*t
Where P is the interest earned, Po is the inicial value, r is the rate of interest and t is the time.
The formula for compound interest is:
P+Po = Po*(1+r)^t
So we have that:
A) P = 800*0.06*5 = 240
B) P + Po = 800 + 240 = 1040
C) P+Po = 800*(1+0.06)^5 = 1070.58 -> P = 1070.58 - 800 = 270.58
D) P+Po = 1070.58
E) Option B (compound interest) is better, as it generates more interest for the same inicial value, rate of interest and time
David has two cylinder shaped bottles of punch, each with a height of 12 inches and a radius of 2 inches. He wants to fill a half-sphere punch bowl to the brim with the punch. What should the radius of the punch bowl be to the nearest tenth of an inch to fill it entirely with the two bottles of punch?
Answers
Answer: 5.2 inches
Step-by-step explanation:
Hi, first we have to find the volume of the cylinder shaped bottles:
V = π r^2 h
where:
V =volume
r= radius
h= height
Replacing with the values given:
V = π 2^2 (12)= 150.80 cubic inches
Since there are 2 bottles
Total punch: 2V = 301.59 cubic inches
The formula for the volume of a half-sphere is
V = (2 / 3) π r3.
Since the half-sphere is filled with the two bottles of punch (301.59 cubic inches)
301.59 =(2 / 3) π r3.
301.59/ (2/3) π =r3
144 =r3
∛144 =r
5.2 inches =r

A banner has a length of 10 feet and an area of 7 square feet. What is the width of the banner?
Answers
Answer:
the width is 0.7 feet
Step-by-step explanation:
Well we know that area = length * width. We know both the area and length, but not the width. Let's substitute the area and length in this equation, and substitute x for the width.
7 = 10 * x, or 7 = 10x
Now, solve for the width, or x, by dividing both sides by 10.
7(/10) = 10x(/10)
7/10 = x
Simplify 7/10 = 0.7
So the width of the banner is is 0.7 ft!

Here is the complete question
Two rectangular prisms have the same volume. The area of the base of the blue prism is 2 1/6 square units. The area of the base of the red prism is one third that of the blue prism.
which statement is true?
a)The height of the red prism is one-third the height of the blue prism
B)The height of the red prism is the same as the height of the blue prism
C)The height of the red prism is six times the height of the blue prism.
D)The height of the red prism is three times the height of the blue prism
Solution
Since both prisms have the same volume, V = A₁h₁ = A₂h₂ where A₁ and A₂ are the areas of the red and blue prisms respectively and h₁ and h₂ are the heights of the red and blue prisms respectively. For the question, A₁ = A₂/3. Substituting this into the equation, A₁h₁ = A₂h₂
A₂h₁/3 = A₂h₂
h₁ = 3h₂ . So the height of the red prism is thee times the height of the blue prism.

A. f(x) increases by 3.5%
B. f(x) decreases by 3.5%
C. f(x) increases by a factor of 2460
D. f(x) decreases by a factor of 2460
Answers
Answer:
A. f(x) increases by 3.5%
Step-by-step explanation:
Given:
City of Thomasville.
Population in 2006, [tex]P_o[/tex] = 2460
Exponential function, f(x) = 2460(1.035) ^x ...equivalent to [tex]P=P_o(1+r)^t[/tex]
Function change at x = 2, 3
According to the question:
Plugging the values of x= 2 and x=3 we have to find the population at different x.
So,
At x= 2 At x=3
⇒ [tex]P_2=P_o(1+r)^t[/tex] ⇒ [tex]P_3=P_o(1+r)^t[/tex]
⇒ [tex]P_2=2460(1.035)^x[/tex] ⇒ [tex]P_3=2460(1.035)^x[/tex]
⇒ [tex]P_2=2460(1.035)^2[/tex] ⇒ [tex]P_3=2460(1.035)^3[/tex]
⇒ [tex]P_2=2622.4[/tex] ⇒ [tex]P_3=2707.7[/tex]
Percent change :
⇒ [tex]\triangle \% =\frac{Final\ value -Initial\ value}{Initial\ value} \times 100[/tex]
⇒ [tex]\triangle \% = \frac{(P_3-P_2)}{P_2} \times 100[/tex]
⇒ [tex]\triangle \% = \frac{(2707.7-2622.4)}{2622.4} \times 100[/tex]
⇒ [tex]\triangle \% = 3.5[/tex]
So,
The function f(x) increases by 3.5% option A is the right choice.

Suppose the Marshall Islands have an area of about 70 square miles. Suppose a rectangle, with sides x and 2x + 4, has an area of 70 square miles. Find the value of x?
Answers
Answer:
The value of x is 5.
Step-by-step explanation:
We are given the following in the question:
Area of rectangle = 70 square miles
The sides of the rectangle are:
[tex]w = x, l = (2x+4)[/tex]
Area of rectangle =
[tex]A = l\times w[/tex]
Putting values, we get.
[tex]70 = (2x+4)x\\\Rightarrow 2x^2 + 4x - 70 = 0 \\\Rightarrow 2(x + 7)(x - 5) = 0\\\Rightarrow (x+7) = 0, (x-5) = 0\\\Rightarrow x = -7, x = 5[/tex]
Since, the value of x cannot be negative as it represents side of a rectangle.
Thus, the value of x is 5.
