graph the image of this figure after a dilation with a scale factor of 2 centered at the origin use the polygon tool to graph the dilated figure ! Please help 100 pts and brainliest
Answers
Answer:
For this answer, I will label the points. Starting at the top left, then top right, then bottom left and bottom right let the points be A, B, C, D.
The new coordinates will be
A(-4,10)
B(4,10)
C(-4,4)
D(4,4)
Step-by-step explanation:
The question is asking for a dilation which is a transformation that makes an image proportionately smaller or larger by a scale factor. The scale factor is how much smaller or larger the shape will be, if the scale factor is between 0 and 1 then it will shrink, if it is greater than one then the image will stretch (be larger). In this case, the scale factor is 2, therefore the image will stretch. Since the center of dilation is the origin, to find the new coordinates simply multiply each x and y value by the scale factor. So A's original coordinates (-2,5) become (-4,10) and so forth. Therefore the equation for this dilation is (x, y) → (2x,2y).
Answer:
See below
Step-by-step explanation:
Points given on the graph:
(-2, 2), (-2, 5), (2, 5), (2, 2)Dilation by a scale factor of 2 will result in coordinates doubled for each point:
(x, y) → (2x, 2y)And the new points will be:
(-2, 2) → (-4, 4)(-2, 5) → (-4, 10)(2, 2) → (4, 4)(2, 5) → (4, 10)See attached for the graph

In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 21% of your total grade, each major test is worth 24%, and the final exam is worth 31%. Compute the weighted average for the following scores: 90 on the lab, 98 on the first major test, 71 on the second major test, and 79 on the final exam.
Answers
Answer:
the weighted score is 82.03
Step-by-step explanation:
The computation of the weighted score is as follows
= Respective scores × respective test or exam and score
= 0.21 × 90 + 0.24 × 71 + 0.24 × 71 + 0.31 × 79
= 18.9 + 21.6 + 17.04 + 24.49
= 82.03
Hence, the weighted score is 82.03
We simply applied the above formula so that the weighted score could be come

A circle has an area of 256 square inches. If the radius of
the circle is multiplied by 4, what will be the area of the new
circle formed?
OA) 890 in.
OB) 1520 in.
OC) 4096 in
OD 5360 in.
Answers
Answer:
Option C (4096π in²)
Step-by-step explanation:
Area of the circle = 256π in²
We know that [tex]Area=\pi r^{2}[/tex] , where r = radius of the circle
So,
[tex]256\pi = \pi r^{2}[/tex]
Cancelling π from both the sides,
[tex]=> r^{2} = 256[/tex]
[tex]=> r = \sqrt{256} = 16[/tex]
The radius of the circle = 16 in.
When the radius is multiplied with 4 , new radius = 16×4 = 64 in.
New Area = [tex]\pi (64)^{2} =4096\pi \: in^{2}[/tex]
Answer: C

[tex]Area = 216\ in^2[/tex]
Step-by-step explanation:
Given
[tex]L = 6[/tex] --- length
Required
Determine the surface area
The surface area of a cube is calculated as follows:
[tex]Area = 6L^2[/tex]
Substitute 6 for L
[tex]Area = 6 * 6^2[/tex]
[tex]Area = 6 * 36[/tex]
[tex]Area = 216[/tex]
Hence, the surface area of the cube is [tex]216in^2[/tex]

Heya, the correct answer is David. The tricky part is the Hours and minutes difference. by dividing 360 by 6 we'll get 60. That equals an hour. Which is what the original answerer got wrong.

Find the rectangular coordinates of (7, 150°)
Answers
Answer:
The coordinates are (-7sqrt(3)/2, 7/2).
Step-by-step explanation:
The rectangular coordinates from polar coordinates is found by:
x = r*cos(theta)
y = r*sin(theta)
Substituting the given values, we get:
x = 7*cos(150 deg) = 7*(-sqrt(3)/2) = -7sqrt(3)/2
y = 7*sin(150 deg) = 7*(1/2) = 7/2
The coordinates are (-7sqrt(3)/2, 7/2).

Answer:

Step-by-step explanation:
The growth factor is the ratio of the values at the end and beginning of the second year:
multiplier = 188.10/180 = 1.045 = 1 + 4.5%
The amount put out is the amount at the end of the first year, divided by this growth factor.
P = A/(1+r) = 180/1.045 = 172.25
The sum put out is ₹172.25, and the rate of interest is 4.5%.

24 = 31.4n + (-8.4) is the correct answer
Step-by-step explanation:
expression 31.4n -8.4 = 24 is the correct equation for the given sentence.
What is an expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Given, twenty-four is the same as 31.4 times a number plus negative 8.4.
Let " n " be the number
From the given data expression will be,
31.4 times a number
=> 31.4 * n
plus negative 8.4
=> 31.4n -8.4
Equals to twenty-four
=> 31.4n -8.4 = 24

Option 1: 28 is the correct answer.
Step-by-step explanation:
The given expression for sum is:
[tex]\[ \sum_{n=1}^{4} {2n+2} = 1 \][/tex]
There will be four terms in the sum
We have to find the terms by putting n=1,2,3,4 as n=1 to 4
Putting n=1
[tex]=2(1)+2 = 2+2 = 4[/tex]
Putting n=2
[tex]=2(2)+2 = 4+2 = 6[/tex]
Putting n=3
[tex]=2(3)+2 = 6+2 = 8[/tex]
Putting n=4
