Answer:
1. initial point is (2, 4)
reflected point is (-2, 4)
the coordinates are similar because they involve the same numbers, however, with the reflection across the Y axis, the X point became negative.
2. initial point is (2, 4)
reflected point is (2, -4)
again, same numbers but the X value becomes negative
Hope this helps!
Answer:
Y=4x+4
Step-by-step explanation:
if it grows 4 inches each year that means it's the slope
and 4 feet tall model is the y intercept cuz its what you begin with
The answer is 20!

Answer:
Step-by-step explanation:
(equation: 17-2.5=2)
17-2.5=2
<u>-2.5 </u>
<u>17=2</u>
<u>17 divided by 2 </u>
<u>8.5 is the </u>

Answer: 28.26
Step-by-step explanation:
What your looking for is called the annulus (or the difference of two concentric circles). You can find the annulus by subtracting the area of the inner circle from the area of the outer circle. Volume of a circle= πr²
You are given the diameter in these problems, so you need radius.
For the first circle (8 in one) :
8/2=4 r=4
A=3.14(4)²
A=50.24
For the second one (10 in one) :
10/2=5 r=5
A=3.14(5)²
A=78.5
To find the measure of the annulus, you subtract those numbers, getting 28.26
