Answer:
C. 5
Step-by-step explanation:
Triangle BED is enlarged by scale factor 4.
(25-x)/4 = x
Multiply both sides by 4.
25-x = 4x
Add x on both sides.
25 = 5x
Divide both sides by 5.
5 = x
Answer:
50 miles
Step-by-step explanation:
x = (30 - 5) / 0.50
<em>Subtract To Solve Parentheses</em>
x = 25 / 0.50
<em>Divide</em>
x = 50
We are considering the function

the graph of this function is the graph of the parent function

after applying the following steps.
1. multiply by -1:

is

reflected with respect to the x-axis.
2. multiply by 5:

is

shrinked towards the y axis.
for example, consider x=1/2

now this means that

is "lower" than

, which means there is a shrinking of the graph.
3. add 5:

is

shifted 5 units up.
4.
so the graph of the function a) opens down, b) is shifted 5 units up, c) is not wider than the parent function

Answer:
<h2>At the 7th bounce, the ball reached 2.3 feet height.</h2>
Step-by-step explanation:
The given expression is

This exponential function represents the movement of a bouncing ball after being dropped.
represents the bounce number.
So, at 7th bounce means
, replacing this value in the function, we have

Therefore, at the 7th bounce, the ball reached 2.3 feet height.
