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.
Answer: The side length of the pet shop sign=5/4 inches
Step-by-step explanation:
Given: Candy draws a square design with a side length of x inches for the window at the pet shop.
She takes the design to the printer and asks for a sign that has an area of square inches.
Let y(x) =
differentiating both sides w.r.t x we get
y'(x)=32x-40
to find critical point x ,Put y'(x)=0 then
⇒32x-40=0
⇒x=5/4
Therefore the side length of the pet shop sign=5/4 inches.
