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.
This can be translated in two ways.
or
Either way, the only way that this could be equal to 0 is if x = 0.
Therefore the solution is x = 0.
or
Either way, the only way that this could be equal to 0 is if x = 0.
Therefore the solution is x = 0.
