Ok so 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
16x^2-40x+25square inches.
Let y(x) =16x^2-40x+25
If differentiating both sides w.r.t x we get
y'(x)=32x-40
And
to find critical point x ,Put y'(x)=0 then
32x-40=0
x=5/4
Given:U.S Flag - rectangle in shapescale of 0.5 cm = 1 inlength of the scale 2.5 cmwidth of the scale 4.75 cmperimeter of the scale = 2(L+W) = 2(2.5+4.75) = 2(7.25) = 14.5cmperimeter of the actual flag is:14.5cm * 1in/0.5cm = 29 inches.

Given:
Saving amount = $900
Cost of Laptop = $600
Cost of food = $60 every 2 weeks
Let x be the number of times Sara can withdraw money for food. The inequality would be:
60x + 600 <u><</u> 900
60x + 600 <u><</u> 900
<u> - 600 -600</u>
60x <u><</u> 300
<u>÷ 60 ÷60</u>
x <u>< </u>5
Sara can withdraw money 5 times or less for food.
