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.
Answer:
cost of a drink = $9.25
cost of a popcorn = $6.25
Step-by-step explanation:
Bella spends a total of $53.75 on 4 drinks and 3 bags of popcorn
Piper spends a total of $61.25 on 2 drinks and 7 bags of popcorn
Let d represent drinks and p represent popcorn
4d + 3p = $53.75
2d + 7p = $61.25 multiply second equation by -2
-2 × (2d + 7p) = $61.25 ➡-4d - 14p = -$122.50
Now add two equation
-4d - 14p + 4d + 3p = -$122.50 + $53.75 add the like terms (remember -4d will eliminate 4d)
-11p = −$69.25 ➡ 11p = $69.25 divide both sides by 11
p = $6.25 is the price for a bag of popcorn we can use this information to find the price for a drink
4d + 3p = $53.75 replace p with $6.25
4d + 3×6.25 = $53.75
4d + 18.75 = $53.75
4d = $37
d = $9.25
