An aquarium with a square base has no top. There is a metal frame. Glass costs 8 dollars/m^2 and the frame costs 7 dollars/m. Th
aleksley [76]
Let x = one of the side lengths of the base.
Then area of the base = x². So volume of the base = x²h.
That gives us x²h = 20. Solving for x, we get x = √(20/h²).

Glass is needed to cover the sides of the aquarium. There are 4 sides and 1 base. Area of a side = hx = h√(20/h²). Area of the base = x² = 20/h. Total area of glass = h√(20/h²) + 20/h. So the cost for glass = 8 * [h√(20/h²) + 20/h] = 8 h√(20/h²) + 160/h.

Metal frame is needed along the edges of the sides. There are 4 edges on the top, 4 edges in the bottom and 4 vertical edges. So the total length of metal frame = 4x + 4x + 4h = 8 √(20/h²) + 4h. Then the cost for metal frame = 7 * [8 √(20/h²) + 4h] = 56 √(20/h²) + 28h.

So the total cost = 8 h√(20/h²) + 160/h +  56 √(20/h²) + 28h

Find the value of y for given value of x.
Scrat [10]
1.)x+5;x=3
(3) + 5
8


2.)7x;x=-5
7(-5)
35


3.)y=1-2x;x=9
y = 1 - 2(9)
y = 1 - 18
y = -17


4.)y=3x+2;x=0.5
y = 3(0.5) + 2
y = 1.5 + 2
y = 3.5 


5.)y=2x^3;x=3
y = 2(3^3)
y = 2(3)(3)(3)
y = 2(27)
y = 54


<span>6.)y=x/2+9;x=-12
y = (-12)/2 + 9
y = -6 + 9
y = -3</span>
