Answer:
y=65+ 30x
Step-by-step explanation:
Given data
Cost of rental= $65
Additional month= $30
The expression for the total cost for x months is
y=65+ 30x
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
Y = -4x + -3
sorry if i’m wrong
To set this up, use the function f(x) = a(b)^x
where a is the starting value ($9000 in this case)
where b is the rate of change (1.46% would be (1+0.0146) in this case)
and x is the amount of time.
insert value into the equation to get
f(x) = 9000(1+0.0146)^3
and your answer would be
$9399.98
You would have to multiply the weight by how many there are.
3 3/4 x 3 = 11 1/4
Therefore they would weigh 11 1/4 ounces.
