Answer:
y=5x+100
Step-by-step explanation:
x represents every square foot
Answer:
Analyzed and Sketched.
Step-by-step explanation:
We are given 
To sketch the graph we need to find 2 components.
1) First derivative of y with respect to x to determine the interval where function increases and decreases.
2) Second derivative of y with respect to x to determine the interval where function is concave up and concave down.

is absolute maximum

is the point concavity changes from down to up.
Here, x = 0 is vertical asymptote and y = 0 is horizontal asymptote.
The graph is given in the attachment.
V= length x width x height.
9 x 3 x 6 =162
162 inches cubed!
I have no clue ...I'm nt so good in maths
