V=LWH
L=8
W=7
H=5
V=8*7*5=280 in^3
you need 280 in^3 of water
Given:
The volume of water in a tank is modeled by the function

where, x is the number of minutes after the faucet filling the tank is turned on.
To find:
The y-intercept and what does it represent in this context?
Solution:
We have,

Substituting x=0, we get



Therefore, the y-intercept is 2 and it represents the volume of water in a tank before the faucet filling the tank is turned on.
