Answer:
Verified
Step-by-step explanation:
minutes to hours:
525600/60
8760
hours to days:
8760/24
365
so there are 525600 minutes in 365 days. Confirmed
B,C and D maybe . They seem like they make more sense
C(x) = 4x³+7x²-14x-6
Step-by-step explanation:
Given that the amount of water used in normal days is given by the equation;
W(x) = 5x³ +9x²-14x +9 -----(i)
The amount of decrease in water used is modeled by the equation;
D(x)= x³+2x² +15--------(ii)
To get the function C(x) that models the water used by the car wash on shorter day you subtract equation (ii) from equation(i)
5x³ +9x²-14x +9
- x³+2x² +15
-------------------------
4x³+7x²-14x-6
