The gates of an amusement park are closely monitored to determine whether the number of people in the amusement park ever poses a safety hazard. On a certain day, the rate at which people enter amusement park is modeled by the function e(x)=0.03x^3+2, where the rate is measured in hundreds of people per hour since the gates opened. The rate at which people leave the amusement park is modeled by the function l(x)=0.5x+1, where the rate is measured in hundreds of people per hour since the gates opened. What does (e−l)(4) mean in this situation?

Sagot :

The meaning of (e−l)(4) in this situation is that there are 92 people in the amusement park 4 hours after the gates open.

How to explain the value?

e(x) =  0.03x³ + 2

l (x) =  0.5x + 1

Therefore, ( e - l) =   [ .03x^3 + 2 ]  -  [ .5x + 1 ] will be:

=  0.03x³  - 0.5x + 1

Therefore, (e - l ) (4)  =  0.03(4)³  - 0.5(4) +  1  = 92  

Therefore, it means that  4 hours after the park opens, the rate that the number of people is changing is 92 people per hour
