Please help, no links please! Brainiest to best answer! The rate at which cars enter a parking lot is modeled by E(t)=30+5(t-2)(t-5)e^-0.2t. The rate at which cars leave the parking lot is modeled by the differentiable function L. Selected values of L(t) are given in the table below. Both E(t) and L(t) are measured in cars per hour, and time t is measured in hours after 5 AM. (t=0) Both functions are defined for 0≤t≤12.
a) How many cars enter the parking lot from time t=0 to time t=12?
b) Use a trapezoidal sum with the four subintervals indicated by the data in the table to approximate ( ∫upper 12 lower 2 ) L(t)=dt. Using correct units, explain the meaning of ( ∫upper 12 lower 2 ) L(t)=dt in the context of this problem.
d) For 0≤t≤6, 5 dollars are collected from each car entering the parking lot. For 6≤t≤12, 8 dollars are collected from each car entering. How many dollars from time t=0 to t=12?

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.

t

step-by-step explanation:

ever thing time 1 is a multiply by 1 it get  

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5
