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?

Match the following terms with their definitions. 1. bisector of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c. 2. opposite rays a ray, , is the set of points beginning at point a and going infinitely in the direction of point b. 3. collinear points a line or segment that intersects the segment at its midpoint. 4. betweenness of points a set of two or more points all on the same line. 5. ray the distance between the endpoints of a segment. 6. space point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively. 7. midpoint of a segment a set of two or more points all on the same plane. 8. coplanar points the point on a segment that divides the segment into two equal segments. 9. length of a segment the set of all possible points. 10. line segment the set of two different endpoints and all points between them.
