Unformatted text preview: roblems 11 - 14, use the scenarios in questions 6 - 8 to draw a velocity-time graph which presents the motion described on the grids below. Draw the horizontal axis. Label the axes propriately with units and scale. # P (t ) 1. A raccoon population in a southern region varies due to fluctuating food supplies. Assume the number of raccoons, P(t), is given by P(t) = 250 + 150 sint where t is the time, in years. Store the function for P(t) as Y1 in your calculator. Use the window of [0, 10] for t, to sketch the graph. On the sketch, show a point where P(t) is increasing, decreasing, and a point where it is not changing much. 2 76. 047- 250 - 2. 6047 4 , in Fears \$ \$4 10 10 12. Estimate the average rate of change of the raccoon population for t = 1 . The change in R(t) from 1 year to tis P(t) - P(1). So, the average rate of change for P(t) changes at the average rate r(t) given by r(t) =Complete the table of values of r (t) for each estimate. A.) Complete the table below to determine which is the best approximation? P ( 1.1 ) - P ( ) 1. 1 - 1 B.) What does this rate mean regarding the raccoon population? This rate means the Population is fluctuating P ( 1 ) = 252 . 618 P ( , 91 ) = 252, 522 P ( 1,001 ) = 252, 620 t P(.99) - P(1) P(1.001) - P(1) P(1.1) - P(1) .99 - 1 1.001 - 1 1.1 - 1 r (t ) 2. 6 2 2. 61 13. The instantaneous rate of change of P(t) at t = 1 is the limit that r (t) approaches as t approaches 1 [the limit of the average rates at t = 1] .

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
