Question

1. After a foreign substance is introduced into the blood, the rate at which antibodies are made is modeled by

f(t)=15t/9t^2+11

where f(t)f(t) is in thousands of antibodies per minute, and tt is measured in minutes with 0≤t≤1000≤t≤100. Assuming that there are no antibodies present at time t=0t=0, find the total number of antibodies in the blood at the end of 100 minutes. Round your answer to two decimal places.

Number of Antibodies (in thousands) =

2. The velocity of a car (in miles per hour) is given by

v(t)=10t−5t^2

where tt is in hours. Write a definite integral for the distance the car travels during the first 2 hours. Use your graphing calculator to find this distance.

Distance =
