Driven by technological advances and financial pressures, the number of surgeries performed in physicians' offices nationwide has been increasing over the years. The function f(t)=0.00447t3+0.09864t2+0.05192t+0.8(0t15) gives the number of surgeries (in millions) performed in physicians' offices in year t, with t=0 corresponding to the beginning of 1986.
a. Plot the graph of f in the viewing window [0,15] × [0,10].
b. Prove that f is increasing on the interval [0, 15].

1. [Graph]
2. We substitute t=1 (any number from (0,15)) into f'(t)'
f(1)=13411˙2197281˙5192100000=0.23578

At t=0 the current to a dc electric motor is reversed, resulting in an angular displacement of the motor shaft given by 𝜃(𝑡) = (250 𝑟𝑎𝑑/𝑠 )𝑡 − (20.0 𝑟𝑎𝑑/𝑠 2 )𝑡 2 − (1.50 𝑟𝑎𝑑/𝑠 3 ) 𝑡 3 . (a) At what time is the angular velocity of the motor shaft zero? (b) Calculate the angular acceleration at the instant that the motor shaft has zero angular velocity. (c) How many revolutions does the motor shaft turn through between the time when the current is reversed and the instant when the angular velocity is zero? (d) How fast was the motor shaft rotating at t=0 when the current was reversed? (e) Calculate the average angular velocity for the time period from t=0 to the time calculated in part (a). A

Painful bone metastases are common in advanced prostate cancer. Physicians often order treatment with strontium-89 (89Sr), a radionuclide with a strong affinity for bone tissue. A patient is given a sample containing 4 mCi of 89Sr.
If 20% of the 89Sr remains in the body after 90 days, write a function of the form Q(t)=Q0ekt to model the amount Q(t) of radioactivity in the body t days after the initial dose.
b. what is the biological half-life of 89Sr under this treatment? Round to the nearest tenth of a day.

A car travels at 108 kph from A to B for t seconds, applies the brakes for 4 seconds between B and C to give the car a constant deceleration and a speed of 72 kph at C, and finally travels at this speed from C to D, also for t seconds. If the total horizontal distance from A to D is 3100 m, determine the distance between A and B.

A city recreation department offers Saturday gymnastics classes for beginning and advanced students. Each beginner class enrolls 15 students, and each advanced class enrolls 10 students. Available teachers, space, and time lead to the following constraints. ∙∙ There can be at most 9 beginner classes and at most 6 advanced classes. ∙∙ The total number of classes can be at most 7. ∙∙ The number of beginner classes should be at most twice the number of advanced classes.
a. What are the variables in this situation?
b. Write algebraic inequalities giving the constraints on the variables.
c. The director wants as many children as possible to participate. Write the objective function for this situation.
d. Graph the constraints and outline the feasible region for the situation.
e. Find the combination of beginner and advanced classes that will give the most children a chance to participate.
f. Suppose the recreation department director sets new constraints for the schedule of gymnastics classes. ∙∙ The same limits exist for teachers, so there can be at most 9 beginner and 6 advanced classes. ∙∙ The program should serve at least 150 students with 15 in each beginner class and 10 in each advanced class. The new goal is to minimize the cost of the program. Each beginner class costs $500 to operate, and each advanced class costs $300. What combination of beginner and advanced classes should be offered to achieve the objective? .
