1. A minivan was purchased for \$32,000. If the value of the minivan depreciates by \$1,700 per year, find a linear function that models the value V
of the car after t
years. Use the function and find the value of the car after 5
years.
2. Simplify tan x(csc x – sin x)
3. A research lab grows a type of bacterium in culture in a circular region. The radius of the circle, measured in centimeters, is given by
, where t
is time measured in hours passed since a circle of a 1cm radius of the bacterium was put into the culture. Express the area, A(t)
, of the bacteria as a function of time, and find the approximate area of the bacterial culture in 4
hours.
4. A pendulum moving in simple harmonic motion is modelled by the function , where
is measured in inches and t is measured in seconds. Determine the first time when the distance moved is 4 inches.
5. Solve .
6. Estimate the slope of the tangent line to
at x =2 by finding the slope of the secant line through (2,f(2))
and (2.001,f(2.001))
