Use a graphing utility to plot the data and graph the model in the same viewing window.

(a) Solve the Gompertz equation dy/dt=ryln(K/y),subject to the initial condition y(0)=y0. Hint: You may wish to let u=ln(y/K).(b) For the data given in Example 1 in the text (r=0.71 per year,K=80.5×106 kg, y0/K=0.25), use the Gompertz model to find the predicted value of y(2).(c) For the same data as in part (b), use the Gompertz model to find the timeτat which y(τ)=0.75K.

The normal monthly precipitation at the Seattle-Tacoma airport can be approximated by the model $R=2.876+2.202 \sin (0.576 t+0.847)$ where R is measured in inches and t is the time in months, with t = 0 corresponding to January 1. (a) Determine the extrema of the function over a one-year period. (b) Use integration to approximate the normal annual precipitation. Hint: Integrate over the interval [0, 12].)(c) Approximate the average monthly precipitation during the months of October, November, and December.

How does the bird's life help you understand the lives of the oppressed?

a. The volume, V, of a cylinder is given by the formula V = $\pi r^2L$ where r is the cylinder’s radius and L is its length. Using this formula, write a C++ function named cylvol() that accepts a cylinder’s radius and length and returns its volume. b. Include the function written in previous Exercise in a working program. Make sure your function is called from main() and returns a value to main() correctly. Have main() use a cout statement to display the returned value. Test the function by passing various data to it.
