Question

Cancerous tumor in a mouse is treated
with a chemotherapy drug. After treatment, the rate of change in the size of the tumor (in cm³/day) is given by the function
r(t)= 0.0025e^0.25t - 0.1485e^-0.15t, where t is measured in days.
a. Find the value of t0 for which r(t₀) = 0.
b. Plot the function r(t), for 0 ≤ t ≤15, and describe what happens
to the tumor over the 15-day period after treatment.
c. Evaluate the function given and interpret the physical meaning of this integral.
