A cylinder of height and radius is expanding. The radius increases at a rate of $0.1$\frac{in}{s}$$ and its height increases at a rate of $0.2$\frac{in}{s}$$ . What is the rate of growth of its surface area?

The surface area of a cylinder is given by the formula:

$A=2\pi $r^2$+2\pi rh$

To find the rate of growth over time, take the derivative of each side with respect to time:

$\frac{dA}{dt}$=4\pi r $\frac{dr}{dt}$+2\pi h $\frac{dr}{dt}$ + 2\pi r $\frac{dh}{dt}$

Therefore, the rate of growth of surface area is:

$$\frac{dA}{dt}$=4\pi (1in)\left(0.1$\frac{in}{s}$\right)+2\pi(1in)(4in)\left(0.1$\frac{in}{s}$\right)+2\pi(1in)\left(0.2$\frac{in}{s}$\right)$

The rate of growth of the population of Reindeer in Norway is proportional to the population. The population increased from 9876 to 10381 between 2013 and 2015. What is the expected population in 2030?

We're told that the rate of growth of the population is proportional to the population itself, meaning that this problem deals with exponential growth/decay. The population can be modeled thusly:

$p(t)=p_$0e^{kt}$$

Where is an initial population value, and is the constant of proportionality.

Since the population increased from 9876 to 10381 between 2013 and 2015, we can solve for this constant of proportionality:

$2k=ln($\frac{10381}{9876}$)$

$k=\frac{ln(\frac{10381}{9876}$)}{2}=0.0252$

Using this, we can calculate the expected value from 2015 to 2030:
