A power function of the form ()=^ f(x)=ax^b is used to model the wind chill , in degrees Fahrenheit, with wind speed
x, in miles per hour, when the temperature is 30°

A) It is the wind chill when the temperature is 30°
30 °F and the wind speed is 0 miles per hour.

B)It is the wind chill when the temperature is 0°
0° F and the wind speed is 0 miles per hour.

C) It is the wind speed in miles per hour when the temperature is 30° and the wind is 0.

D) It is the wind speed in miles per hour when the temperature is 0° and the wind chill is 0°.

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
