In 1995, the population of a town was 33,500. It is decreasing at a rate of 2.5% per decade. a. Identify whether the function is a growth or decay function.

b. Write the function, f(n), that expresses the population of the town after (n) decades.

c. What is the population in the year 2025 to the nearest hundred?

Step-by-step explanation:

a. It is a decay function as number of population is decreasing over time

b. f(n) = 33500*((100 - 2.5)/100)^n = 33500*(0.975)^n

c. In year 2025, n = (2025 - 1995)/10 = 3

f(3) = 33500*(0.975)^3 = 31100 rounded up

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
