From 2006 to 2010, the population of a town declined to 22,000. the population is expected to continue to decline at a rate of 2.8% each year. 20 points what will the population be in 2040? round to the nearest whole number. enter your answer in the box.

9384

In the year 2010, the population is P = 22000 which is the starting population. The rate is r = -0.028 indicating a decrease of 2.8% annually

A = P*(1+r)^t

A = 22000*(1+(-0.028))^t

A = 22000*(1-0.028)^t

A = 22000*(0.972)^t

Now plug in t = 30 to compute the population in the year 2040 (which is 30 years after 2010)

A = 22000*(0.972)^30

A = 22000*0.42656768

A = 9384.48896

A = 9384 rounding to the nearest whole number

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
