Answer:
Expected population in 2015: 19,152.58 or 19,000 people
Step-by-step explanation:
Given the decreasing rate of 2.5% per year, and a population of 28,000 in the year 2000:
We can solve for the rate of decrease by using the formula:

where:
A = population by year 2015
a = initial population (in year 2000) = 28,000
r = rate of change (decrease by 2.5% annually or 0.025)
t = time (in number of years) = 15
Plug in these given values into the formula:



A = 28,000(0.684)
A = 19,152.58 or about 19,000 people in 2015

Answer:
77
Step-by-step explanation:
The sum of the measures of the two given arcs is 180°, the measure of semicircle ADC. Using this fact, we can find x and the measure of DC.
AD +DC = 180
(19x -49) +(5x +37) = 180
24x = 192 . . . . . . . . . . . add 12, simplify
x = 8 . . . . . . . . . . divide by 24
Then the measure of DC is ...
DC = 5x +37 = 5(8) +37 = 40 +37
DC = 77
Answer:Rewrite the expression substituting 5 for the x and simplify. Substitute for x and Simplify. 5(5). Answer. 25. -10. Expression a. 5x = b. -2x = C. X + 25 = d. 5x - 15 = e.
