The population of a city in thousands is modeled by the function f(t) = 250 - (1.01)
where t is the number of years after 1950. Which of the following are predicted by
the model? Select all that apply.
A. The population in 1950 was 250.
B. The population in 1950 was 250,000.
C. The population grows by 1 percent each year.
D. The population in 1951 was 275,000.
E. The population grows exponentially.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
