A population of 20,000 is decreasing in size at a rate of 4.6% each year. Let A(t) represent the amount in the population after t years. (same as previous problem)
Determine when the population will reach below 5000. Round to the nearest thousandth of
a year

step-by-step explanation:

3024 rhe base is what up in worry about

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.
