Step-by-step explanation:
take 6-2 to get 4
4 is your common difference for ex.
-6+4 = -2
-2+4=2
2+4=6. You have to two pick an easier numbers out of the problem to find your common difference. Then check your answer to make sure it is right.
Because the number inside the parenthesis is less than 1, the population is decreasing every year. The initial population is the 12500. In terms of percentage, .98 is 98%, and the difference between 98% and 100% is 2%, so the population is decreasing by 2% every year. The population after 10 years requires you to replace the t in the equation with a 10. Doing that gives you a population of 10213.4
Angle 4 is the same as angle 6, 75 degrees, there are alternate interior angles.
