Answer:
77
Step-by-step explanation:
2000 × 15% = 300
300 × 5 = 1500
2000 - 1500 = 500 population after 5 years
I believe the answer is B.
(xA+xB)/2, (yA+yB)/2 = (4,3)
(xA+xB)/2 = 4
(-2+xB) = 8 --> xB = 8+2 --> xB = 10
(yA+yB)/2 = 3
(6+yB) = 6 --> yB = 6-6 --> yB = 0
B = (10,0)
Using one of the above equations, you can find the value of x.
tan x = 84/13 => x = tan-¹(84/13)
x = 81.20°
Hope that helps
