810 total feet because 135 times 6 is 810
So in the proper form, the equation would by y = 3x + 15. This means it has a slope of 3. Perpendicular lines have slopes that are negative reciprocals. The negative reciprocal of 3 (or 3/1) is -1/3.
we can sue formula

where
P(t) is population after t years
P0 is initial population
k is growth rate
t is time in years since 1985
Let's assume
h(t)=P(t) is million
h_0=P_0 in million
we can replace it
and we get

Answer:
the length of the arc EG = 15.7 feet
Step-by-step explanation:
∵m∠EOG = 60°
∵ measure circle 360°
∴ 
∴ The length of the intercepted arc EG is 1/6 the length of the circle
∵Length circle = 2 π r
∴ Length arc EG =
× 2 × 3.14 × 15 = 15.7 feet
