Answer:
The distance from the pole is 11.8 ft
Step-by-step explanation:
Let
x------> the distance from the pole
we know that
The tangent of angle of 28 degrees is equal to divide the opposite side to angle of 28 degrees ( the height of the pole) by the adjacent side to angle of 28 degrees ( the horizontal distance from the pole)
so
tan(28°)=6.3/x
Solve for x
x=6.3/tan(28°)=11.8 ft
The answer is A: a>= -3 and a <=3

Ok, find change then divide by years elapsed
change=310-280 million=30 million
number of years elapsed=10
30mil/10=3mil
3million per year was the population growth rate
