is 
.
We need to find percent of change in population.
So, percent change 
%
Here old population is and new population is
Plugging these value in formula we get,
Percent change 
Rounding to nearest tenth 2.6%
Answer:
a) 96 = 3.57√h
b) h ≈ 723.11 m
Step-by-step explanation:
<h3>a)</h3>
The equation you want to solve is the model with the given values filled in.
D(h) = 3.57√h . . . . model
96 = 3.57√h . . . . . equation for seeing 96 km to the horizon
__
<h3>b)</h3>
We solve this equation by dividing by the coefficient of the root, then squaring both sides.
96/3.57 = √h
h ≈ 26.891² ≈ 723.11 . . . . meters above sea level
Dustin would need to have an elevation of 723.11 meters above sea level to see 96 km to the horizon.
Answer:
Height of the ball after 3 seconds = 27.4 feet.
Step-by-step explanation:
h(t) = -4.9t^2 + 22t + 5.5
h(3) means the height of the ball at time 3 seconds after the ball was thrown.
h(3) = -4.9(3)^2 + 22(3) + 5.5
= 27.4 feet
