Using the slope concept, it is found that the shuttle traveled 3.2 miles while Marion was watching.
<h3>What is a slope?</h3>
The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.
Initially, the angle of elevation is of 16º, with an elevation of 1 mi, hence:
Then, at the end, the angle will be of 74º, with the elevation remaining constant, hence:
The distance is:
The shuttle traveled 3.2 miles while Marion was watching.

Answer:
112,547.095 million
Step-by-step explanation:
Data provided in the question
Population of a city in 2005 = 18,000
In the year 2010, the city population = 45,000
Now to find out the projected population for 2015 we use the exponential model
where
P(0) = Initial population
r = growth rate
t = time
e = natural log
So,
So
r ≈ 0.1833
Now
= 112,547.095 million
