Answer:

FV= 5,958.67 = 5,959

Step-by-step explanation:

Giving the following information:

Current population (Present Value)= 3,810

Growth rate (g)= 3.5% annual

Number of periods (n)= 13 years

<u>To calculate the future number of people (FV), we need to use the following formula:</u>

FV= PV*(1+i)^n

FV= 3,810*(1.035^13)

FV= 5,958.67 = 5,959

The top row of seats behind home plate at Cincinnati’s Great American Ball Park is 90 ft above the level of the playing field. T

Serggg [28]

Using the slope concept, it is found that the base of the left field wall is 361 feet from a point on level ground directly below the top row.

<h3>What is a slope?</h3>

The slope is given by the <u>vertical change divided by the horizontal change.</u>

It's also the tangent of the angle of depression.

In this problem:

The vertical change is of 90 ft.

The horizontal change is of x.

The angle of depression is of 14º.

Hence:

$\tan{14^{\circ}} = \frac{90}{x}$

$0.249328 = \frac{90}{x}$

$0.249328x = 90$

$x = \frac{90}{0.249328}$

$x = 361$

Hence, the base of the left field wall is 361 feet from a point on level ground directly below the top row.
