Explanation:

The perimeter of the track is the two circumferences of the semicircles (when combined, they form one circle, so we can just find the circumference of the circle) added to the lengths of the rectangle (

160

meters).

To find the circumference of the circle, we need to know the diameter.

Circumference of a circle:

d

π

or

2

r

π

, where

d

represents diameter and

r

represents radius

The diameter of the circle happens to be the same as the width of the rectangle. We know that the area of a rectangle is found by multiplying its length by its width. We know that the area is

14400

and that its length is

160

.

Width: area divided by length

14400

160

=

90

The diameter of the circle and the width of the rectangle is

90

meters.

Circumference:

90

⋅

π

=

90

π

→

If you are using an approximation such as 3.14 for

π

, multiply that by 90

Add

160

⋅

2

to the circumference since the lengths of the rectangle are also part of the perimeter.

160

⋅

2

=

320

90

320

Answer:

area = 22,272

Step-by-step explanation:

area = length * width

to calculate the width, we need the first segment using the pythagorean theorem

87^{2} + x^{2} = 145^{2}

7569 + x^{2}  = 21025

x^{2} = 13456

x = 116

length = 116 + 140 = 256

so

area = 87 * 256 = 22,272

Find the exact value of tan (arcsin (two fifths)). For full credit, explain your reasoning.
Hitman42 [59]
\bf sin^{-1}(some\ value)=\theta \impliedby \textit{this simply means}&#10;\\\\\\&#10;sin(\theta )=some\ value\qquad \textit{now, also bear in mind that}&#10;\\\\\\&#10;sin(\theta)=\cfrac{opposite}{hypotenuse}\qquad &#10;\qquad &#10;% tangent&#10;tan(\theta)=\cfrac{opposite}{adjacent}\\\\&#10;-------------------------------\\\\

\bf sin^{-1}\left( \frac{2}{5} \right)=\theta \impliedby \textit{this simply means that}&#10;\\\\\\&#10;sin(\theta )=\cfrac{2}{5}\cfrac{\leftarrow opposite}{\leftarrow hypotenuse}\qquad \textit{now let's find the adjacent side}&#10;\\\\\\&#10;\textit{using the pythagorean theorem}\\\\&#10;c^2=a^2+b^2\implies \pm\sqrt{c^2-b^2}=a\qquad &#10;\begin{cases}&#10;c=hypotenuse\\&#10;a=adjacent\\&#10;b=opposite\\&#10;\end{cases}

\bf \pm \sqrt{5^2-2^2}=a\implies \pm\sqrt{21}=a&#10;\\\\\\&#10;\textit{we don't know if it's +/-, so we'll assume is the + one}\quad \sqrt{21}=a\\\\&#10;-------------------------------\\\\&#10;tan(\theta)=\cfrac{opposite}{adjacent}\qquad \qquad tan(\theta)=\cfrac{2}{\sqrt{21}}&#10;\\\\\\&#10;\textit{and now, let's rationalize the denominator}&#10;\\\\\\&#10;\cfrac{2}{\sqrt{21}}\cdot \cfrac{\sqrt{21}}{\sqrt{21}}\implies \cfrac{2\sqrt{21}}{(\sqrt{21})^2}\implies \cfrac{2\sqrt{21}}{21}&#10;
