Option D
Money earned by Marty is $ 16.72
<em><u>Solution:</u></em>
Given that, Marty started a lawn mowing business
He kept track of his expenses and earnings in a table
Lawn Mower = - $49.99
Gasoline = - $8.79
Moyer's yard = $ 40
Griffen's yard = $ 35.50
To find: Money earned by Marty
Total money earned = lawn mower + gasoline + moyers yard + griffens yard
Total money earned = -49.99 - 8.79 + 40 + 35.50
Total money earned = -58.78 + 40 + 35.50
Total money earned = -18.78 + 35.50 = 16.72
Thus money earned by Marty is $ 16.72
The following expressions (1+cosβ)(1−cosβ)sinβ is equivalent to sin³β
<h3>What are Trigonometric Ratios ?</h3>
In a Right angled triangle , trigonometric ratios can be used to determine the value of angles and sides of the triangle.
The trigonometric expression given in the question is
(1+cosβ)(1−cosβ)sinβ
(a+b)(a-b) = a² - b²
( 1 - cos²β)sinβ
By the trigonometric Identity
1-cos²β = sin² β
sin² β x sin β
sin³β
Therefore Option B is the correct answer.
