Answer: 4 / 5

Reasoning:

1)  The function sine is defined as:

sin(x) = opposite-leg / hypotenuse

2) From the figure:

x = A
opposite-leg = 20
hypotenuse = 25

3) Calculations:

sin(A) = 20 / 25 = 4 / 5

Answer: 4 / 5

The evaluation of the function requested as a fraction in lowest terms is :

<h2>Sin ∠A = 4/5</h2>

<h3>Further explanation</h3>

Firstly , let us learn about trigonometry in mathematics.

Suppose the ΔABC is a right triangle and ∠A is 90°.

<h3>sin ∠A = opposite / hypotenuse</h3><h3>cos ∠A = adjacent / hypotenuse</h3><h3>tan ∠A = opposite / adjacent </h3>

There are several trigonometric identities that need to be recalled, i.e.

cosec ~ A = \frac{1}{sin ~ A}

sec ~ A = \frac{1}{cos ~ A}

cot ~ A = \frac{1}{tan ~ A}

tan ~ A = \frac{sin ~ A}{cos ~ A}

Let us now tackle the problem!

Look at ΔABC in the attachment.

We will use the following formula to find the sine value as a fraction in lowest terms.

sin ∠A = opposite / hypotenuse

\sin \angle A = \frac{BC}{AB}

\sin \angle A = \frac{20}{25}

\large { \boxed{ \sin \angle A = \frac{4}{5} } }

The function p(x) = - 2(x-9)2 + 100 is used to determines the profit on T-shirts sold for x dollars. What would the profit from
dolphi86 [110]

ANSWER

$28

EXPLANATION

The profit function is given as:

p(x) =  - 2 {(x - 9)}^{2}  + 100

where x is the price of the T-shirt in dollars.

To find the profit on a T-shirt whose price is $15, we substitute x=15 into the function and simplify.

p(15) =  - 2 {(15 - 9)}^{2}  + 100

We simplify to get:

p(15) =  - 2 {(6)}^{2}  + 100

p(15) =  -72+ 100

p(15) =  28
