we are given the following triangles:

We are asked to determine the value of "y". To do that we will use the tangent of 25:

\tan 25=\frac{y}{x}

We solve for "y" by multiplying both sides by "x":

x\tan 25=y

Now, we take the tangent of 15:

\tan 15=\frac{y}{30+x}

Now, we solve for "y" by multiplying both sides by the denominator:

(30+x)\tan 15=y

Now, we set both values of "y" equal, we get:

x\tan 25=(30+x)\tan 15

now, we solve for "x". First, we apply the distributive property on the right side:

x\tan 25=30\tan 15+x\tan 15

Now, we substract

The barber’s profit each week depends on his charge c per haircut. It is modeled by p = -200c2 + 2400c – 4700. What is the reaso
Marianna [84]

Answer:

0 ≤ c ≤ 12

Step-by-step explanation:

The function can be rearranged to ...

p = 200c(12 -c) -4700

suggesting that revenue will be zero for a charge of 0 or for a charge of 12, and that fixed expenses are 4700. Charges less than 0 are uninteresting, and charges high enough to cause the number of customers to be negative also don't make any sense in this context.

Though out of the range of likely consideration, charges low or high enough to cause profit to be negative (more than 9.54, for example) seemingly can be reasonably modeled by this function.

<h3>Answer:</h3>

8

<h2><u>STEPS:</u></h2>

=57 times 4/57 times 2

=57/1 times 4/57 times 2

=4/2 times 2 (cancel common factor:57)

=4/1 times 2 (convert element to fraction 2= 2/1)

=4/1 times 2/1

Multiply the numbers (4 times 2)

=8/1 times 1 (Multiply the numbers 1 times 1)

Apply the fraction rule: a/1 =9

=8
