Find the length of the missing side of the triangle

Mathematics
1 answer:
DENIUS [597]3 years ago
7 0
It is a right triangle, so we can use pythagorean theorem which states

a^2 + b^2 = c^2

Leg^2 + Leg^2 = Hypotenuse^2

9^2 + x^2 = 15^2

81 + x^2 = 225

x^2 = 144

x=12

Let C represent the cost in dollars and R represent the revenue in dollars. What is the break-even point? Use a table to help if
krek1111 [17]

Answer:

(5,225)

Step-by-step explanation:

The break even point is when the cost equals the revenue.

C=R

15x+150=45x

150=30x

x=5

Plug this back into the original equations to get the y value.

15*5+150=225

or 45*5=225

Use the graph below to answer questions 6, 7, and 8.
Andrei [34K]

Question 6: the slope is 3

Question 7: 5

Question 8: y=3x+5

Step-by-step explanation:

Using rise over run, You can see that it is 3 in rise and 1 in rise. 3/1 is 3. The y-int is 5 because that is where it touches the y-axis. The formula is y=mx+b where m is slope and b is y-int. Sub the other answers in to find the answer. Hope this helps! Pls mark brainliest!

Select the correct answer.<br><br> Which expression is equivalent to sin^2x-sinx-2/sinx-2?
ladessa [460]

Answer:

A

Step-by-step explanation:

We are given:

\displaystyle \frac{\sin^2(x)-\sin(x)-2}{\sin(x)-2}

To make it simpler and more clear, we can let u = sin(x). So:

\displaystyle \frac{u^2-u-2}{u-2}

Now, it becomes obvious that we can factor, which produces:

\displaystyle =\frac{(u-2)(u+1)}{u-2}

Cancel:

=u+1

And substituting back:

=\sin(x)+1

Hence, our answer is A.
