What’s the correct answer for this question?
Damm [24]

Answer:

tan C = 3/4

Step-by-step explanation:

sin C = opposite over hypotenuse

sin C = 3/5

BC = 5

AB = 3

We can use the Pythagorean theorem

a^2 + b^2 = c^2

3^2 + b^2 = 5^2

9 + b^2= 25

Subtract 9 from each side

9-9+b^2=25-9

b^2= 16

Take the square root of each side

sqrt(b^2)= sqrt(16)

b = 4

AC = 4

Tan C = opp side/ adj side

tan C = AB/ AC = 3/4

A clerk earns $12 an hour. How much does the clerk earn for p hours of work?
Montano1993 [528]

Answer:

You can't do this without knowing the number of hours, but you can write an equation. The equation would be 12p. P means the number of hours they worked and 12 stands for how much they earn each hour. Therefore you would multiple both of them together.

Y= mx +b ; x is the slope and y is the y-intercept.

So in this case, our equation will be y= 3x + 19 :)

Add: 2x² - 8x -9 and 3 x² + 8x-2​
Delvig [45]

Answer:

<h2>5x^2 - 11</h2>

Step-by-step explanation:

We got to add these together so

2x^2-8x-9+3x^2+8x-2

the 2x^2 and 3x^2 add to 5x^2

the 8x and -8x cancel each other out

the -9 and -2 add to -11

so..

5x^2 - 11

I hope this helped :)
