What is the overtime rate for lifeguard who regularly earns $8.75 per hour?

TEA [102]

The overtime rate is an added percentage to the regular rate. By how much percentage, this would depend on the place you're working. If your work in USA, under US federal labor and tax law, the rate would be 150%. Thus, the overtime rate would then be:

Overtime rate = $8.75/hour * 1.50 = $13.125/hour

Foil (x+9)(3x-4) I have been stuck for ever

Bess [88]

Answer:

$3x^2+23x-36$

Step-by-step explanation:

The foil method is used when multiplying 2 binomials. One is (x+9) and another is (3x-4). The steps of FOIL are:

Multiply the first terms
Multiply the outer terms
Multiply the inner terms
Multiply the last terms
Combine like terms

Let's do the steps on our problem:

1. multiply x and 3x. So we have x * 3x = 3x^2

2. multiply x and -4. So we have x * -4 = -4x

3. Multiply 9 and 3x. So we have 27x

4. Multiply 9 and -4. So we have -36

Listing the terms, we have: 3x^2 -4x + 27x - 36

We combine like terms and have: 3x^2 + 23x - 36

That's our answer.

If using the method of completing the square to solve the quadratic equation x^2 - 9x - 8 = 0, which number would have to be add

V125BC [204]

Answer:

Number: 28.25

Solution to Quadratic: $x=\frac{9}{2}\pm\frac{\sqrt{113}}{2}}$

Step-by-step explanation:

$x^2-9x-8=0$

$x^2-9x-8+28.25=0+28.25$ <-- 28.25 is the number you need to add

$x^2-9x+20.25=28.25$

$(x-4.5)^2=28.25$

$x-4.5=\pm\sqrt{28.25}$

$x=4.5\pm\sqrt{28.25}$

$x=\frac{9}{2}\pm\sqrt{\frac{113}{4}}$

$x=\frac{9}{2}\pm\frac{\sqrt{113}}{2}}$
