I AM BEGGING YALL, PLEASE HELP ME OUT

sweet-ann [11.9K]

Answer:

(2a,2b)

(-4a,b)

Step-by-step explanation:

for the first one

the x value of coordinate L is going to be twice the value of the x coordinate of k (a)

That being said the x value of L = 2a

The y value of L is going to be half the value of the y value of coordinate A ( 4b )

4b/2=2b so the y value of coordinate L is 2b

now we put the values as an ordered pair

The answer would be (2a,2b)

How do you do this math

Ber [7]

Answer:

Step-by-step explanation:

tanR = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

= $\frac{PQ}{QR}$

= $\frac{10}{24}$

= $\frac{5}{12}$

sinR = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

= $\frac{PQ}{PR}$

= $\frac{10}{26}$

= $\frac{5}{13}$

cosR = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

= $\frac{QR}{PR}$

= $\frac{24}{26}$

= $\frac{12}{13}$

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

What is the product of (x+3) (3x -2)?

velikii [3]

Answer:

3x²+7x-6

Step-by-step explanation:

Original Equation;

(x+3)(3x-2)

Multiply the first term by the second term.

x(3x-2)+3(3x-2)

Multiply x by 3x and x by -2

3x²-2x+3(3x-2)

And then multiply 3 by 3x and 3 by -2

3x²-2x+9x-6

Group like terms

3x²-2x+9x-6

Simplify

3x²+7x-6

(x+3)(3x-2)

x(3x-2)+3(3x-2)

3x²-2x+9x-6

3x²+7x-6
