PLEASE HELP! find f(-2) for f(x) = 2x^x

B .

Step-by-step explanation:

2 x 0.1111 = .2222

B.

Step-by-step explanation:

We need to find for

To do this, we need to replace each instance of x in the equation with -2

Now, we can remove the negative exponent by rewriting the equation

And now we can simplify

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
