Answer:
I think it's B
Step-by-step explanation:
For f(-2), x will equal -2.
Plug the x-value into the equation:

A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator.
Solve 2^(-2):

Solve the problem:

f(-2) will equal
1/2.
Answer:
5.26 hours or 315.6 minutes
Step-by-step explanation:
If he travels 0.19 miles in 1 hour
Then 1 mile is traveled (1x1)/0.19

It would be -4. subtracting a positive is the same as adding a negative
Answer:
6
Step-by-step explanation:
a cube has sides of the same length hence its volume is obtain as cubed side.
we have the volume and we need the side:
![\sqrt[3]{216} =\sqrt[3]{3^{3} 2^{3} } = 3*2 = 6](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B216%7D%20%3D%5Csqrt%5B3%5D%7B3%5E%7B3%7D%202%5E%7B3%7D%20%7D%20%3D%203%2A2%20%3D%206)
