8q and 6p because terms are the sets in between + - / and *
Seems like its already rounded to the nearest thousandth any questions let me know
When you are multiplying 2 numbers with exponents, you need to add the exponent. When you multiply an exponent with an exponent, you multiply them.
So,
(3^2 x 7^4) ^9
First multiply the base and add exponents = ( 21^6) ^9
= 21 ^6x9
21^54
The same rule applies for variables, just pretend there is an imaginary 1.

Using the quadratic formula we get

Therefore the tennis ball is at least 15 feet above the ground from 0.5 seconds to 2.04 seconds
