Can someone please help me with this math problem? Added questions:
a. How long will it take the T-shirt to reach its maximum height?

b. What is the maximum height?

c. What is the range of the function that models the height of the T-shirt over time?

If you make you answer for clear i can answer it : )

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
