The equation g(t) = 2 + 23.7t - 4.912 models the height, in meters, of a pumpkin t seconds after it has
been launched from a catapult.

1. Is the pumpkin still in the air 8 seconds later?
Explain or show how you know.

2. At what value of t does the pumpkin hit the
ground? Show your reasoning.

Use photo math 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.

The correct answer is d, hope this
