If an object is dropped from a height of 400 feet, the function h(t) = -16t? + 400 gives the height of
the object after t seconds. When will the object hit
the ground? Round the answer to two decimal
places.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
