M=0 The slope is zero
Hope this helps
Answer:
It takes 3 seconds for the diver to reach the water.
Step-by-step explanation:
The height, in feet, is given by the following equation:

How many seconds will it take for the diver to reach the water?
He reaches the water when his height is 0, that is, when h(t) = 0. So







There are no negative instant of time, so just t = 3.
It takes 3 seconds for the diver to reach the water.
If the roots are 1 and 3, the factors of this quadratic are (x-1) and (x-3).
The polynomial is x^2 - 4x + 3.
If you were supposed to write a polynomial based upon all four given roots, then:
Looks as tho' you have four distinct roots. The 4th order polynomial with these roots is f(x) = (x-1)(x-3)(x-7)(x-2). Multiply this out, combine like terms and then arrange the terms in descending order by powers of x.
