Answer:
Therefore the maximum height that the reach is 49 feet after 1.75 seconds.
Step-by-step explanation:
Given that,
A ball is thrown vertically upward. After t seconds its height is given by the function

where h is height in feet.
Maximum value:
Given function f(x)= at²+bt+c.
- Find the value
- Putting
in the given function. - The maximum value of the given function is
.
Here a= -16 , b=56 and c=0
The ball attains its maximum height when
s.
Putting the value of t in the given function

=49 feet
Therefore the maximum height that the reach is 49 feet after 1.75 seconds.
So start by putting the negative sign into the second polynomial.
-(6x^2-2x-9)
-6x^2+2x+9
then combine like terms with the first polynomial
5x^3+4x^2-6x^2-2x+9
and you will get
5x^3-2x^2+2x+9
Hope this helps you.
