A volleyball player serves the ball from a height of 6.5 feet above the ground with an initial vertical velocity of 21 feet per
Vaselesa [24]

Answer:

Option D. H(t) = 6.5+21t-16t^2

Step-by-step explanation:

we know that

If air resistance is ignored, the height h (in feet) of the ball t seconds after it is served is given by

H(t) = - \frac{1}{2}g t^2 + V_0t + H_0

where

g is the acceleration due to gravity which on earth is approximately equal to 32 feet / sec^2

V_0 is the initial velocity (when t = 0 )

H_0 is the initial height (when t = 0)

In this problem we have

V_0=21\ ft/sec\\H_0=6.5\ ft

substitute the given values

H(t) = - \frac{1}{2}(32) t^2 + (21)t + 6.5

H(t) = -16t^2 + 21t + 6.5

Rewrite

H(t) = 6.5+21t-16t^2

2x^{2} is a monomial (since it is all connected by multiplication) and since it is in the degree of 2, that makes it a quadratic. 

-2 is a constant (since it doesn't have variables) and it is a monomial (since it is all connected by multiplication)

3x-9 is a binomial (since it has two terms, not connected by multiplication) and since it has x in the power of 1, that makes it a linear equation.

Finally, -3x^{2} -6x + 9 is a trinomial (since it has 3 terms connected by either addition or subtraction) and since the degree of the polynomial is 2, that makes it a quadratic.
