Which description is correct for the polynomial 4x² + 3x +5?
antoniya [11.8K]

Answer:

A. Quadratic trinomial

Step-by-step explanation:

You can easily eliminate B and C because trinomial means there are three terms. B has monomial (one term) and C has binomial (two terms).

Now you have A and D. D is cubic which means the first term (4x²) would have to be cubed (4x³). Quadratic means it is squared.

a ball is dropped from a height of 20 feet above the ground. The velocity v(s) of the ball after it has travelled a distance of
Lana71 [14]
<h2>We know that</h2>

The initial height is 20 feet above the ground.

The function to model the velocity is

v(s)=60s

Where <em>s</em> represents the distance in feet.

Mathematically, this function has all real numbers as a domain. However, that will no make sense for this situation, because it would use negative numbers for the distance <em>s</em> which does not make sense.

Therefore, the domain, in this case, would be all real numbers greater than or equal to zero, but less than or equal to 20.

<em>The reason for this domain is that the ball will go from 20 feet above the ground to zero feet on the ground.</em>

Using interval notation would be

D\colon\lbrack0,20\rbrack
