Note:
A polynomial of order n is of the form

where the a's are constants.
Consider the given expressions.
x/5 + 2 Not a polynomial
35x² It is a polynomial of order 2
7x⁷ - x⁵ It is a polynomial of order 7
4x + √(x-1) It is not a polynomial
Answer:
The polynomials are
35x²
7x⁷ - x⁵
Answer: 4.4 seconds
<u>Step-by-step explanation:</u>
h(t) = -16t² + 315
Since we want to find the total time the baseball is in the air, we need to find the time (t) when the ball lands on the ground --> h(t) = 0
0 = -16t² + 315
-315 = -16t²
