2 answers:
Answer:
degree of the polynomial is 5.
Step-by-step explanation:
We have been given the polynomial
We can rearrange the polynomial and write in standard form as
For the degree of the polynomial we see the highest exponent of the polynomial.
Degree = highest exponent
The highest exponent of the polynomial is 5.
Therefore, the degree of the polynomial is 5.

The general form of the regression model is .
Using the sinusoidal regression calculator, we get that,
a = 33.690
b = 0.887
c = 1.337
d = 81.684
That is, the sine regression model is .
Thus, option A is the sine regression model for the given data.
