Answer is :
cos⁻¹[(-1-4√7)/(√17, √8) = 173.33° ≈ 173°
The first one and the last one
The answer is C because the formula is 2 x pai x radius
Answer:
Quartic
Step-by-step explanation:
Given

Required
Name the polynomial
The question required that the polynomial be named based on its degree.
This implies that, we name the polynomial based on the highest power of x
Highest power of x = 4
When the highest power of x in a polynomial is 4, such polynomial is a quartic polynomial.
Hence, by degree; the polynomial is quartic
Set up both fractions as equal to each other then cross multiply to solve for x!
