Answer:
8 dollars
Step-by-step explanation:
According to the Fundamental Theorem of Algebra, the number of roots of a polynomial is equal to the degree of the polynomial. The degree of the polynomial is the highest exponent of a term in the polynomial.
Looking at the function, the term with the highest exponent is 8x7. The exponent is 7; therefore, the function has 7 roots.
An easy way is to work out their speed. Speed = distance/time.
First part: Speed = 330/5.5 = 60 mph
Finally, the second part: time = distance / speed
So time = 720/60 = 12 hours
