If the question is the best way to factor it I would say: (x-4)(x-3)(x+5)
It is 6 because 1000 would not be the appropiate answer
A) We can use the linear approximation to estimate the amount of time it takes. We're given that the linear approximation to t at the point x = 0 is t(x) ≈ L(x) = d(1–(x/60)). If it drives 84 miles at 62 mi/hr, we'll plug 84 in for d and 62 – 60 = 2 in for x to approximate the amount of time it takes.
L(2) = 84(1 – 2/60) = 81.2 minutes
So the answer for part a is 81.2 minutes.
b) Exact time = Distance/Speed = 84/62 = 1.35 hours, which is equivalent to 1.35 * 60 = 81.3 minutes.
Marissa's claim was accurate. the average of these minute counts is 6 minutes, which is what Marissa claimed.
The degree of a polynomial is simply the monomial with a coeficient that has the highest degree.
6x^6 = 6 degree
9x^3 = 3 degree
3x^2 = 2 degree
-4x^10 = 10 degree
-9x^5 = 5 degree
-5x^6 = 6 degree
Because -4x^10 has the highest degree, the degree of this polynomial is 10.
