He cycled 6 miles at 12 miles per hour, which means he cycled for one half an hour.


His total miles was 4 + 6 = 10 total miles.

His total time was 1 hour +  one half an hour = 1.5 hours.


His average speed is total distance divided by total time:

10 / 1.5 = 6 2/3 miles per hour.

Module 3 DBA: What key features can be identified from graphs of polynomials of higher-
Black_prince [1.1K]

Answer: Polynomials are algebraic expressions that contain more than two terms. AN example would be: f(x) = x^3 + x^2 + x +1. This equation contains three terms, with the 3rd degree as its highest term. It also means that the graph passed three x-intercepts. This depends in the highest degree.
