Answer:
plug in "n" in the formula to get an answer
Step-by-step explanation:
A.) The temperature rises 10 degrees over 3 hours.
(To explain my reasoning is because at 0 hours the temperature was 30 then at 3 hours the temperature moved up to 40 and at 6 the temperature moved to 50 which means every 3 hours its moving up 10 degrees)
Your pay is described by a piecewise function p(t) where t is hours worked.

The domain of this function is the number of hours you can work in a week—zero to 168. The range is the set of values p(t) can take on, which we have said is p(0) to p(168). This problem, however, is asking for the range for a typical 40-hour week. That will be p(0) to p(40):
the interval [0, 280].
Answer:
1 7/15
Step-by-step explanation:
4/5 = 12/15
2/3 = 10/15
12/15 + 10/15 = 22/15 or 1 7/15
