<span>Answer:
I assume you're looking for a time-weighed average rather than just the [H(0) + H(60)]/2 average.
Havg = (1/60)â«[20+980e^(-0.1t)]dt (evaluated from 0 to 60)
Havg = (1/60)[20t - 98e^(-0.1t)] evaluated from 0 to 60
Havg = (1/60)[20(60) - 98e^(-6) - 20(0) + 98e^(0)] = 1297.76/60 = 21.629 °C</span>
Step-by-step explanation:
A proof that square root of 2 is irrational. ... An equation x² = a, and the principal square root ... The number under the radical sign is called the radicand. ... the given square numbers, each product of square numbers is equal to what square ... are relatively prime -- and it will be impossible to divide n· n into m· m and get 2.

E. X to the negative 3
Answer:
The average velocity the entire trip was 43.25 mi/h
Step-by-step explanation:
In this case we have to calculate an average based on the miles traveled. First we have to calculate the total of miles traveled, then calculate the portion of the total travel of each and with this calculate the average speed during the trip. First the total miles traveled:
Now the percentages:
At 57 mi/h were 
At 44 mi/h were 
At 37.8 mi/h were 
Now multiplying the speed by the portion and summing them we can have the average velocity:
The average velocity the entire trip was 43.25 mi/h
0.300 + .020 + 0.006 would be 0.326 in expanded form.
