In a certain city the temperature in degrees Fahrenheit t hours after 9 am was approximated by the function T(t) = 50 + 13 sin ( πt 12) Find the average temperature during the period from 9 am to 9 pm. (Do not use you calculator to evaluate the integral. Do not give an approximate answer)

The average temperature during the period of 9 am to 9 pm is  58.276 ° F

Step-by-step explanation:

From the given information, the time given as 9 pm implies that t = 12, since there is a period of 12 hours between 9 am to 9 pm.

Hence,

Let the average temperature be represented with

Then:

Therefore, the average temperature during the period of 9 am to 9 pm is  58.276 ° F

v=1788.75

step-by-step explanation:

i belive that is the answer

hello 0xxbadwolfxx0,

2.6 x 10^9 is 2,600,000,000.

1.3 x 10^2 is 130

multiplying 130 and 2,600,000,000 would simply give you 200,000,000,000.

therefore, the answer would be d. 2.0 × 10^11.

i hope i ! warm regards, mae.
