Answer:
T4 = -2°F
Step-by-step explanation:
Given the following data;
Current temperature = 10°F
Constant, K = 3°F
Time, t = 4 hours
In four (4) hours, we have;
T = kt
Substituting into the equation, we have;
T = 3 * 4
T = 12°F
T4 = current temp - new temp
T4 = 10°F - 12°F
T4 = -2°F
Therefore, the temperature it will be in 4 hours is - 2°F.
Just add 360 to -800 until you end up with an angle between 0 and 360:
-800+360=-440
-440+360=-80
-80+360=280
So the angle is 280 degrees.

Answer:
D
Step-by-step explanation:
The average rate of change of a function over an interval a ≤ x ≤ b is found by:
Here, a is 0 and b is 3, so: 
Just plug in 3 for the first term and 0 for the second term in the numerator:
- First term: 
- Second term: 
So, the final answer is:
![\frac{[\frac{1}{2} (3^{3\frac{1}{2} })+3]-[\frac{1}{2} (3^{\frac{1}{2} })+3]}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B%5Cfrac%7B1%7D%7B2%7D%20%283%5E%7B3%5Cfrac%7B1%7D%7B2%7D%20%7D%29%2B3%5D-%5B%5Cfrac%7B1%7D%7B2%7D%20%283%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D%29%2B3%5D%7D%7B3%7D)
Thus, the answer is D.
Hope this helps!
