2.) dT/dt = -t^2 + 3t
dT = (-t^2 + 3t)dt
T = -t^3/3 + 3t^2/2 + C
at 4:00 AM
80 = -4^3/3 + 3*4^2/2 + C
C = 80 + 4^3/3 - 3*4^2/2
C = 77.33
T = -t^3/3 + 3t^2/2 + 77.33
at 8:00 AM
T = -8^3/3 + 3*8^2/2 + 77.33
T = 2.67 deg
Answer:
D
Step-by-step explanation:
have a good day
Answer:
Step-by-step explanation:
<u>The inequality as per description is:</u>
- 25 + 5i ≥ 95
- 5i ≥ 95 - 25
- 5i ≥ 70
- i ≥ 70/5
- i ≥ 14
- i = [14, + ∞)
This is shown on the number line 3 on the picture or option C
You can solve for X when you can single it out to one side of the equal sign, but if you have more than one variable of X, x^2 or x^3 it might be harder to get X
