<h3>Answer:</h3>
- y = -(x -3)² +3 . . . . (agrees with your answer)
- see the attachment for a graph
Factoring the leading -1 from the first two terms, we have ...
... y = -(x² -6x) -6
Adding 9 inside parentheses to complete the square, then adding the opposite amount outside parentheses, we have ...
... y = -(x² -6x +9) -6 +9
... y = -(x -3)² +3
A) The differential equation comes from the fact that the rate of temperature change is proportional to the difference in temperatures.
B) Find general solution by separating variables and integrating
:
C) Initial condition is t=0, T = 87
D) Total time elapsed is 10 minutes, new temperature is 84
solve for alpha
E) Temperature function is:
solving for t
Plug in T = 98.6
