Newton's law of cooling is
k (t₁ - t₂) = -ln (T₁ - T∞ / T₂ - T<span>∞)
Use the two data points in the given to find k.
t = 0, T = 154
t = 10, T = 133
Solution:
k(0 - 10) = - ln (154 - 71/ 133 - 71)
-10k = -0.291716
k = 0.02917 or 0.0292
So now find t when T = 100
0.2917 * ( 0 - t) = -ln (154 - 71 / 100 -71)
- 0.02917t = - 1.0515
t = 36. 05 minutes
to the nearest minute t = 36</span>
Answer:
The median is 5, mode is 5, and range is 12
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Because there's no change in x so it has to be a straight line going through the y-axis.
Also for A and C, they don't even touch y = 2 so you can easily cross those out.
