The answer to the first part is D
We want to know when we brought it back in to the room. at that time
the temperature difference is 80 - 42 = 38 so we have to solve
<span>
38=9<span>e<span>^−.3344t</span></span></span> for t
this time we get
<span><span>38 / 9</span>=<span>e^<span>−.3344t</span></span></span>
<span>t=<span><span>ln(<span>38 / 9</span>)</span><span> / −.3344</span></span></span>
<span>t=−4.3</span>
so 4.3 minutes before 2:10
Answer:
f(18)=334
Step-by-step explanation:
- f(x)=13x+100

- f(18)=334
He drove 193 mile you subtract 33 from 113 which is 80 then add 80 and 113 together and you get 193
