$\frac{dT}{dt} =k(t-66)\\T=\int\ {k(t-66)} \, dt=K(\frac{t^2}{2} -66)+c\\when t=0,T=181\\181=K(0-66)+c\\181=-66k+c\\when t=6,T=139\\139=k(\frac{6^2}{2} -66)+c\\139=-48k+c\\181-139=-66k+48k\\-42=-18k\\7=3k\\k=\frac{7}{3} \\139=-48*\frac{7}{3} +c\\c=139+112=251\\T=\frac{7}{3} (t-66)+251\\now complete the question$

What are some situations in which estimating a sum or difference is useful? Why is it useful in these situations?

Setler [38]

What exactly are these situations can you tell me and maybe I could help you out.

How are the numbers 342 and 324 alike? How are they different

barxatty [35]

The difference between 342 and 324 is different because the digits 2 and 4 are flipped.

342 and 324 are alike because they have the same amount of digits. hope that helped.
