FORMULA: AREA = LENGTH X WIDTH
with this we can proceed so the area is 20
the length is 40 inches and
answer is : width ----18.94---
Answer:
Step-by-step explanation:
Use Newton's Law of Cooling here:

where T(t) is the temp of something after a certain amount of time, t, has gone by; Ts is the surrounding temp, and T0 is the initial temp. k is the constant of cooling. We need to first solve for this using the information given. Filling in what we know:
which can simplify a bit to
and 
Take the natural log of both sides:

Taking the natural log allows us to pull that exponent down out front:

and now we can divide both sides by ln(38) to get
-35k = .794585 so
k = -.023
Now that have the value for k, we can go on to solve the rest of the problem which is asking us the temp of the soda after 70 minutes. Filling in using the k value and the new time of 70 minutes:
and
and
and
T(t) = 35 F, basically the temp of the fridge, which is not surprising!
Four to the fifth power is...
4•4•4•4•4=1,024
Answer: x = 4
Step-by-step explanation: f(2) = 3(2)-1 = 5. Meaning x needs to be a value that makes g(x) = 5. You can set them up equal to each other 5 = 2x-3 and solve. You end up getting x = 4.
Your speed is 13 ft/sec. In order to know our velocity, we would need to know what direction we're moving. You haven't told us anything about our direction, only that our speed is 13 ft/sec.
