Answer:

Step-by-step explanation:
Hi!
Lets call:
T = temprature of the object
T₀ = temperature of surroundings
t = time
The rate of change of T is its derivative with respecto to time. If T > T₀, the object looses heat, so T decreases. Then, being k > 0:

In this case T₀ = 70ºF and k = 0.05/min. Then the differential equation is:

just separate the ramge and domain
Answer:
He is incorrect. The true greatest common factor is 8.
Step-by-step explanation
Although 4 is a factor of both numbers, 32 and 8 can both be factorized (multiplied) by 8 to have the given numbers as an outcome.
Ex. 4 * 8 = 32 ; 8 * 1 = 8
The answer is 0.6144÷1.6 =0.384
hope i help solving your question.
