Archy [21]
A. Factor 28 + 7g  7(g <span>+ 4) 

add 
28 </span><span>+ 7g 

= 7 (g </span>+ 4)

B. (12r + 15) – 65 Remove parentheses
12r+15-65

= 12r - 50 

C. 24 – (8p – 12)

24 - (8p - 12) = -8p + 36 

24 - (8p - 12)  -(8p - 12) 8p + 12

= 24-8p+12

Simplify 24-8p+12 

Group like terms
-8p+12+24

Add the numbers  12+24=36

Answer is -8p+36

Newton’s law of cooling states that the temperature of an object changes at a rate proportionalto the difference between the tem
Verizon [17]

Answer:

\frac{dT}{dt} = -0.05\;min^{-1}  (T-70\ºF)

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:

\frac{dT}{dt} = -k(T-T_0) \\

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

\frac{dT}{dt} = -0.05\;min^{-1}  (T-70\ºF)
