T = 12 min, T o = 80° C, T s = 50 °C, T ( 12 ) = 60° C
60 = 50 + ( 80 - 50 ) · e^(-12k)
10 = 30 · e^(-12k)
e^(-12k) = 0.3333...
ln ( 0.333.. ) = - 12 k
- 12 k = - 1.1
k = ( - 1.1 ) : ( - 12 ) = 0.0916
Answer: D ) 0.0916

Answer:
Factor the expression completely would be A -2.25(4.5+x)
Step-by-step explanation:

then the answer of -6.75+2.25x
Hope this Helps and have a great day!
Hello!
we put the a and y values into the equation
2(-6) - 4
2 * -6 = -12
-12 - 4 = -16
The answer is -16
