Absolute value means ignore negative signs, so #38 is asking is 282 greater or less than 279. it's greater. #39 is negative of |-10| the absolute value signs work as parentheses too, so it's -(10) so -10

Answer:
k ≈ -0.06729
Step-by-step explanation:
The initial temperature difference is 85 -36 = 49 degrees. After 5 minutes, the temperature difference is 71 -36 = 35 degrees. The constant k is the natural log of the ratio of these temperature differences, divided by the time unit.
k = ln(35/49)/5 ≈ -0.06729
__
The equation for the temperature T of the can in the refrigerator is ...
T = 49e^(-0.06729t) +36
_____
<em>Additional comment</em>
Be careful with the sign. If you're filling in k in e^(-kt), then the sign of k will be positive. Above, we have taken the form of the exponential term to be e^(kt), so k is negative.
P=0,024 K=0.02 IDK BROOOOOOOOOOOOOOOOOOOOOOOO
It would be a A. parallelogram, B. Quadrilateral
