Answer:
the answer i think is $259200
Step-by-step explanation:
if the bank charges 7.2% every year, and in this case it's 4 years, then that would mean it would be 28.8%(7.2 x 4), which means the answer would be 9000 x 28.8 which is 259200.
Hope it helped

a. Arithmetic average return
b. Historical variance (to 5 decimal places)
c. Standard deviation.
Answer:
x1 y1 x2 y2
(2 5) (-1 -4)
slope m = (y2-y1)/(x2-x1)
( -4 -5 )/( -1 -2 )
( -1/ -1 )
m= -1/-1

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.
