Answer:
The length of shadow decrease at 0.48 m/s.
Step-by-step explanation:
The distance of man from building = x
Thus initially, x = 12
It is given that dx/dt= -1.3 m/s
Let the shadow height = Y
Now solve for the
when x=4
from the diagram (triangle) it can be seen similar triangles with similar base/height ratios.

Answer:
121.76
Step-by-step explanation:
the original price is 83.97. you would have to find 45% of that. you would do this by putting x/83.97= 45/100
multiply 45 and 83.97 to get 3778.65. then divide that by 100 to get 37.7865. Add that to 83.97 to get 121.7565. round it to the nearest hundreth to get the total of 121.76 dollars

The correct answer is 6.5 x 10^2.
We have the amount for 1 second. To convert to 5 hours, we need to multiply it by 60 and 60 and 5.
0.036 x 60 x 60 x 5 = 648
Or about 6.5 x 10^2
