Answer:
B = 
Step-by-step explanation:
Given
C = AB + D ( subtract D from both sides )
C - D = AB ( divide both sides by A )
= B
Answer:
a) -3.5
Step-by-step explanation:
The average rate of change of a function f(x) from x=a to x=b is given by:
We want to find the average rate of change of change of the given function from x=1 to x=4.
From the graph,


The average rate of change is:

a) is closest
The answer will be 62.4. We know this because of the next procedure:
<span>We know that:
the volume of a cylinder is pi * r^2 * h
the volume of a cone is 1/3 * pi * r^2 * h
the total height is 47.
the height of the cone is 12.
</span><span>the height of the cylinder must be 35.
Now, if the top half is filled with sand, then the volume of the sand is
pi * 4^2 * 36 and the volume of the cone is 1/3 * pi * 4^2 * 12.
the total volume = 1960.353816 cubic millimeters.
since the top drains at the rate of 10 * pi cubic millimeters per second, the top will be empty and the bottom full after 1960.353816 / (10 * pi) = 62.4 seconds.
I hope this answer is ok for you </span>
It can be or it depends on how the equation is set up
