Answer:
-5x^2-2x
Step-by-step explanation:
When distributing, you multiply the term outside the brackets to all the terms in brackets.
If the term outside the bracket is negative, then when distributing/opening the brackets, the signs of the terms changes.
So in this prob. -x would multiply to both +5x and +2
-x*5x+-x*2
∴-5x^2-2x
Answer:
the volume of the solid generated by revolving the region bounded by the graphs of the equations about the x-axis is;
or 10.036
Step-by-step explanation:
Given the data in the question;
y =
, y = 0, x = 1, x = 2.
Now, using the integration capabilities of a graphing utility
y =
, y = 0
Volume = 
Volume = 
Volume =
Volume =
Volume =
Volume =
Volume =
or 10.036
Therefore, the volume of the solid generated by revolving the region bounded by the graphs of the equations about the x-axis is;
or 10.036
