Using the shell method, the volume is
Each cylindrical shell has radius 
(the horizontal distance from the axis of revolution to the curve 
); has height 
(the vertical distance between a point on the 
-axis in 
and the curve ).
Compute the integral.
Step-by-step explanation:
the members of B are 4,8,12
the members of C are 0 2 3
Step-by-step explanation:
7(4x + 9) - 4
= (7 × 4x) + (7 × 9) - 4
= 28x + 63 - 4
= <u>28x + 59</u>
So, 7(4x + 9) - 4 is equivalent to 28x + 59 (D)

Step-by-step explanation:
The trick is always to look at the number after the first decimal for rounding to 1 decimal place, if its above 5, you round it up to the next decimal; eg. 13.45 = 13.5 because the 5 will round it up,and if value below 5, you round it down; eg. 12.34 = 12.3 because the 4 is below 5 and the nearest 10th decimal is 3.
