Answer:
A) When using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. True.
The Shell method is a technique used to find the volume of a solid of revolution. Here, we take thin shells with axis coinciding with the axis about which the region whose volume is to be found, is revolved.
B) If a region is revolved about the y-axis, then the shell method must be used. False.
This method can be used with any axis of rotation.
C) If a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y. True.
The washer method uses thin disks with infinite width but the shell method uses thin concentric shells with infinite width about the axis of revolution. So, the statement is true.
Answer:
Step-by-step explanation:
Set the cost equation C(l) = l3 – l2 + l + 2.5 equal to $11.00 and solve for l:
C(l) = 2l + 2.5 = $11, or
2l = 8.5, or l = length = 4.25 inches
The change in value was 8% which amounts to $1630
Further explanation:
The change in value is calculated by using the initial price and selling price of the car.
Given
Purchase Price = P = $21330
Selling Price = S = $19700
As the selling price is less than the purchase price, Cindy had loss.
Percentage of loss will be calculated as:
The change in value was 8% which amounts to $1630
