Answer: A, B, C, D

All four answers are to be checked off

Explanation:

Anything of the form x^0 will be equal to 1, whenever x is nonzero.

So 5^0 = 1

All of the answer choices mentioned simplify to 1. Dividing any nonzero value over itself yields 1, so that explains A and B.

Choice C should be fairly obvious, and choice D there isn't any simplification needed.

Determine whether the following statements are true and give an explanation or counterexample.
Furkat [3]

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.

Luke’s that seven pieces of wood on top of one another if each piece was 4/8 of a foot tall how tall was his pile
Ludmilka [50]

Answer:

6 1/2 feet or 78 inches tall

Step-by-step explanation:

You have to multiply 4/8 by 7/1

First you multiply the nominators: 4 × 7 = 28

Then you multiply the denominators: 8 × 1 = 8

So the fraction would be 28/8 and it simplifies to 7/2

You can turn it into an improper fraction by seeing how many times 2 will go into seven evenly, which would be 6 times with 1 half left over

Therefore it would be 6 1/2 feet or 78 inches tall
