Answer:
The tissues each bride's guest used is 1.5.
Step-by-step explanation:
We are given that a total of 76 groom's guests and 64 bride's guests attended a wedding. The bride's guests used 96 tissues. The groom's guests used 152 tissues.
We have to find that approximately how many tissues each bride's guest used.
As we know that whenever we have to find the value of 'each item', we have to use division.
Number of bride's guests who attended a wedding = 64
Number of tissues used by the bride's guests = 96
So, the tissues each bride's guest used =
= 
=
= <u>1.5</u>
Hence, each bride's guest used approximately 1.5 tissues.
Answer:

Step-by-step explanation:
We are given that curves y=
is rotated about x=4 .
Given that y=0 and x=2
We have to find the volume V generated by rotating the region bounded by the curves with the help of method of cylindrical shells.
First we find the intersection point
Substitute y=0 then we get
0=
x=0
Hence, x changes from 0 to 2.
Radius =4-x
Height of cylinder =y=
Surface area of cylinder =
Volume V generated by the rotating curves
=
V=
V=![2\pi[\frac{12x^5}{5}-\frac{x^6}{2}]^2_0](https://tex.z-dn.net/?f=2%5Cpi%5B%5Cfrac%7B12x%5E5%7D%7B5%7D-%5Cfrac%7Bx%5E6%7D%7B2%7D%5D%5E2_0)
V=![2\pi[\frac{384}{5}-32]](https://tex.z-dn.net/?f=2%5Cpi%5B%5Cfrac%7B384%7D%7B5%7D-32%5D)
V=

Hence, the volume V generated by rotating the region by the given curves about x =4=
.
