Answer:
C
Step-by-step explanation:
If it is accurate then it would have gotten the correct weight, but by going down to the thousandths it would be precise
Answer:
From Larry's rate, the equation can be given as D = T/101010
Step-by-step explanation:
Larry's book has 400400400 pages
His reading rate is 101010 pages per day
Let D = Number of days to read the book
To get the number of days it takes fro Larry to read this book, we say
Total pages = Reading rate (pages/day) x Number of days
Let Total pages = T
and Reading rate = R
Hence;
D = T / R
From Larry's rate, the equation can be given as D = T/101010.
From the question,
ddd = 400400400 (pages) / 101010 (pages/day) = 3963.9 days
Hence, it takes Larry approximately 3964 days to read the book.
Answer:
cubic units
Step-by-step explanation:
We are to find the volume of the solid of revolution formed by rotating about the x--axis the region bounded by the given curves.
f(x)=2x+1, y=0, x=0, x=4.
The picture is given as shaded region.
This is rotated about x axis
Limits for x are already given as 0 and 4
f(x) is a straight line
The solid formed would be a cone
Volume = ![\pi \int\limits^a_b {(2x+1)^2} \, dx \\= \pi \int\limits^4_0 {(4x^2+4x+1)} \, dx \\=\pi [\frac{4x^3}{3} +2x^2+x]^5_0\\\\=\pi[\frac{4*4^3}{3}+2*4^2+4-0]\\=\frac{364\pi}{3}](https://tex.z-dn.net/?f=%5Cpi%20%5Cint%5Climits%5Ea_b%20%7B%282x%2B1%29%5E2%7D%20%5C%2C%20dx%20%5C%5C%3D%20%5Cpi%20%5Cint%5Climits%5E4_0%20%7B%284x%5E2%2B4x%2B1%29%7D%20%5C%2C%20dx%20%5C%5C%3D%5Cpi%20%5B%5Cfrac%7B4x%5E3%7D%7B3%7D%20%2B2x%5E2%2Bx%5D%5E5_0%5C%5C%5C%5C%3D%5Cpi%5B%5Cfrac%7B4%2A4%5E3%7D%7B3%7D%2B2%2A4%5E2%2B4-0%5D%5C%5C%3D%5Cfrac%7B364%5Cpi%7D%7B3%7D)
Answer to the question is -4
