<span>V(o) = 1/3 πr²h - old volume
</span>V(n) = 1/3 π(2r)²(h/2)=1/3 π(2r)²(h/2)=1/3*4/2* πr²h=1/3*2* πr²h
V(n)/V(o)=1/3*2* πr²h/1/3 πr²h=2/1
V(n)/V(o)=2/1 - ratio
the volume will be doubled
Answer: $1.13 or $1.125
Step-by-step explanation:
divide 18 by 16
Answer:
Step-by-step explanation:
f(x) = 50 - 2x
x = 0 when the vitamins are bought and none have been taken 9 that is day 0).
So the intercept on the y axis 50 - 2(0) = 50 represents this situation ( day = 0 and number of vitamins = 50).
When all the vitamins have been taken f(x) = 0 so we have
50 - 2(25) = 0 This is the intercept on the x axis ( x = 25 days).
Answer:
The answer to your question is Area = 49n² - 70n + 25
Step-by-step explanation:
Data
Length of the side = 7n - 5
Formula
Area of a square = side x side
Process
1.- Substitute values
Area = (7n - 5)(7n - 5)
2.- Expand
Area = 49n² - 35n - 35n + 25
3.- Simplify
Area = 49n² - 70n + 25
4.- The polynomial is 49n² - 70n + 25
