Answer:
She Flipped the symbol
Step-by-step explanation:
Please don't cry. I will explain it to you. Just please don't cry.
She multiplied correctly. But in her end result, she flipped the symbol.
You only flip symbols when multiplying or dividing by a negative number.
I hope this helps! Please don't cry :)
Answer:
The relation between m and n is , m = n
Step-by-step explanation:
Given as :
The average for n class = 0.82 = 82%
The average for m class = 0.78 = 78%
The average for ( m + n ) class = 80%
So , 
= 82%
And 
= 78%
And , 
= 80%
So , 0.82×n + 0.78×m = 0.80× (m+n)
Or, 0.82×n - 0.80×n = 0.80×m - 0.78×m
Or, 0.02×n = 0.02×m
Or, 
= 
∴ = 1
I.e m = n
Hence The relation between m and n is , m = n Answer
Answer:
2pi/15
Step-by-step explanation:
The intersection of y=x and y=x^2 is (0,0) and (1,1)
Washer method
Prefered this method for this one since slices are perpendicular to axis of rotation
Integrate(Big circle - Small Circle)dx
Integrate(pi*(x)^2-pi*(x^2)^2)dx on x=0..1
Integrate(pi*x^2-pi*x^4)dx on x=0..1 is 2pi/15
Shells method
So I have to solve for x since I will be integrating with respect to y
The height of the the shell will be sqrt(y)-y
The radius will be y since that is the distance between axis of rotation in a point within the shell
Integrate(2*pi*r*h ) dy
Integrate(2*pi*(sqrt(y)-y)*y) dy on y=0..1 is 2pi/15
