Answer:
A, C, F, G, I
Step-by-step explanation:
A relation is "odd" if it is symmetrical about the <em>origin</em>. That is, f(-x) = -f(x). Here are the symmetries of the graphs shown:
A: origin
B: y-axis
C: origin, and x- and y-axes
D: x-axis
E: no symmetry
F: origin
G: origin, and x- and y-axes
H: x-axis
I: origin, and x- and y-axes

Using the identity cos^2(A)=1-sin^2(A)
transform
integral of sin^2(πx)cos<span>^5(πx)dx
=</span>integral of sin^2(πx)[1-sin^2(πx)]^2 cos(πx)dx
=integral of [sin^2(πx)-2sin^4(πx)+sin^6(πx)]cos(πx)dx
using the substitution u=sin(πx), du=πcos(πx)dx
=integral of [u^2-2u^4+u^6] (du/π)
=1/π[u^3/3-(2/5)u^5+u^7/7] + C
back substitute u=sin(πx)
=1/π[sin(πx)^3/3-(2/5)sin(πx)^5+sin(πx)^7/7]
or
=sin(πx)^3/3π-2sin(πx)^5/5π+sin(πx)^7/7π
Its pretty easy remeber than 1kg eqauls 1000 grams (Kilo) means Thousand
so the 4 books would be 79,800 grams
