Answer:
the total charge is

Step-by-step explanation:
Since x is measured from the center, that means that x=0 is the center so the edges of the rod correspond to x=-6 and x=6. that meas that the total charge can be calculated as

separating the integral from -6 to 0 and from 0 to 6, taking into account that |x|=-x for x<0 and |x|=x for x >=0, we get
using the substitution x=-u in the first integral we get
which is the same as the first integral. Thus, the total charge is given by

integrating we get
The solution is when x= 1
Hope this helps!
A=20 is the answer. You divide 5 by both sides to get it, because you need to get a alone.
The answer is 0.9
Because the scatter plot is a positive liner relationship the answer would have to be positive but the liner relationship is not perfect so the value would not be 1.
