8 = 4 + 2c
move 4 to the other side
the sign always changes when moving to the other side
8-4= 4-4+2c
8-4= 2c
4= 2c
divide both sides by 2 to get c by itself
4/2= 2c/2
Cross out 2 and 2 divide by 2 and then becomes 1*1*c= c
c= 4/2
Answer: c= 2
Answer:
Step-by-step explanation:
<u>Average Value of a Function</u>
Given a function g(x), we can compute the average value of g in a given interval (a,b) with the equation:
We use the given data
We now compute the indefinite integral with a u-substitution
We'll use the substitution u=lnx, du=dx/x. Then
Integrating
Since u=lnx
The average value is
Since lne=1, and ln1=0
D, it makes the most sense
