Answer:
Step-by-step explanation:
integral(x/(1+x^2)^2)dx
=(1/2)integral(2x/(1+x^2)^2)dx
=(1/2)[-1/(1+x^2)] +c
Answer:
-3/2
Step-by-step explanation:
Given two points, we can find the slope by
m = (y2-y1)/(x2-x1)
= (-7 - -1)/ (5-1)
= (-7+1)/(5-1)
= -6/4
= -3/2
Answer:
yes it is
Step-by-step explanation:
that is a lap every 6 seconds .
C is on the line and D is not on the line.
-1/2(-40)+1=21
-1/2(20)+1≠-11
