Answer:
2/3
Step-by-step explanation:
Gradient of line
= (y1-y2) /(x1-x2)
= (3-(-1))/(4-(-2))
= (3+1)/(4+2)
= 4/6
= 2/3
Answer:
x^2+x + 1/4
Step-by-step explanation:
x^2+x
Take the coefficient of x
1
divide by 2
1/2
Square it
(1/2)^2 = 1/4
Add this to make a perfect square trinomial
Simplify the integrands by polynomial division.
Now computing the integrals is trivial.
5.
where we use the power rule,
and a substitution to integrate the last term,
8.
using the same approach as above.
