Let H (6, 7) be (x₁, y₁) and I (-7, -6) be (x₂, y₂)
Mid point =
Mid point = [
Mid point =
Santiago is not correct, the mid point is (-0.5, 0.5)
The formula is
Effective interest rate = (1 + i/n)^n - 1
To solve this, you have to know that the first derivative of a function is its slope. When an interval is increasing, it has a positive slope. Thus, we are trying to solve for when the first derivative of a function is positive/negative.
f(x)=2x^3+6x^2-18x+2
f'(x)=6x^2+12x-18
f'(x)=6(x^2+2x-3)
f'(x)=6(x+3)(x-1)
So the zeroes of f'(x) are at x=1, x=-3
Because there is no multiplicity, when the function passes a zero, he y value is changing signs.
Since f'(0)=-18, intervals -3<x<1 is decreasing(because -3<0<1)
Thus, every other portion of the graph is increasing.
Therefore, you get:
Increasing: (negative infinite, -3), (1, infinite)
Decreasing:(-3,1)
Inverse proportional function
Answer: 57
Explanation:
The 57 and x are exterior alternate angles.
What does this mean?
Well the definition of exterior alternate angles is that if you have two parallel lines and you draw a line crossing them, the angles on the outside of the two lines equal each other!
