Answer:
20.24in^2
Step-by-step explanation:
r^2
3.14 times 16in
that is 50.24
6 times 5 = 30
50.24 - 30= 20.24
2p^2 + 3p - 4 - (-2p^2 - 3p + 4) =
2p^2 + 3p - 4 + 2p^2 + 3p - 4 =
4p^2 + 6p - 8 <==
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)
I’m not absolutely sure but I believe the answer is around 6
Step-by-step explanation: its A. the denominator has to be the same as the hypotenuse
