First, for end behavior, the highest power of x is x^3 and it is positive. So towards infinity, the graph will be positive, and towards negative infinity the graph will be negative (because this is a cubic graph)
To find the zeros, you set the equation equal to 0 and solve for x
x^3+2x^2-8x=0
x(x^2+2x-8)=0
x(x+4)(x-2)=0
x=0 x=-4 x=2
So the zeros are at 0, -4, and 2. Therefore, you can plot the points (0,0), (-4,0) and (2,0)
And we can plug values into the original that are between each of the zeros to see which intervals are positive or negative.
Plugging in a -5 gets us -35
-1 gets us 9
1 gets us -5
3 gets us 21
So now you know end behavior, zeroes, and signs of intervals

Answer:
0.81 (rounded to the nearest hundredth) & 81%
Step-by-step explanation:
150/185 = 30/37 ≈ 0.81 (rounded to the nearest hundredth)
0.81 is 81%
Answer:
One angle is 46° and the other angle is 44°
Step-by-step explanation:
Complementary angle means the angles add up to 90 so:
90 - 44 = 46
Answer:105 thats with reducing to
Step-by-step explanation: 15(21/3)
then 15/1 x 21/3 then simplify
15 x 21 over 1 x 3 then simplify 315/3 then reduce then get 105 is your anwser
I think x equals 54
Hope this helps
