You will need three roots for this, so we have
Let x = -30, -10 and +20
So the factors will be (x+30)(x+10)(x-20)
The divide it to 100, this will help bring the peak up and down
So the polynomial function R(x) will become
1/100 * (x+30)(x+10)(x-20)
R(x) = 1/100 * (x+30)(x+10)(x-20)
Finding the X-intercept:
Let R(x) = 0 and solve for x.
1/100 * (x+30)(x+10)(x-20) = 0
x = -30, -10, 20 are the x-intercepts.
Answer: Depends which one you need more.
Step-by-step explanation:
It will be 84° bcs all angles equal to 180. and if you subtract 32 and 64 from 180, you’ll get 84.
I pretty sure the answer is 6.25 hr.
I added 60 and 65. I divided that number with 20.
