Answer:
4,000 L/h
Step-by-step explanation:
First we'll find the amount of the change.
18,000 - 6,000 = 12,000 L
The time of the volume change was 3 hours: 0230 - 0530
Since we're looking for liters per hour, we will divide the liters (12,000) by the hours (3)
12,000/3 = 4,000 L/h
The point of inflection is calculated by equating the second derivative to zero and determining x from there.
f"(x) = -x²2xsinx² + cosx²(2x) = 0
2xcosx² - 2x³sinx² = 0
2x (cosx² - xsinx²) = 0
2x = 0 ⇒ x = 0
cosx² - xsinx² = 0 ⇒ x = 3.82 (if you use shift+solve in your scientific calculator)
Thus, the function only has 1 point of inflection and it is at x = 0.
It should look like a vertical line on the 2 of the x axis and everything to the right would be shaded.
Answer:
thanks so much for the free points!!
Step-by-step explanation:
Answer:
A:- This polynomial has a degree of 2, so the equation x^2+x-12=0 has exactly 2 roots.
B:-The quadratic equation x^2+x-12=0 has two real solutions, x= 3 or x= -4
Step-by-step explanation:
1) A quadratic equation always has 2 real roots.
2) Solving the equation,
factorisation method,
x^2+x-12=0
x^2-3x+4x-12=0
x (x-3) +4 (x-3)=0
(x-3)(x+4)=0
thus x=3 or x=-4
