It'd be AEC, the vertex are just the lines that create the point E
Answer:
Step-by-step explanation:
Since the coefficient of x^2 is positive, this quadratic is a parabola in the shape of a U, hence has a minimum.
We want to end up with the form (x-h)^2 + c. Since (x-h)^2>=0, this form shows that the minimum is achieved when x=h.
Completing the square will put the quadratic in the desired form. Note that:
(x-h)^2=x^2-2hx+h^2
Comparing this with the given form, we must have -8=-2h, or h=4. But we are missing h^2=4^2=16. We can add the missing 16 and subtract it elsewhere without changing the quadratic.
x^2-8x+16 + (16-4) = (x-4)^2 + 12
Now we know that at x=4 the quadratic has a minimum and that the minimum is 12.
The volume is 64... I hope it helps you from there you can around the answer to the nearest hundred
Answer:
x=-3 or x=-7/3
Step-by-step explanation:
Given
The equation,
9x - 5y = 29.
To find the value of y when x is 1.
Explanation:
It is given that,
That implies,
When x=1,
Hence, the value of y is -4.
