To start, I had similar questions and I know that it takes 3 cones to fill a cylinder.
And as for the volumes:
V of a cylinder= V=π r<span>2 h (pi x radius squared x height)
Volume of a cone= V=</span><span>π r2 h/3 (pi x radius squared x height divided by 3)</span>

Ray needs help creating the second part of the coaster. Create a unique parabola in the pattern f(x) = (x − a)(x − b). Describe

MatroZZZ [7]

Answer:

1) The parabola equation faces up

2) The y-intercept = a·b

3) The zeros are x = a and x = b

Step-by-step explanation:

1) The given information are;

f(x) = (x - a)·(x - b) which gives;

f(x) = x² - (b+a)·x + a·b

For an equation of the form a·x² - b·x + c, if a is positive, then the parabola faces up, therefore, the parabola equation, x² - (b+a)·x + ab where a is equivalent to +1 faces up

2) The y-intercept is given at x = 0, which gives;

f(0) = 0² - (b+a)·0 + a·b

The y-intercept = a·b

3) From f(x) = (x - a)·(x - b), when f(x) = 0, we have either;

(x - a) = 0 or (x - b) = 0

Therefore;

The zeros are x = a and x = b

What are the zeros of the quadratic function? f(x)=3x2−300 Enter your answers in the boxes.

nata0808 [166]

Hi there!

We can find the zeros of a function by solving f(x) = 0. We find the following:

$3 {x}^{2} - 300 = 0$
Add 300 to both sides.

$3 {x}^{2} = 300$
Divide by 3.

${x}^{2} = 100$
Take the root and minus root of both sides.

$x = \sqrt{100} = 10 \\ or \\ x = - \sqrt{100} = - 10$

Therefore, the zeros are
x = 10 and x = -10.

~ Hope this helps you!
