What is the vertex of the function f (x) = x^2 + 16x?

Tju [1.3M]

f(x) = x^2 + 16x

Completing the square.

f(x) = a(x-h)^2 + k

f(x) = (x + 8)^2 - 64

h = -8, k = -64

Vertex = (h,k)

Vertex = (-8, -64)

Not fully explained, just a quick summary.

Last autumn, julia noticed something interesting as she blew up spherical balloons for harris's birthday party. she calculated t

Vikki [24]

To find whether the volume would be doubled when the radius is,we can find the volume of the two balloons.

The formula of a sphere is:
$\frac{4}{3} \pi \: {r}^{3}$
Let's take 丌 as 3.14

The volume of the balloon with 4cm radius:
$\frac{4}{3}(3.14) \times {4}^{3} \\ = 4.18667 \times 64 \\ = 267.94688$

The volume of the balloon with 8cm radius:
$\frac{4}{3}(3.14) \times {8}^{3} \\ = 4.18667 \times 512 \\ = 2143.57504$
As we can see,
267.94668 × 2 = 535.89 ≠2145.56

Thus,she wouldn't discover that the volume is twice as big when the radius is doubled.

Hope it helps!

If the Volume of a rectangular prism is 720 what is the width

Bess [88]

Answer:

The width of the rectangular prism is 9 cm.

Step-by-step explanation:

From the formula of the volume of a bar $V=whl$ we see that $w=\frac{V}{hl}=\frac{720}{8\cdot 10} = 9$ cm.
