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

Mathematics

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.

Answer:

I think u have to find the distance.

Each point is given a distinct letter and like wise you have to count the distance between the two points given.

Step-by-step explanation:

Like, 1)distance between A and R when A = -11 and R = -9

their distance is 2 units.

Likewise, 2) RY = 6 units

3) EU = 7 units

4) WD = 5 units

One batch of muffins require 1/4 cup of sugar. Kelly wants to make 3/2 batch of muffins. Will she use more than, less than, or a
Alla [95]
She will use more than 1/4 cup of sugar to make 1.5 batches of muffins.  If one batch of muffins requires 1/4 cup of sugar, you can think of the amount of sugar needed being 1/4 cup per batch.  That being said multiply 1.5 batches by 1/4 cup per batch to find cups of sugar.
(1.5 batches)x((1/4 cups)/(1 batch))=0.375 cups of sugar.

You can also think of it as if one batch takes 1/4 cup of sugar, half of a batch would take 1/8 cup of sugar.  Since 1.5 batches is just 1 batch+1/2 batch, you can say the amount of sugar needed is 1/4 cup+1/8 cup which equals 3/8 cup sugar.

I hope this helps you.
