What is this function written in vertex form? f(x) = (x –1)2 – 7 f(x) = (x 1)2 – 7 f(x) = (x –1)2 – 5 f(x) = (x 1)2 – 5
Maslowich

The vertex form of all expressions is given below.

We have given that the expressions

We have to write the function in vertex form.

<h3>What is the vertex form of the equation?</h3>

The vertex form of a quadratic function is given by f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.

Therefore the first equation

f(x)=(x-1)^2-7

it can be written as

f(x)=1(x-1)^2+(-7)

The second equation can be written as

f(x) = (x+1)^2 -7

vertex for is,

f(x)=1(x-(-1))^2+(-7)

The third equation is,

f(x) = (x -1)^2 - 5

Vertex form is,

f(x)=1(x-1)^2+(-5)

Forth equation is,

f(x) = (x +1)^2 +(- 5)

Vertex form is,

f(x) =1 (x -(-1))^2 +(- 5)

Edison has a sales job and receives $45,448 as his annual pay, plus commission. His company pays him a commission of 15% on his
11111nata11111 [884]

Answer:

Edison will be paid $15,112 for 3 months

Step-by-step explanation:

Edison receives an annual fixed pay = $45,448.

Monthly pay  = 45,448/12 = $3787.33

3-month salary = $3787.33 *3 = $11.362

Commission = 15%

Total sale = $25,000 for the first 3 months.

Commission amount = 25,000*0.15 = $3750

Therefore, total pay that Edison received during first 3 months= salary + commission

= $11,362 + $3750

= $15,112

Thank you.

What would be the volume of the cone that has the same measurement as the cylinder above in the pic
fomenos

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

Volume of cone will be ~

\fbox \colorbox{black}{ \colorbox{white}{volume} \:  \:  \:   \:   \: \colorbox{white}{=}  \:  \:   \:   + \colorbox{white}{462 \: cm³ }}

\large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}

Let's find the volume of cone with ~

  • radius (r) = 7 cm

  • height (h) = 9 cm

And as we know, volume of cone is equal to ~

  • \dfrac{1}{3}\pi  {r}^{2} h

now, let's plug in the values and find the volume ~

  • \dfrac{1}{ \cancel{3}  }\times  \dfrac{22}{\cancel{7}}  \times \cancel{7 }\times 7 \times \cancel{9}

  • 1 \times 22 \times 7 \times 3

  • 462 \:  \:  {cm}^{3}

Volume of cone is 462 cm³ = 462 ml
