if the equation of a parabola is y = 7(x-4)^2+v and its vertex is (4,-2) , what is the value of v in the equation
N76 [4]
The vertex form of a quadratic function: y = a(x - h)² + k

vertex (h; k)

We have: y = 7(x - 4)² + v
vertex: (4; -2)

therefore: v = -2

Consider the function f(x)=−2/3x+5 .
Arturiano [62]

Answer:

\frac{14}{3}

Step-by-step explanation:

To evaluate substitute x = \frac{1}{2} into f(x)

f(\frac{1}{2}) = - \frac{2}{3} × \frac{1}{2} + 5

                                  = - \frac{1}{3} + \frac{15}{3} = \frac{14}{3}

What are the coordinates of R' for the dilation D(0.5. p)(PQRS)?
11111nata11111 [884]

Answer:

R' = (-1,-0.5)

Step-by-step explanation:

See attachment for complete question.

From the attachment:

P = (-3,-3)

R = (1,2)

Dilation:

D_{(0.5,P)}

Required

Determine R'

First, subtract the coordinates of P from R. This means that R is measured from P.

R = (1-(-3),2-(-3))

R = (1+3,2+3)

R = (4,5)

Next, apply dilation factor 0.5

R' = R * 0.5

R' = (4,5) * 0.5

R' = (4* 0.5,5* 0.5)

R' = (2,2.5)

Lastly, measure R' from the origin by adding the coordinates of P to R'

R' = (2+(-3),2.5+(-3))

R' = (2-3,2.5-3)

R' = (-1,-0.5)
