Answer:

a = 2

y = 2(x-3) ^ 2 +6

Step-by-step explanation:

We have the following quadratic equation in vertex form:

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

Where x = h is the vertex of the parabola.

They give us the vertice:

(3, 6)

So:

h = 3\\k = 6

Therefore the equation is of the form:

y = a(x-3) ^ 2 +6

Now we need to find the value of a.

We have another point that belongs to the equation: (4, 8)

Then we substitute the values in the equation and clear a.

8 = a(4-3) ^ 2 +6\\\\8 - 6 = a\\\\a = 2.

Finally the equation is:

y = 2(x-3) ^ 2 +6

Answer:

a = 2

Step-by-step explanation:

The vertex form y = a(x - h)^2 + k

Where (h, k) is the vertex.

Given: (h, k) = (3, 6) and point (4, 8)

Now plug in the given values and find the value of "a"

x =4 and y = 8

8 = a(4 - 3)^2 + 6

8 = a(1)^2 + 6

8 = a + 6

a = 8 - 6

a = 2

So the value of a = 2.

Hope you will understand the concept.

Thank you.

 Convert 10% to .1, (10 divided by 100)
 then multiply 40 times .1
then subtract 4 by 40

If P= (-6,4) find Ry= -x (P)
julsineya [31]

The value of Ry= -x (P) is P' = (4, 6)

<h3>How to determine the transformation?</h3>

The point is given as:

P = (-6, 4)

The transformation Ry= -x (P) means tha:

(x, y) = (y, -x)

So, we have:

P' = (4, 6)

Hence, the value of Ry= -x (P) is P' = (4, 6)
