Answer:

C: 5 inches

Step-by-step explanation:

The length of the sides of the new square is the square root of the area:

s = √A = √49 = 7

The original square had sides 2 inches shorter, so they were ...

7 in -2 in = 5 in . . . . side length of original square

you move first the number without the variable to the other side with the opposite sign

-0.75p=0.25+2

-0.75p=2.25

then as -0.75 is multiplying you pass it to the other side dividing

The vertex of the parabola below is at the point (2, 4), and the point (3, 6) is on the parabola. what is the equation of the pa

Paraphin [41]

Given:

Vertex ===> (h, k) (2, 4)

The parabola passes through the point: (x, y) ==> (3, 6)

Let's find the equation of a parabola.

To find the equation, use the general equation of a parabola with vertex (h, k):

$y=a(x-h)^2+k_{}$

Where:

(h, k) ==> (2, 4)

(x, y) ==> (3, 6)

Substitute values into the general equation:

$\begin{gathered} 6=a(3-2)^2+4 \\ \\ 6=a(1)^2+4 \\ \\ 6=a+4 \end{gathered}$

Subtract 4 from both sides:

$\begin{gathered} 6-4=a+4-4 \\ \\ 2=a \\ \\ a=2 \end{gathered}$

Substitute 2 for a, and input the values of the vertex (h, k) in the general vertex equation:

$y=2(x-2)^2+4$

Therefore, the equation of the parabola is:

$y=2(x-2)^2+4$

ANSWER:

$y=2(x-2)^2+4$
