Okay! Math isn't my strongest subject. However, though, I think the answer is 25.

Convert the function into intercept form. Show your work. y=-x^2+5x+36

UkoKoshka [18]

Y = -x2 + 5x + 36 → y = -(x2 -5x -36)

→ y = -(x2 - 9x +4x - 36)

→ y = -[x(x-9) + 4(x - 9)]

→ y = -(x - 9)(x + 4)

Your answer would be y=-(x-9)(x+4).

Which equation represents the hyperbola shown in the graph? A. x-3^2/64-y-1^2/36=1 B. x+3^2/64-y+1^2/36=1 C. y+1^2/64 - x+3^2/36

Leokris [45]

Answer:

C. (y + 3)²/64 - (x + 1)²/36 = 1

Step-by-step explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo

My answer:

From the photo, the given information is:

The vertex : (−1, 5).

The center is (−1, −3).

As we know, the hyperbola has general equation for it is:

$\frac{(y-k)^{2} }{a^{2}}-\frac{(x-h)^{2} }{b^{2}}=1$

where h and k are the coordinate for the center (h, k) and we only needed the center of the hyperbola to find our answer.

In this situation, we have:

$\frac{(y-(-3))^{2} }{a^{2}}-\frac{(x-(-1))^{2} }{b^{2}}=1\\\frac{(y+3)^{2} }{a^{2}}-\frac{(x+1)^{2} }{b^{2}}=1$

Hence, we choose C.

Hope it will find you well.
