The center of a hyperbola is (−4,3) , and one vertex is (−4,7) . The slope of one of the asymptotes is 2.

Monica [59]

Answer:

The answer to your question is below

Step-by-step explanation:

C (-4, 3)

V (-4, 7)

asymptotes = 2 = $\frac{b}{a}$

- This is a vertical hyperbola, the equation is

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

slope = 2

a is the distance from the center to the vertex = 4

b = 2(4) = 8

$\frac{(y - 3)^{2} }{4^{2} } + \frac{(x + 4)^{2} }{8^{2} } = 1$

$\frac{(y - 3)^{2} }{16} + \frac{(x + 4)^{2} }{64} = 1$

Find the value of the variable What is x?

yaroslaw [1]

Answer:

x = 7

Step-by-step explanation:

I think there may be other ways to do this ... but this is one I guess....

one angle= 90 ( given)

the other = 45 (given)

the third = 90 + 45 + a = 180

(all angles of triangles is 180 [angle sum property])

a = 180 - 135

= 45

The base angles are equal so that means it is a isoscles triangle. In isoscles triangle, two sides are equal , so

if one side is 7

the x is 7 too

(as it cant be the hypothenus)

I think this is right
