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 midpoint of the segment with the following endpoints.<br> (10,3) and (2,9)

Anastaziya [24]

Answer:

(6,6)

Step-by-step explanation:

To find the x coordinate of the midpoint take the average of the x coordinates of the endpoints

(10+2)/2 = 12/2 = 6

To find the y coordinate of the midpoint take the average of the y coordinates of the endpoints

(3+9)/2 = 12/2 = 6
