What slope is perpendicular to m= 5/8 m=-5/8 m=5/8 m=-8/5 m=8/5

MrRa [10]

Answer:

C) $m =\frac{-8}{5}$

The slope of the perpendicular line $m =\frac{-8}{5}$

Step-by-step explanation:

Explanation:-

Given that the slope of the given line is

$m =\frac{5}{8}$

The slope of the perpendicular line

= $\frac{-1}{m}$

The slope of the perpendicular line

= $\frac{-1}{\frac{5}{8} }$

Final answer

The slope of the perpendicular line

$m =\frac{-8}{5}$

This hyperbola is centered at theorigin. Find its equation.Foci: (-2,0) and (2,0)Vertices: (-1,0) and (1,0)

beks73 [17]

SOLUTION

From the question, the center of the hyperbola is

$\begin{gathered} (h,k),\text{ which is } \\ (0,0) \end{gathered}$

a is the distance between the center to vertex, which is -1 or 1, and

c is the distance between the center to foci, which is -2 or 2.

b is given as

$\begin{gathered} b^2=c^2-a^2 \\ b^2=2^2-1^2 \\ b=\sqrt[]{3} \end{gathered}$

But equation of a hyperbola is given as

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

Substituting the values of a, b, h and k, we have

$\begin{gathered} \frac{(x-0)^2}{1^2}-\frac{(y-0)^2}{\sqrt[]{3}^2}=1 \\ \frac{x^2}{1}-\frac{y^2}{3}=1 \end{gathered}$

Hence the answer is

$\frac{x^2}{1}-\frac{y^2}{3}=1$
