Let d equal the distance in meters and t equal the time in seconds which is a direct variation equation for this relationship

Step-by-step explanation:

we know that

A relationship between two variables, t, and d, represent a proportional variation if it can be expressed in the form or

Let

d -----> the distance in meters

t -----> the time in seconds

The direct variation equation is equal to

where

k is the constant of proportionality

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  . 

step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
