The hurdle and runner form a right triangle (see attached picture) such that

sin(30°) = <em>h</em> / (5 ft)

and

cos(30°) = <em>x</em> / (5 ft)

where <em>h</em> is the height of the hurdle and <em>x</em> is the horizontal distance from where the runner jumps to the hurdle. So

<em>h</em> = (5 ft) sin(30°) = 5/2 ft = 2.5 ft

<em>x</em> = (5 ft) cos(30°) = (5√3)/2 ft ≈ 4.33 ft

Consider the equation y = 4.2x and the table below that represents this relationship. X= 0, 2, 4, 6, Y= 0, 8.4, 16.8, 25.2
enyata [817]
Please present the relationship in a table arranged vertically:

<span>this relationship. X= 0, 2, 4, 6, Y= 0, 8.4, 16.8, 25.2   becomes:

</span><span> x        y
---    -----
 0       0
 2      8.4
 4     16.8
 6     25.2

Notice that as x increases by 2 units from 2 to 4, y increases by 8.4 units to 16.8.  Thus, the slope of this line is 
        16.8
m = -------- = 8.4
          4-2

Your problem statement sounds incomplete; what were you asked to do here?

You could compare the equations of the 2 functions:

y = 4.2x and
y = 8.4x 

The slope of the 2nd function is twice that of the first function.  Both graphs go through the origin, (0,0).</span>
