Jess and Wes used to race each other when they were younger. Jess could cover 8
marshall27 [118]

Answer:

160 meters

Step-by-step explanation:

Let call dj  distance run by  Jess    and   dw  distance run by Wes

By Jess courtesy Wes will be  60 meters ahead of Jess

Let call t the time in which both runners are at the same point, which in fact is when both distances are equal

dj  =  8 m/sec * t        and    dw  =  60  +  5 m/sec * t

Then we make  dj = dw

8*t  =  60 + 5*t

3*t  =  60

t = 20 sec

Now passed 20 sec  dj   =   8 * 20   = 160 m

and   dw = 60 + 5*20   dw  =  160 m

What is the focal length of the parabola with equation shown below?
GuDViN [60]
Patterns:  vertical : y = a(x - h)² + k          horizontal: x = a(y - k)² + h

Look at the patterns above and remember these key points.

<span>1) if the x is squared, the parabola is vertical. It either opens up or down. </span>
    if the y is squared, the parabola is horizontal. It either opens left or right.

2) if a is positive, the parabola opens up or to the right.
    if a is negative, the parabola opens down or to the left

<span>3) the vertex is at (h,k). Be very careful. locations of h and k varies if the parabola is vertical or horizontal. its sign is also different in those positions</span>
