Step-by-step explanation:
I took this quiz and got it right.
The correct answer is beginning at 5 ounces, the graph is discontinuous every 5th integer of the domain.
It is a step function; there is not a continuous increase between values. The shipping level is fixed for each price, then jumps to the next tier. This will be a discontinuous graph.
If I think I’m understanding it, the new members out of the 200 original would be adding 28% to the mix
Speed traveling west = x - 10 km /hr
275 / ( x-10) - 300 / x = 1/2
275 *2x - 300 (x-10)*2 = ( x-10) *x
550x - 600x +6000 = x^2 -10x
x^2 +40x - 6000 = 0
( x -60) ( x+100) = 0
x = 60
ANSWER East = 60 km/ hr West = 50 km /hr
CHECK
300 /60 = 5 hours
275 /50 = 5.5 hours
