A train is traveling at a constant speed and goes 7.5 kilometes in 6 minutes how far does it go in 100 minutes???

125 km

Step-by-step explanation:

We are told the train goes 7.5 kilometres in 6 minutes.

So, distance = 7.5 km and time = 6 minutes.

Now, speed is given by;

Speed = distance/time

Speed = 7.5/6

Speed = 1.25 km/min

Now, to find how far it goes in 100 minutes, we will just plug in speed = 1.25 km/min and time = 100 minutes into the speed equation above.

Thus;

1.25 = distance/100

Distance = 1.25 × 100

Distance = 125 km

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
