Answer:

400 ft

Step-by-step explanation:

Let the distance traveled = d

Let the time taken = t

d α t^2

d = kt^2

k = d /t^2

When d = 100 and t = 2.5secs

k = 100/ (2.5)^2

k = 16

d = 16t^2

When t = 5secs

d = 16(5)^2

d = 16 * 25

d = 400 ft

KatRina [158]

Answer: The graph of line y= 200+25x represents the given situation.

Step-by-step explanation:

Here, y represents the total calories he takes while x represents ounces of fruit smoothies with his cereal.

And, He knows that a bowl of his favorite cereal with milk has 200 calories.

Also, He also likes to drink a fruit smoothie with his cereal where Each ounce of the smoothie adds 25 calories.

Therefore, y = 200+ 25x  is the total calories he takes after drinking the x ounces  fruit smoothie with his cereal.

The x- intercept of the above line = (-8,0)

And, y-intercept = (0,200)

If x= 1 y=225

If x=-1 y= 175

Therefore, (1,225) and (-1,175) are the point of the above lines

Thus, with help of above information we can plot the graph of line y = 200+ 25x.
