Phil is riding his bike. He rides 50 miles in 4 hours, 625 miles in 5 hours, and 75 miles in 6 hours. Find the constant of proportionality and write an equation to describe the situation. Let x represent the number of
hours.
The constant of proportionality is k =
The equation that describes the relationship is y =

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
