Elizabeth and Markus are playing catch. Elizabeth throws the ball first. The height of the ball can be modeled by the equation h = −2t(t − 5), where h is the height of the ball in feet and t is the time in seconds. Markus is distracted at the last minute and looks away. The ball lands at his feet. If the ball travels at a rate of 3.5 feet per second, how far is Markus standing from Elizabeth when the ball hits the ground? Markus is standing ___ feet away from Elizabeth when the ball hits the ground.

step-by-step explanation:

here's a poem i finished a while ago. i hope you like it and that it inspires you.

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
