To the lovers of math: challenge :
a company manufactures high-powered fountains that can be used to create elaborate water shows set to light and music. the company makes three models of
fountains, each of which can launch a vertical stream of water to a different height, as indicated in the table below. model a model b model c
height 77 100 240
time to fall (s) 2.194,
initial velocity 70.2 , 123.9
complete the following tasks, filling in the missing values in the table as you find them: (1)find the time water would take to fall from each height in the table back to its starting level.(2)find the initial upward velocity required for fountain b to launch the water to its maximum height(3)create a function that will give you the minimum initial upward velocity ,v ,required to launch water to any given height , h. you

I am only in the seventh grade so it might not be right, but this is what I would do:

Set up a proportion: 77/2.194/70.2 = 100/x/y = 240/z/123.9

Then solve for x: if 77 equals 100, that means 2.194 is 77% of x. So x equals 2.849350649

*the 350649 repeats

Then solve for y: Like mentioned before 70.2 is going to only be 77% of y, so if you set that up in a proportion, it is: 70.2/77 = y/100. So when you solve you get 91.16883116883117...

Then finally we solve for z: 100 is only 41.6% of 240, so that means 2.849350649 is only 41.6% of z. So then we set it up as a proportion: 141.6/100 = z/2.849350649, then we solve. It equals 4.034680518984.

Sorry if my answer was redundant, but hope this helped!

step-by-step explanation:

i think you should think about the question and not look online.
