The opening course of the dog olympics involves the dogs running over a parabolic

ramp. the quadratic equation, r(x) = -0.05x2 +0.8x, models the ramp, where x is

the horizontal distance, in feet, of the ramp, and r(x) represents the height of the

ramp, in feet

according to the model, what is the horizontal distance of the ramp? enter your

answer in the box below

feet

Add 1/7 + -1/7 your answer should be reduced to its smallest form and should not be an improper fraction

Another type of subtraction equation is 16-b=7. explain how you would sole this equation then solve it.

Ascientist has discovered an organism that produces five offspring exactly one hour after its own birth, and then goes on to live for one week without producing any additional offspring. each replicated organism also replicates at the same rate. at hour one, there is one organism. at hour two, there are five more organisms. how many total organisms are there at hour seven? 2,801 19,531 19,607 97.655
