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

x=13 feet

Step-by-step explanation:

A ramp is between 1.96 and 1.80 feet, we will take 1.96

and R(x)=1.96 feet: we apply quadratic formula; , where a=-0.05, b=0.8 and c=-1.96, so

solving ; we take the highest value of x, x=13

me

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
