A bridge is sketched in the coordinate plane as a parabola represented by the equation , where refers to the height, in feet, of the bridge at a location of
feet from the middle of the bridge. The bridge starts and ends at the x-intercepts of the parabola.
What is the length of this bridge?

Do not round your answer until your end result. When finding the length of the bridge round to the nearest tenth of a foot. n

hello i am doing good for you that it's summer in your country or state ; )

btw in my country we just have sun and rain as (because i live in the caribbean lol)

also, thx a lot for the points : )

probably .5

i can on others if necessary.

none.

step-by-step explanation:

m

1

=

5

m1=5

b

=

−

1

b=-1

find the slope and y-intercept of the second equation.

m

0

m2=0

b

=

−

6

b=-6

compare the slopes

m

m of the two equations.

m

=

5

,

m

2

=

0

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
