Y=Mx+b
Rise / run between any two points = slope (m)
Where the line crosses the y axis is (yint) (b)
Slope is -1/2
Yint = -8
So the equation is y=(-1/2)x - 8
Answer:
B the dirty shades, the rickety chairs, the threadbare rugs
<span>y=
-0.000475x^2 + 0.851x
How high above is the
river bridge (the top of the arch)?
You have to find the vertex of of the parabole: the y-coordinate is the highest point.
Remember that the x-coordinate of the vertex of a parabole is at - b / 2a.
That is x = - 0.851 / [ 2(-0.000475) = 895.79
The corresponden y is y = </span><span>-0.000475(895.79)^2 + 0.851(895.79) = 381.16 feet above the river.
How long is section of bridge above
the arch?
The section of the brige is equal to the difference of the two roots
Roots: </span><span>y=
-0.000475x^2 + 0.851x = 0
=> x( - 0.000475x + 0.851) = 0
=> x = 0 and x = 0.851 / 0.000475 = 1791.58
Then the section is 1791.58 feet long.
Therefore, the answer is the option </span><span>D)The bridge is about 381.16 ft. above the river, and the length of the bridge above the arch is about 1,791.58 ft
