A bridge is sketched in the coordinate plane as a parabola represented by the equation h=40-0.01x2, where h refers to the height
ElenaW [278]

Answer:

The length of the bridge is 126.492 feet.

Step-by-step explanation:

Let h(x) = 40-0.01\cdot x^{2}, where x is the position from the middle of the bridge, measured in feet, and h(x) is the height of the bridge at a location of x feet, measured in feet. In this case, the length of the bridge is represented by the distance between the x-intercepts of the parabola, which we now find by factorization:

40-0.01\cdot x^{2} = 0 (Eq. 1)

x^{2} = \frac{40}{0.01}

x =\pm \sqrt{\frac{40}{0.01} }

x = \pm 63.246\,ft

Given that the parabola is symmetrical with respect to y-axis, then the length is two times the magnitude of the value found above, that is:

l = 2\cdot (63.246\,ft)

l = 126.492\,ft

The length of the bridge is 126.492 feet.

x=y

x^2+x^2 = 9*30

2x^2 = 270

x^2 = 9*15

x = y = 3√15

Describe how to determine which side of the boundary line should be shaded
iogann1982 [59]
Hello Bri,

If you are talking about a boundary line on a coordinate plane, the best way to determine which side to shade is to start by selecting a coordinate point (x, y) that is not on the line.

Then, substitute those values into your inequality. Simplify the inequality. If the resulting statement is true, then shade the side with your point. If the resulting statement is false, then shade the other side.

Testing a point like this shows the side of the inequality that is the solution and needs to be shaded.

Good luck!
