The parabolic arch of a bridge over a one-way road can be described by the equation y = -x^2 + 6, where x and y ar emeasured in
Vladimir [108]
So check the picture below

if we check the solutions or zeros for the equation, we get \bf y=-x^2+6\implies 0=-x^2+6\implies x=\pm \sqrt{6}

and as you can see in the picture, the value of "x" when y = 3.5, or the height of the truck is  \bf y=-x^2+6\implies 3.5=-x^2+6\implies x=\pm \sqrt{2.5}

the truck, ends up with a clearance of \bf \sqrt{2.5}-1.5 on either side, so, the maximum clearance, the truck can have, those two clearances added together, \bf 2(\sqrt{2.5}-1.5)

Find the equation of the line.
hoa [83]

Answer:

y=3x+3

Step-by-step explanation:

To find the slope, find two points and use the rise over run.

Some points you can use are (0, 3) and (1, 6)

The rise is 3 and the run is 1.

3/1 = 1.

The slope is 3.

To find the y-intercept, find the point where x = 0.

(0, 3)

The y-intercept is 3.

Now you can write an equation.

y=mx+b

m is the slope and b is the y-intercept.

y=3x+3
