MODELING WITH MATHEMATICS The arch support of a bridge can be modeled by $y=-0.0012x^2$ , where $x$ and $y$ are measured in feet. Find the height and width of the arch.

The arch support of a bridge is parabolic in shape. The parabola is graphed on a coordinate plane. The x-axis is extended from negative 550 to 550, in increments of 50. The y-axis is extended from negative 400 to 75, in increments of 25. The parabola opens downward with the vertex lying at ordered pair 0 comma 0. It is drawn through the points at ordered pair negative 300 comma negative 100 and ordered pair 300 comma negative 100.

The arch is
feet high and
feet wide.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

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.
