Question

For a skateboard halfpipe shaped like a parabola and using the ground as the x-axis, where should the base of the halfpipe be positioned?

a) (0, 20); y = x^2 + 20x + 100
b) (0, 20); y = x^2 - 20x + 100
c) (0, 10); y = y - 20x + 100
d) (0, 10); y = y^2 - 1040 + x^2 - 1

Answer 1

The base of the halfpipe should be positioned at (0, 20); y = x^2 - 20x + 100. Hence the correct answer is option B

Step-by-step explanation:

The equation that represents the shape of a skateboard halfpipe is a parabola. To determine where the base of the halfpipe should be positioned, we need to identify the equation that describes the parabola. The correct equation is option b) (0, 20); y = x^2 - 20x + 100.
