The path of a snowboarder performing stunts is given by the equation ft=-16(t-2)(t+1), where t is time in seconds and y is the duration of the stunt. Graph the function. What are the x-intercepts? Explain the meaning of the x-intercepts in the context of the problem. How long does the stunt last?

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

-1/2 +2

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
