HELP I NEED TO SHOW MY WORK FOR THIS QUESTION!! The major axis of the
ellipse below has
length of 13. If the
solid line has length
10, what is the length
of the dashed line?

3

Step-by-step explanation:

The distance from one focus, to any point on the ellipse and then to the other focus = length of major axis

So, 10 + dashed line = 13

Therefore, dashed line = 13 - 10 = 3

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.

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
