Recall from lesson 6 that the semi-major axes of an ellipse are the segments from the center to the farthest
vertices, and the semi-minor axes are the segments from the center to the closest vertices. for each of the ellipses
in problem 1, find the lengths a and b of the semi-major axes.

answer:

an ellipse is "the set of all points in a plane such that the sum of the distances from two fixed points (foci) is constant".

step-by-step explanation:

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
