Question

M(t) models the distance (in millions of km) from Mars to the Sun t days after it's at its furthest point.M(t) = 21 cos270687+ 228What does the solution set for 240 = 21 cos211mut687+ 228 represent?

Answer 1

The solution set of the equation will give the days when mars is at 240 million km from the earth.

Therefore the answer is A.
