Hi there, I finished my unit of calculus called "derivatives." Below are just two questions I was confused on from our review package. Thank you so much :)

Question 1:

Han Solo is moving from left to right along the curve ? = ?^2 while orbiting the planet of Tatooine. He wants to shut off the engines of the Millenium Falcon at a certain point, so that he will go off along the tangent line and land. At what point should he shut off the engines in order to reach the landing point (4, 15)?

Queston 2:

Find the derivative of

\fSuppose at point (m,n) the shut off the engines, in A andere to reach the landing point (4,15) Look a above the graph mmust be less than 4 (le m
