The orbit of the planet Pluto is and ellipse with the sun at one focus. The maximum distance between the sun and Pluto is 7,375 km, and the minimum distance is is 4,425 km. How far (in millions of km) is it across Pluto's orbit at its widest point?
a) 5,900
b) 11,425
c) 11,800
d) 5,712.65

Best ResponseYou've already chosen the best response.0I guess Pluto's furthest orbit form the sun. I'm not 100% sure, that's all the question says.

Best ResponseYou've already chosen the best response.0if u draw an ellipse then the point of maximum distance from one of the focus would be the farthest point on orbit

Best ResponseYou've already chosen the best response.0let it be \[{x ^{2}/a ^{2}} + y ^{2}/b ^{2} =1\] b^2=a^2(1e^2) e is ur coeff of eccentricity foci are at (ae,0) and (ae,0) see a general diagram of ellipse a+ae=maximum distance from focus=7375 aae=min dist from focus=4425 find a , e

Best ResponseYou've already chosen the best response.0yes whats your equation with that e thingy , thats cool, for any conic

Best ResponseYou've already chosen the best response.0e is called ur coefficient of eccentricity that equation is only for an elliptical path

Best ResponseYou've already chosen the best response.0This is an elliptical path though. What is the foci?

Best ResponseYou've already chosen the best response.0I mean what does it represent? Like a definition.

Best ResponseYou've already chosen the best response.0foci are the two points on the major axis of the ellipse An ellipse can be drawn using two drawing pins, a length of string, and a pencil: Push the pins into the paper at two points, which will become the ellipse's FOCI. Tie the string into a loose loop around the two pins. Pull the loop taut with the pen's tip, so as to form a triangle. Move the pen around, while keeping the string taut, and its tip will trace out an ellipse.

Best ResponseYou've already chosen the best response.0That's a very interesting way to draw an ellipse, never heard of that technique, Thank you. Now in solving this problem, what do I need to plug into your equation to come up with numbers?

Best ResponseYou've already chosen the best response.0try to visualize it sun is at (ae,0) one of the foci max distance would be when pluto is at (a,0) so, a+ae=7375 work out for min distance in the same way

Best ResponseYou've already chosen the best response.0Would it be either a+ae=4,425 or aae=4,425?

Best ResponseYou've already chosen the best response.0what did u do to find the widest point??

anonymous

Best ResponseYou've already chosen the best response.0I'm not sure if it's right. But i think this is a question that's easier than you would think. You want to find the widest point, so all I did was add 7,375 and 4,425 and that gives you 11,800.
