Use the graph to write and equation for each conic section. .

Question #5:  The center of this ellipse is (4,2).  The ellipse is vertically oriented.  What is the distance (a) from the center (4,2) to the upper vertex of the ellipse?  What is the distance (b) from the center (4,2) to the right hand vertex of the ellipse?

The equation of this ellipse is

(y-4)^2      (x-4)^2
 +   = 1, where (a and b are determined above).
    a^2           b^2

On monday,mrs.wise bought 3 lbs of apples at $4per lb= 4*3=$12on tuesday ,20%off and she buy 5 lbs of apples = $4-20%=3.20*5lb=$16example: other wise when she buy 5lbs on monday she have to spend 4*5=20

These are the multiples of 15 but what you are probably asking or what are the factors of 15
