Find the polar equation of the conic with focus at the pole, directrix y=3, and eccentricity of 2

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
