A slingshot stores energy in the stretched elastic band when it is pulled back. The amount of stored energy versus the pull length is approximately parabolic. Refer to this graph of the stored energy in millijoules versus pull length in centimeters. Determine the function, E(d), that describes this plot.

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

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
