The center of a hyperbola is located at the origin. One focus is located at (0,20), and its associated directrix is
represented by the line y = -256/20. What is the equation of the hyperbola?
O y^2/16^2 - x^2/20^2 = 1 O y^2/12^2 - x^2/16^2 = 1 O y^2/20^2 - x^2/12^2 = 1 O y^2/16^2 - x^2/12^2 = 1

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

but which class are u may know that first

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
