Scientists have steadily increased the amount of grain that farms can produce each year. The yield for farms in France is given by y=−2.73x^2+11000x−11000000 where x is the year and y is the grain yield in kilograms per hectare (kg/ha). What does the y-intercept of this function represent?

A. the increase in crop yield every year

B. the crop yield in year zero

C. the crop yield for a given year

D. the crop yield in 1960

i hope this : )

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
