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

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
