The equation y=−0.065x2+6.875x+6200 models the amount y of sugar (in pounds per square foot) produced where x is the amount of fertilizer (in pounds per square foot) used. what is the best approximate for the amount of sugar produced when 3 pounds per square foot of fertilizer is used? 6200 lb/ft2 6210 lb/ft2 6220 lb/ft2 6230 lb/ft2

Answer : 6220 lb/ft2

y=

Where y is the amount of sugar (in pounds per square foot) and

x is the amount of fertilizer (in pounds per square foot)

We need to find the amount of sugar produced when 3 pounds per square foot of fertilizer is used.

We plug in 3 for x and find out y

y=

y=

y = -0.585 + 20.625 + 6200 = 6220.04

6220 lb/ft2 is the amount of sugar produced.

the answer will be b x² +x-1

step-by-step explanation:

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
