CASE 1
1560(1)2+23400
1 = (12 + 45)2
= 104 u + 1560 + 23400
= (42)2
= 104 1 + 5
2+45 2460
2 = 2116
= 104 + 504 = 520 2 +( 2+45)(520) = 11.80
2+45 ( 2+45)2
1560(2)2+23400
= 520 = 1040 2+520 2+23400 2 = (22 + 45)2

SUMMARY/CONCLUSION
Considering all of facts, in case 1, we able to identify the initial population of
algae,N. Then, using the formula: = ( + + ) , =population of algae and
=time in hour, we able to determine the groeth of algae in 8 to 10 hours. In
case 2, using the formula: = − + + , =population of virus
while =time in hour, we can state either it is minimum or maximum, and draw
the graph to demonstrate the growth of algae
