- three grams of a radio active isotope decay in two weeks to 0.9 grams .Determine both the half life and constant of proportionality [8mks]
- using the artificial variable technique solve
Min Z=5x1+3x2
subject to
2x1+4x2 less than or equal to12
2x1+2x2 =10
5x1+2x2 greater than or equal to 10
and x1=x2 greater than or equal to zero.
write the above in standard using mathematical approach.
4.a conservative investor has 100000 dollars to invest ,the investor has decided to use three ways for generating income ,municipal bonds

2.the proportion allocated to money markets account should be at least double the amount on certificate deposit
the annual return will be 8% on bonds ,9% on certificate of deposit ,7% on money markets .Assume the entire amount will be invested .formulate the linear programing
model ignoring any transaction cost and the potential of different investment lines
explain and develop a linear programming model of the above ?
