1)Suppose $6000 is invested with 3.5% interest for 4 yr under the following compounding options. Complete the table.

Compounding Option I # compoundings per year I Result

a. Daily I I

b. Continuously I I

2)Find AB, if possible.

A = (4 5 7 )

(8 8 0)

and

B = (8 8)

( 3 -7)

(9 -7)

3)Evaluate the determinant of the given matrix

A = (5 -9)

( 2 -4)

4) Solve the system by using Cramer's rule. (

-5x + 15y + 5z = -7

10x + 25y = -14

15x + 5y - 10z = 7
