An investment banker received a bonus and invested that money in two investments. He put a certain sum of money in the first investment that returned 11% interest after one year. In the second investment he
invested four times that of the first investment and got a 15% interest return after one year. If the total
interest from his investments after one year was $9,230.00, find the amount invested at each interest rate.
at 11% interest (if needed, round to the nearest cent

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
