Michael invested s1800 into an account that pays 496 interest, compounded annually. what is
the balance in his account after 2 years?

Balance after 2 years=2,792

Step-by-step explanation:

To calculate the total amount Michael will have after 2 years, we can express this as;

Total amount=Initial investment+Annual interest

For the first year;

Initial investment=1800

Annual interest=496

replacing;

Total amount=(1,800+496)=2,296

For the second year;

Initial investment=2,296

Annual interest=496

replacing;

Total amount after 2 years=(2,296+496)=2,792

Balance after 2 years=2,792

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
