Rocky lends 3000 dollars to ken at 10% per annum and the ken lends the same sum to mike at 12% per annum find kens gain over a period of 3 years?

3(2x-3) < x+1

According to the laws of physics, if a ball travels along a line with slope m and strikes the side of the pool table, it bounces back along a line with slope –m.

a. A ball starts at (2, 6) and moves along the line with slope -2 towards the y-axis. Where does it strike the y-axis? What slope does it have after bouncing off the y-axis? Draw the paths on your graph. Give the equations for both parts of the path of the ball.

b. Follow the ball in (a) for two more bounces, drawing the lines on your graph. Give the coordinates of the points where the ball bounces off each side. State the slope of each part of the path. If the ball could move according to these rules forever, would it ever go in a pocket?

I have a box of nickels and dimes. When I counted the money, I was surprised to see that I have exactly
$10. Then it occurred to me that if my nickels were dimes and my dimes were quarters, I would have
$21.25. How many dimes and nickels are in my box?

What is the domain of f/g? if f(x) = x^2-4x-5 and g(x)=x-5

What is h *g when h = x+1/x-1 and g is x-5

1. On graph paper, draw the axes, and the lines y = 12 and x = 6. The rectangle bounded by the axes and these two lines is a pool table with pockets in the four corners. According to the laws of physics, if a ball travels along a line with slope m and strikes the side of the table, it bounces back along a line with slope –m.

Determine what the amount of money in a money market account providing an annual rate of 7% compounded daily if George invested $2500 and left it in the account for 10 years.

(cos2.cos3A - cos^2A.cos7A + cosA.cos10A)/(sin4A.sin3A - sin2A.sin5A + sin4A.sin7A) = cot6A.cot5A'
