Use factorisation to simplify the following expression (x^2-9)/(x^2-4x+3)

we simplify the top and bottom of the fraction separately. x^2-9 factorises to (x+3)(x-3) using the difference of two squares.x^2-4x+3 factorises to (x-1)(x-3). So the above formula simplifies to (x+3)/(x-1)

A baseball player strikes a ball with an initial velocity of 43ms^-1 at an angle of 32° to the horizontal. How far does the ball travel horizontally in 4 seconds?

Since the Initial velocity has a direction that is 32° to the horizontal we can split the velocity into it's components. The horizontal component of the velocity is v x = 43cos(32) (m/s). Since distance = ve...
