The equations of motion for constant acceleration are obtained from Newton's laws of motion. They are sometimes known as the SUVAT equations and can be used to calculate components of a projectile's motio...

i.) 5/20 * 15/20 *100 = 18.755%ii.) Since 3 have to be on the team, essentially the problem is percentage chance of one female getting onto a team of 12, therefore 2/17 * 12/17 * 100 = 8.30%

f^-1(x) = inverseSet f^-1(x) as y = (2x+3)/(x-4)y(x-4) = 2x+3yx-4y = 2x+3yx-2x = 3+4yx(y-2) = 3+4yx = (3+4y)/(y-2)f^-1(x) = (3+4x)/(x-2)

Conduction, Convection, Radiation
Roof: Insulation. Material reduces conduction as it is a greater inductor of heat than air. Material reduces convection currents as the air gaps are now too small fo...

Factorising the left hand side of the inequality gives (x-2)(x-3), so we know that the quadratic curve intersects the x-axis at x=2 and x=3. Since the coefficient of x^2 in the quadratic equation x^2-5x+6...
