Answer: sin(34) = 0.52908268612
substitute for your equation;
h(x) = f(x) - g(x)
h(x) = (3x + 2) - (-2x -4)
h(x) = 3x + 2 + 2x + 4 (minus and minus = addition)
h(x) = 3x + 2x + 2 + 4 (combine like terms)
h(x) = 5x + 6
Hope that helps! :D
Using equation of motion.
S = ut + (1/2)gt²
Where S = Height, t = time, g = acceleration due to gravity = 9.8 m/s²
time, t = 8 seconds
Since it was dropped from height, initial velocity, u = 0
S = 0*t + (1/2)gt²
S = (1/2)gt²
S = (1/2)*9.8*8² = 4.9 * 8 * 8 = 313.6
Therefore the ledge is 313.6 m tall.
