V^2 = Vo^2 + 2ad a=(V^2-Vo^2)/2d=(900-0)/7400=0.122 m/s^2 d2 = 30m/s * 410s = 12300 m. d3 = (V^2-Vo^2)/2a d3 = (0-900)/-0.130 = 6923 m.

Shorted.
Math
1. The diagonal divides the rhombus into 2 congruent triangles. The altitude bisects the diagonal. (16/2)^2 + Y^2 = 10^2 Y^2 = 100-64 = 36 Y = 6 = Altitude. Area = 2(16/2 * 6) = 96 in^2.
Math
2. Decagon: 10 sides. Area = 2.94*r^2 = 2.94*4^2 = 47 cm^2.

d = 2.5m/s * 6min*60s/min = 900 m. Work = F*d = 145cos30 * 900 = 443,856 J. = 444 kJ.
Algebra
x^2/12 + 11x/9 = 300 Multiply both sides by 36: 3x^2 + 44x = 10800 3x^2 + 44x - 10800 = 0 Use Quadratic Formula: X = 53.1 mi/h.
