1. ### SAT MATH PROBLEM. How do I solve this?

You have the question and you have given the correct answer. So what is it you need help with? It may seem counterintuitive, but if you have the same unit (1 cm) equal *half* the real measurement, that means the model will have to be *twice* as big to represent the same real life object. Let's...

2. ### A pedestrian walks east at a rate of 6 km/hr. The wind pushes him northwest at a rate of 13 km/hr. Find the direction and magnitude?

...walk in the first place. However, if we imagine that this is an airplane, not a pedestrian: c^2 = a^2 + b^2 - 2ab*cos(C) c^2 = 6^2 + 13^2 - 2*6*13...

6. ### An airplane moving with a velocity equal to 300 mph when the velocity was increased with uniform acceleration to 600 mph in 5 minutes.?

300 mph = 300/60 miles per minute = 5 miles per minute 600 mph = 600/60 miles per minute = 10 miles per minute v(5) = 10 v(0) = 5 (10 - 5) / (5 - 0) = 5/5 = 1 v(t) = t + 5 Integrate s(t) = (1/2) * t^2 + 5t + C s(5) - s(0) => (1/2) * 5^2 + 5 * 5 - (1/2) * 0^2 - 5 * 0 => (1/2) * 25 + 25 =>...

Presumably "from a direction of 53.0 degrees" means the wind is blowing approximately towards the SW or WSW. So add the airspeed, -192 j, to the wind speed, which is 13.0 (i cos(233) + j sin(233)) = -7.8236 i - 10.3823 j. The resultant speed...
