1. ### A pilot of a downed airplane fires the emergency flare into the sky. The path of the flare is modeled by the e?

so make a stickman drawing. y = h and x = d (9x + 14)/10 = 60 - 0.096(x-25)^2 9x + 14 = 600 - 0.96(x-25)^2 -0.96x^2 -x(9 + ( 50*0.96)) + 586 = 0 use the binomial solution x = -b +- (b^2 - 4ac) / 2a where ax^2 + bx + c = 0; to find the two x's where line of site meets flare. -55 +- (27.83451) = -82.834510953131545903632868035956 & 27...

2. ### help with a related rates problem involving an airplane?

Let the plane's distance from the point above the radar station = a Let the plane's distance from the radar station = b I don't know how to derive the cosine formula, assuming that's part of the question, but using it in this problem, we get: b^2 = a^2 + 25 - 2(a)(5)cos(90° + 35°) = a^2 + 25 - 10 a cos 125...

3. ### How fast are the airplanes separating at 2 p. m.? Round the answer to the nearest integer.?

At 2pm, the eastbound plane has traveled 240km, while the southbound plane has flown 180km. The separation at this point is sqrt(240^2 + 180^2) = 300km. As to how fast they are separating, keep in mind that one plane left an hour later than...

4. ### An airplane makes a 990 km flight with a tailwind and returns, flying into the same wind.?

Let wind speed = x km/h Distance = 990 km ______________Downwind_______Upwind Speed (km/h)____600 + x_________600 - x 990 / ( x + 600 ) + 990 / ( 600 - x ) = 10/3 2970 (600 - x) + 2970 (x + 600) = 10 (600 + x) (600 - x) 1782000 + 1782000 = 10 ( 360000 - x ² ) 10 x ² = 3,600,000 - 3...

If it were travelling east or west 0 degrees, it has just been sped up or slowed down. If it were travelling north or south then you can draw a triangle showing the planes path... Draw a line going up for...

6. ### My friend followed his RC airplane for 10 minutes before it went down 310 miles away How fast was it going?

310 miles in 10 minutes is 31 miles per minute or 1860 miles per hour. Your friend's model was flying at about 2.5 times the speed of sound! That's some model!

7. ### A airplane is traveling at a cruise speed of 185 Miles Per Hour. How long would it take to travel a distance of 28 miles?

Remember the basic distance formula: D = RT Solve it for time: T = D/R Plug in your values: D : distance in miles (28) R : rate in miles per hour (185) T : time in hours T = 28/185...

9. ### An airplane shown below is in level flight at an altitude of 500m and with a speed of 150km/h.?

Okay, well, there is no image or anything, so I can't give you a perfect answer, because I can't know exactly what it is that I'm calculating against. However, if the plane dropped its bomb right now, the bomb would travel 420.0...
