If the wind is blowing from the east at 87 km/h and an airplane is on a heading of 225° with an airspeed of 750 km/h, find the ground velocity of the airplane
and the direction of flight.
(I’ve found the magnitude for the ground velocity, just got stuck finding the angle)

Solve -.016x= -16. need solving this

For [tex]f(x) = 4x + 1[/tex] and (x) = [tex]g(x)= x^{2} -5,[/tex] find [tex](\frac{g}{f}) (x)[/tex]a. [tex]\frac{x^{2} - 5 }{4x +1 },x[/tex] ≠ [tex]-\frac{1}{4}[/tex]b. x[tex]\frac{4 x +1 }{x^{2} - 5}, x[/tex] ≠ ± [tex]\sqrt[]{5}[/tex]c. [tex]\frac{4x +1}{x^{2} -5}[/tex]d.[tex]\frac{x^{2} -5 }{4x + 1}[/tex]

What are the measures of angles a, b, and c? show your work and explain your answers. 25 points
