If f (x) = x2 + 5x – 14, find f (–2).

-28

Step-by-step explanation:

f(-2)= (-2)(2) + 5(-2) - 14

f(-2)= -4 + (-10) - 14

f(-2)= -28

Step-by-step explanation:

f(x) = x² + 5x - 14

f(-2) = (-2)² + 5(-2) - 14 = 4 - 10 - 14 = -20

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

translate k to n and reflect across the line containing jk.
