Graph the following piecewise function on a separate sheet of graph paper and an upload graph x + 4. -4 <_ x<3
2x-1. 3<x<6
​

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

sorry, i can't understand your question. will later if you describe more clearly!

: )

1. minimum

2. 6400

3. eight

hope this !
