10^2 = 10 × 10
10^3 = 10 × 10 × 10 = 1000
10^4 = 10 × 10 × 10 × 10
Neither, for lines to be parallel they have to have the same slope, and for lines to be perpendicular they have to be the negative reciprocal of the slope of the other line. In this case, the line perpendicular to the line with slope m=10 would be m=1/-10 or -1/10
Step-by-step explanation:
change the unit
50 km per 1 hour
50 km/h = 50,000 m/ 3600 s = 13.8 m/s
the lorry speed is 13.5 m/s or 0.3 m slower than the limit
