Answer correctly for brainliest and also get a ! don't answer if you don't know it !

you would need to use the distance formula for this square root of (x2-x1)^2+(y2-y1)^2 

sqrt of (7-5)^2+(10-1)^2

sqrt of 2^2 + 9^2

sqrt of 4+81

sqrt of 85

9.2

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

next, the dose

72.7kg * 100mg/kg = 7270mg
