The equation for the cross section of a parabolic satellite television dish is y=1/50x^2 measured in inches, how far is the focus from the vertex of the cross section?

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
