Ying is a professional deep water free diver. his altitude (in meters relative to a sea level) x seconds after diving is modeled by d(x)=1/36(x-60)^2-100 what is the lowest altitude ying will reach

100 feet below sea level

Step-by-step explanation:

Our function is

This is written in vertex form,

f(x) = a(x-h)²+k,

where (h, k) is the vertex of the function.

The vertex of a function is either the maximum or the minimum value of a quadratic function.

For our function, the value in place of h is 60 and the value in place of k is -100; this makes the vertex

(60, -100).

This means at 60 seconds, the diver will reach a minimum of -100 feet, or 100 feet below sea level.

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
