Adoctor orders 250 mg of rocephin to be taken by a 19.8 ib infant every 8 hours. the medication label shows that 75-150 mg/kg per day is the appropriate dosage range. is this doctor's order within the desired range?

Yes, doctor's order is within the desired range.

Step-by-step explanation:

We need to first convert 19.8 lb to kg.

We know that 1 kg=2.20 lb

Therefore, the weight of infant=

Minimum Desired Dosage)

Maximum Desired Dosage  

Since there are 24 hours in one day and the medication is ordered every 8 hours.

3 times per day doctor ordered medication .

Total amount of Rocephin in a day750 mg ordered per day

And 750 mg is within the desired range of 675-1,350 mg

So, yes doctor has ordered a dosage within the desired range.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
