Is this question multiple choice, and if yes what are the options?

I graphed f(x) = 7x 

Maybe this will help you find your answer, but without the following options I can't tell you which one is true.

To determine drug dosages, doctors estimate a person’s body surface area (BSA) (in meters squared) using the formula BSA = √ h m
krok68 [10]

Answer:

Step-by-step explanation:

Given that a person’s body surface area (BSA) (in meters squared) using the formula

BSA =\frac{\sqrt{hm} }{60}

We are to calculate the rate of change of BSA with respect to mass for a person of constant height h = 180 from m =70 to m =80

For this we calculate BSA for 80 kg and BSA for 70 kg first

Rate of change = BSA(80)-BSA(70)

=\frac{\sqrt{180*80} }{60} -\frac{\sqrt{180*70} }{60} \\=2-1.871\\=0.129

i.e. rate of change per 10 kg is 0.129

No BSA does not increase more rapidly
