To determine drug dosages, doctors estimate a person’s body surface area (bsa) (in meters squared) using the formula bsa = √ h m / 60 , where h is the height in centimeters and m the mass in kilograms. calculate the rate of change of bsa with respect to mass for a person of constant height h = 180 . what is this rate at m = 70 and m = 80 ? express your result in the correct units. does bsa increase more rapidly with respect to mass at lower or higher body mass?

Step-by-step explanation:

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

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 =

=

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

No BSA does not increase more rapidly

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
