A formula for the relationship between weight and blood pressure in children is given by the formula below where P(x) is measure
photoshop1234 [79]

Answer:

The rate of change of blood pressure at the 50-pound weight level is 0.26

The rate of change of blood pressure at the 80-pound weight level is 0.16

Step-by-step explanation:

We have, P(x) = 12.9(9 + ln x)

We need to compute the rate of change of blood pressure P(x) so, we will differentiate the function P(x) with respect to x.

P(x) = 12.9(9 + ln x)

P(x) = 116.1 + 12.9ln x

Differentiating with repect to x:

\frac{d(P(x))}{dx} = 0 + 12.9 (\frac{1}{x})

\frac{d(P(x))}{dx} = 12.9 (\frac{1}{x})

The differential of ln x is \frac{1}{x} and the differential of constant terms is 0.

The rate of change of blood pressure at the 50-pound weight level can be calculate by substituting 50 in place of x, so

\frac{d(P(x))}{dx} = 12.9 (\frac{1}{x})

          = 12.9 * (1/50)

          = 0.258

\frac{d(P(x))}{dx} = 0.26

Similarly, The rate of change of blood pressure at the 80-pound weight level can be calculate by substituting 80 in place of x, so

\frac{d(P(x))}{dx} = 12.9 (\frac{1}{x})

          = 12.9 * (1/80)

          = 0.16125

\frac{d(P(x))}{dx} = 0.16
