What is the approximate age of a woman whose normal systolic pressure measures 125 mm Hg?

sashaice [31]

The approximate age of a woman whose normal systolic pressure measures 125 mm Hg is 31

The function is given as:

$P(A) = 0.006A^2 - 0.02A + 120$

When the normal systolic pressure is 125, it means that:

$P(A) = 125$

So, we have:

$125 = 0.006A^2 - 0.02A + 120$

Subtract 125 from both sides of the equation

$0= 0.006A^2 - 0.02A + 120 -125$

$0= 0.006A^2 - 0.02A - 5$

Rewrite the equation as:

$0.006A^2 - 0.02A - 5 = 0$

Using a graphing calculator, we have:

$A = \{30.58, -27.25\}$

But age cannot be negative.

So, we have:

$A = 30.58$

Approximate

$A =31$

Hence, the age of the woman is 31
