Normal systolic blood pressure is a function of age. For a woman, the normal systolic pressure, P, in millimeters of mercury (mm Hg) is modeled by P = 0.01 A2 + 0.05 A + 107

where A is age in years.

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

  40

Step-by-step explanation:

You want to find A for P=125. Putting the known values into the equation, we can solve for A.

  125 = 0.01A² +0.05A +107

  A² +5A -1800 = 0 . . . . . . . . . subtract 125; multiply by 100

  (A +45)(A -40) = 0 . . . . . . factor

The positive value of A that makes a factor zero is A=40.

The approximate age of the woman is 40.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
