Question

A person's systolic blood pressure, which is measured in millimeters of mercury (mm Hg), depends on a person's age, in years. The equation:

P=0.007y^2−0.01y+119

gives a person's blood pressure, P, at age y years.

A.) Find the systolic pressure, to the nearest tenth of a millimeter, for a person of age 50 years.

B.) If a person's systolic pressure is 130.36 mm Hg, what is their age (rounded to the nearest whole year)?

Answer 1

P = 0.007(50²) − 0.01(50) + 119

130.36 = 0.007y² − 0.01y + 119
