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 0.006y ^ 2-0.01y + 121 gives a person's blood pressure, P, at age and years.A.) Find a systolic pressure, to the nearest tenth of a millimeter, for a person of age 47 years B.) If a person's systolic pressure is 134.34 mm Hg, what is their age (rounded to the nearest whole year)?
