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? – 0.03y + 121 %3D | 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 45 years. 133.820 B.) If a person's systolic pressure is 131 mm Hg, what is their age (rounded to the nearest whole year)?

Ratios

A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.

Trigonometric Ratios

Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
