By knowing the blood pressure and applying the quadratic formula, the age of a man whose normal blood pressure is 129 mm Hg is 40 years old.

<h3>How to use quadratic equations to determine the age of a man in terms of blood pressure</h3>

In this problem we have a quadratic function that models the blood pressure as a function of age. As the latter is known, we must use the quadratic formula to determine the former:

129 = 0.006 · A² - 0.02 ·A + 120

0.006 · A² - 0.02 · A - 9 = 0

$A = \frac{0.02 \pm \sqrt{0.006^{2}-4\cdot (0.006)\cdot (- 9)}}{2\cdot (0.006)}$

A = 1.667 + 38.733

A = 40

By knowing the blood pressure and applying the quadratic formula, the age of a man whose normal blood pressure is 129 mm Hg is 40 years old.

Which number gives the exact value of four and five sixths?

Sonbull [250]

Answer: Choice A

four and eighty three hundredths with the three repeating

In other words, 4.8333...

====================================================

Explanation:

Use long division to find that 5/6 = 0.8333... where the 3s go on forever. The steps for the long division are shown in the diagram below. You can use a calculator to confirm.

Therefore, 4 & 5/6 = 4 + 5/6 = 4 + 0.8333... = 4.8333...

Since the 3 repeats forever, we can use a horizontal bar to place over the 3 like this $4.8\overline{3}$
