Round the answer to the nearest

By knowing the <em>blood</em> pressure and applying the <em>quadratic</em> formula, the age of a man whose normal <em>blood</em> 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 <em>quadratic</em> function that models the <em>blood</em> 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 <em>blood</em> pressure and applying the <em>quadratic</em> formula, the age of a man whose normal <em>blood</em> pressure is 129 mm Hg is 40 years old.

Sarah is building a set of four shelves each shelf will have two supports in the shape of right isosceles triangle's each shelf
Rama09 [41]

Answer:

784 in² of wood

Step-by-step explanation:

Sarah  needs two supports by shelf, and  she will build 4 shelves

then she will need 8 supports

Now each support is a  right isosceles triangle.

Area of a triangle is

A(t)  = 1/2 *b*h      where  b is the base and h is the heigh of the triangle.

A right isosceles triangle has two sides ( base and heigh equals) and in our particular case are equals to 14 in, therefore

A(t)  = 1/2*14*14

A(t)  =  98 in²

Sarah needs 8 pieces of 98 in² she needs

A =  8*98

A  = 784 in² of wood
