HOW DOES THE RESPIRATORY SYSTEM WORKS? There are specific parts of the body used for beathing. When you are breathing you are inhaling oxygen and exhaling caron dioxide. The body system that helps you inhale and exhale is called Resplratory system. Glve 5 parts of Respiratory System.

6. 1. If \( y=\frac{1}{3} x^{3}+\frac{1}{2} \quad x^{2}-6 x+8 \) \( \begin{array}{ll}\text { Find } & \text { a) the critical points } \\ \text { b) the maximum and minimum } \\ \text { values of } y \text { by First Derivative Test }\end{array} \)

Graph the linear equation. \( y=-2 \frac{3}{4} \)

2. Dada id eadacion general \[ \begin{array}{ll}x^{2}+y^{2}+5 x+4 y+5=0 & h=\frac{-D}{2 A}\end{array} \]

What volume of \( 6 \mathrm{~mol} / \mathrm{L} \mathrm{HCl} \) is required in the preparation of 100 mL of \( 1 \mathrm{~mol} / \mathrm{L} \mathrm{HCl} \) ?

Graph the linear equation by finding and plotting its intercepts. \[ -5=2 x+y \]
