That means the standing person still has 40 percent of total capacity in the lungs, undergoing gas exchange after quietly exhaling. a person in supine position has only 20 percent of that capacity in reserve after exhaling passively. which person will have to breathe sooner to meet the needs for life?

Supine

Step-by-step explanation:

Based on the information provided within the question it can be said that the person in the Supine position will have to breathe sooner in order to continue living. This is based on the fact that the person in the supine position has exactly half the percentage of lung capacity as the person standing. Therefore the person standing can last double what the person in the supine position can.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

squares, rhombus, rectangles
