Well the Digestive system breaks down your food and drinks and your Urinary takes out the harmful chemicals from the food and blood
break even means that the total income is equal to the total cost.
Therefore, we can equal the total gain to zero.
We have then:
![p (x) = x ^ 3 - 4x^2 + 5x - 20](https://tex.z-dn.net/?f=%20p%20%28x%29%20%3D%20x%20%5E%203%20-%204x%5E2%20%2B%205x%20-%2020%20)
Equaling zero we have:
![x ^ 3 - 4x^2 + 5x - 20 = 0](https://tex.z-dn.net/?f=%20x%20%5E%203%20-%204x%5E2%20%2B%205x%20-%2020%20%3D%200%20)
Rewriting the polynomial we have:
![(x-4) (x ^ 2 + 5) = 0](https://tex.z-dn.net/?f=%20%28x-4%29%20%28x%20%5E%202%20%2B%205%29%20%3D%200%20)
We observe that the polynomial only has a real solution.
Therefore we have:
![x-4 = 0x = 4](https://tex.z-dn.net/?f=%20x-4%20%3D%200x%20%3D%204%20)

Answer:
In quiet breathing inspiration involves muscular contractions and expiration is passive.
Explanation:
Respiration process involves two different stages, inspiration - inhalation- and expiration - exhalation-.
During inspiration, the diaphragm <u>contracts</u> and goes down, while intercostal muscles also <u>contract</u> and go up. These actions enhance the size of the thoracic box and <u>reduce internal pressure</u>. As a result, air flows in and fills the lungs.
During expiration, the <u>diaphragm relaxes</u> and the volume of the thoracic box diminishes, which causes the <u>pressure inside to increase</u>. In consequence, the lungs contract and the air is expulsed outside.

Answer:
Family members in the household need to receive the influenza vaccine."
Explanation:
Human Immunodeficiency virus (HIV) can cause acquired immunodeficiency syndrome AIDS, which is a viral disease which can destroy lymphocyte , thereby increasing susceptibility to infection and malignancy. A child with human immunodeficiency virus (HIV) infection will receive the same immunizations as other children, apart from live vaccines. All household members will also receive the influenza vaccine. Blood tests prior to immunizations are unnecessary and inaccurate.
