In order for the growth rate to remain constant what must happen to the birth rate?

1 answer:

5 0

In order for the growth rate to remain constant, the birth rate must equal the death rate. This is the number of the population being born and the number of people dying. A birth replaces a death and vice versa, so if the birth rate and the death rate are the same, there are the same number of organisms total.

Water, organic biological molecules, sodium chloride, glucose.

A compound is anything composed of two or more separate elements.

O2 and H2 are a singular elements, and a chain of carbon atoms is multiple of the same element, so these are not considered compounds.

Sodium chloride is sodium and chlorine, and water is oxygen and hydrogen. Glucose is a compound of sugar, and organic biological (or biomolecules) are made up of carbon and hydrogen, so these are all considered compounds

If I subtract 20 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from t

Natasha_Volkova [10]

The value of the unknown number is 10.5.

Let the unknown number = x

When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:

(x - 20)² = x² - 20

expand the equation;

x² - 40x + 400 = x² - 20

collect similar terms together;

x² - x² - 40x = -20 - 400

-40x = -420

$x = \frac{420}{40}\\\\ x = 10.5$

Thus, the value of the unknown number is 10.5.
