What term is used to describe the graphical representation of the change in microbial population over time?
ruslelena [56]

Answer:

The term exponential is often used.

Step-by-step explanation:

The term exponential is used to represent changes in population over time.  The idea of (positive) exponential is that the higher the number, the higher the growth. You can relate this with a population, because the higher the population, the more opportunities for it to multiply, thus, the higher it grows.

Usually the way to meassure the population of an species after certain number of years x, you use an exponential function of the form

f(x) = K_0 * a^x

For certain constants K₀ and a. K₀ is the initial population at the start of the experiment and <em>a </em>number of exponential growth. Essentially, the population of the species is multiplied by a during each year.

For example, if K₀ = 1000 and a = 2, then the population at the start of the experiment is 1000. After the first year is 1000*2 = 2000 and after the second year it is 2000*2 = 4000. Note that, not only the population grow during the years, but also the amount that the population increases also grow: in the first year it grows 1000, and between the first and second year it grows 2000.

Each marble bag sold by Lucy's Marble Company contains 7 yellow marbles for every 5 green marbles. If a bag has 45 green marbles
Elan Coil [88]

Answer:

63 yellow marbles

Step-by-step explanation:

You can set up this equation as a proportion:

7/5 = x/45

Divide 45 by 5 to see what 7/5 must be multiplied by to get to x/45.

You should get 9, so also multiply 7 by 9 to get this:

7/5 = 63/45

This shows that there are 63 yellow marbles for 45 green marbles.

Please thank, rate, and mark brainliest! :)
