A community that has progressed so much that it is stable and balanced is called a(n) _______ community.
Rzqust [24]

Answer:

c. Climax

Step-by-step explanation:

Climax community is an ecological community in it final stage of succession,  in which the species that makes up the community are relatively stable unless   a rare earth disaster like earthquakes, fire etc  destabilize the system.

The climax community has reached the stable stage. The community is well defined and extensive . This stability is usually actualized when more complex organisms replace more simple organism. Succession in this kind of community has occurred severally until it reaches it reaches the climax stage. Most climax community takes hundreds and millions of years to reach stability. This stability is achieved through succession : a process whereby natural communities is replaced by another. For example grass may invade an ordinary flat sandy surface then the grass will provide humus for other more complex species to grow like oaks and beeches tree before it reaches a stable community.

amm1812
This is the derivitive of x
critical points are where the first derivitive is equal to 0 or where the derivitive doesn't exist

ok, it is 0 at x=0 and 2
so I is true but not II

the point of inflection is where the slope of the 1st derivitive=0
that is at x=1
so III is true


I and III

Find the LCM of the polynomials. 2x - 4, 5x - 10
Marizza181 [45]

Answer:

10x - 20

Step-by-step explanation:

First, factor both polynomials.

2x - 4 = 2(x - 2)

5x - 10 = 5(x - 2)

The LCM is the product of the common and not common factors with larger exponent.

LCM = 2 * 5 * (x - 2)

LCM = 10(x - 2) = 10x - 20

If you deposit $6000 into an account paying 6.5% annual interest compounded quarterly, how long until there is $12600 in the acc
grandymaker [24]
Use this formula:

K = K_0 * (1+r)^n

Insert and solve for n: 

12600 = 6000 * (1+0.065)^n

n = 11.78

So about 12 quarters. 

Hope that helped.
