Which point in this graph shows the beginning of a period of exponential growth? a. point d b. point c. point a d. point b

Point A

Explanation:

The s shape curve beginning represents the point A. The point A  in the graph shows the beginning of a period of exponential  growth.

The Point B is near to point A whereas point c is after point B. The point D represents the carrying capacity. The carrying capacity is the maximum size of population that can be sustained by  environment. Thus, the point A is representing exponential growth beginning.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
