A lake currently has a depth of 30 meters. As sediment builds up in the lake, its depth decreases by 2% per year. This situation represents
The rate of growth or decay, r, is equal to
So the depth of the lake each year is
times the depth in the previous year.
It will take between
years for the depth of the lake to reach 26.7 meters.

answer:

what is your question that you ask

step-by-step explanation:

c(x)= 6x + 3

step-by-step explanation:

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
