Two ocean beaches are being affected by erosion. the table shows the width, in feet, of each beach measured at high tide where 1995 is represented by year 0:

chart:

year number, western beach width (feet) , dunes beach width (feet),

0 100 20

5 90 45

10 80 70

11 78 75

12 76 80

15 70 95

part a:

describe the patterns shown by the erosion data measurements shown for each of the beaches in the table.

part b:

between which years will the beaches have approximately the same width?

part c:

assuming these rates remain constant, what can you do to get a better approximation of when the two beaches will have the same width?

instagram is better than go there instead lol

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
