Question

PLEASE HELP, ive been stuck on this problem for and really 3 days now and need to get this done!

Answer 1

3. Two ocean beaches are being affected by erosion. The table shows the width, in feet, of each beach at high tide measured where 1995 is represented by year 0.
Year number Western Beach width (in feet) Dunes Beach width (in feet)
0 100 20
5 90 45
10 80 70
11 78 75
12 76 80
15 70 95
A. Describe the patterns shown by the erosion data measurements shown for each of the beaches in the table.

B. Between which years will the beaches have approximately the same width?

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?

Answer 2

well my best guess for A is to plot the data points.... that will allow you to decide how to describe the pattern...

so on a 1st quadrant number plane plot years on the horizontal axis and width on the vertical axis...

you will need to do this twice... 1 for Western and 1 for Dunes...

only then will you be able to answer B and C

Answer 3

How do i do that?

Answer 4

@campbell_st

Answer 5

well I'd get a piece of grid paper... and plot the points

just like this

Answer 6

im confused

Answer 7

for a, i have to explain in words...

Answer 8

@Campbell_st A has to be explained in words, not a graph.

Answer 9

The graph will help you see the patterns
THEN you may be able to describe in words

Plotting the chart is your best first step.

It require you to do a little work before oyu can answer...
