Question

CAN SOMEONE PLZ HELP?!?!?!?(MEADL+FAN)






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

Answer 1

@Nasa7 CAN U HELP

Answer 2

So, The western Beach is losing sand, dunes beach is gaining sand. In a span of about 11 to 12 years

Answer 3

oh i was over thinking it
thanks a ton ur a life saver ive been on this question 4 hrs

Answer 4

is that all i have to put

Answer 5

No I am still typing :P

Answer 6

I am beginning to explain it.

Answer 7

ok

Answer 8

So, the western beach looses 2 ft while dunes beach get 5ft more per year.

Answer 9

So, we would get a constant slope when you plot the graphs
so 2 less per year for western and 5 more per year for dunes so both would be linear

Answer 10

ok i get it thanks for explaining ,i dont think i have to graph it just write it out

Answer 11

Anything else?

Answer 12

can u check my work for
Between which years will the beaches have approximately the same width?
11 and 12/2006-2007

Assuming these rates remain constant, what can you do to get a better approximation of when the two beaches will have the same width
-2x + 100 = 5x + 20
100 - 20 = 7x
80 = 7x
80/7 = x
x ~11.43 years

Answer 13

So what I am going to have you do is there are many posts just like this read through this post then tell me if you have any other questions :)
