A mining operation was digging a mine shaft into the earth. On Monday the shaft was 44 meters below the surface, -44. Here are the depths of the mine shaft, but they are out of order. -44, -152, -92, -68, -140, -116, -56, -104, -128
A. Arrange them in the correct sequence and write them in the table below.
B. What was the common difference?
C. What does this common difference tell you about the mining operation?
Given that a mining operation was a digging a mine shaft into the earth. On Monday the shaft was 44 meters below the earth surface . But here are the depths of the mining shaft :-44, -152, -92, -68, -140, -116, -56, -104, -128 .
We need to:
i) Arrange them in correct sequence and fill the given table.
ii) What is the common difference,
iii) What does the common difference tell about the mining operation.
On Monday the shaft was -44 feet below the surface. So each day it must go still below the earth.
So arrange them in descending order.
So the correct sequence is -44,-56,-68,-92,-104,-116,-128,-140,-152.
So now let us tabulate the readings:
|
Day |
Meters below the earth surface. |
|
Monday |
-44 |
|
Tuesday |
-56 |
|
Wednesday |
-68 |
|
Thursday |
-92 |
|
Friday |
-104 |
|
Monday |
-116 |
|
Tuesday |
-128 |
|
Wednesday |
-140 |
|
Thursday |
-152 |
|
Friday |
-166 |
