Answer:
Slope = -2
Step-by-step explanation:
Since, slope =
Rise = -(y-intercept)
Run = (x-intercept)
From the graph attached,
y - intercept = -(4) = -4
x - intercept = 2
Therefore, slope the line given in the graph attached will be,
Slope = = -2
Slope = -2
Given :
A water well rig has dug to a height , H = 60 feet after one full day of continuous use .
To Find :
If the height is currently 143.6 feet how time it been running .
Solution :
It is given that height after 24 hours of use is 60 feet .
So , height loose in 1 hours is :
Now , time taken to cover a height of 143.6 feet is :
Therefore , time taken is 57.44 hours .
Hence , this is the required solution .
