According to the statement, we have the following information:
(1)
(2)
(3)
(4)
From (2), we have the following expression:
(5)
If we know that and
, then the coordinate of
is:
The coordinate of is 13.36.
Answer:
Step-by-step explanation:
Given:
The level of a lake is falling linearly.
On Jan 1, the level is 452 inches
On Jan 21, the level is 378 inches.
Now, a linear function can be represented in the form:
Where, 'm' is the rate of change and 'b' is initial level
So, let Jan 1 corresponds to the initial level and thus b = 452 in
Now, the rate of change is given as the ratio of the change in level of lake to the number of days passed.
So, from Jan 1 to Jan 21, the days passed is 21.
Change in level = Level on Jan 21 - Level on Jan 1
Change in level = 378 in - 452 in = -74 in
Now, rate of change is given as:
Hence, the function to represent the lake level is
Where, 'x' is the number of days passed since Jan 1.
