For this case, the first thing we must do is define variables.
We have then:
t: number of hours
F (t): total charge
We write the function that models the problem:
Where,
b: represents an initial fee.
We must find the value of b.
For this, we use the following data:
Her total fee for a 4-hour job, for instance, is $ 32.
We have then:
From here, we clear the value of b:
Then, the function that models the problem is:
Answer:
the function's formula is:
Answer:
Step-by-step explanation:
Let the coordinate of the points W, V and R are and
respectively.
The coordinate of the section point, which divides the line joining the two points
and
in the ration
is
and
.
The given ration is,
.
The exact point can be determined by putting the value of the exact coordinate in the above-obtained formula.
