Answer: Our Cost function is discontinuous at every integer after x>10.
Step-by-step explanation:
Since we have given that
For the first 10 minutes , the service charges = $0.30
Let the number of additional minute be 't'.
Amount charge for each additional minute = $0.05
Using the greatest integer function:
So, Cost C of a call in terms of time 't' minutes would be
As we know that Greatest integer is discontinuous at every integer.
So, our Cost function is discontinuous at every integer after x>10.
Answer:
- ( -9, 5)
Step-by-step explanation:
We can observe that x coordinate increases on line segment JL from J and y coordinate decreases.
<u>The difference in x:</u>
- -18 - 3 = -21
<u>The difference in y:</u>
- 17 - (-11) = 28
<u>Point K is at 3/7 distance from J, so it's coordinates will be:</u>
- -18 -(-21*3/7) = -18 + 9 = -9
- 17 - (28*3/7) = 12- 7 = 5
So K = ( -9, 5)
