the cost of airfare on Friday is $141

<u>Step-by-step explanation:</u>

Here we have , The average cost of airfare for a one-way ticket from Las Vegas to Los Angeles was $67 for the days of Monday through Friday. The cost of airfare Monday through Thursday was $40, $44, $50, $60 respectively. We need to find What was the cost of airfare on Friday.Let's find out:

Let amount of Friday be x , So Average cost of airfare for a one-way ticket from Las Vegas to Los Angeles  is given by :

⇒ \frac{40+44+50+60+x}{5} =67

⇒ \frac{194+x}{5} =67

⇒ 194+x =67(5)

⇒ x =335-194

⇒ x =141

Therefore , the cost of airfare on Friday is $141

A long distance phone service charges $0.30 for the first 10 minutes and $0.05 for each additional minute or fraction thereof. U
olga nikolaevna [1]

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

C=0.03+0.05\left \lceil t-10 \right \rceil

As we know that Greatest integer is discontinuous at every integer.

So, our Cost function is discontinuous at every integer after x>10.

The area of the square is 14*14 = 168 ft^2.

The area of the circle is πr^2. The radius is diameter/2 = 7. The area of the circle is 3.14*(7)^2 = 3.14*49 = 153.86 ft^2.

The area of the shaded part is the area of the square minus the area of the circle = 168 - 153.86 = 14.14 ft^2.
