Answer:
(a) The temperature at a specific location as a function of time.
This is a continuous function as the temperature cannot increase in an instant like time.
(b) The temperature at a specific time as a function of the distance due west from New York City.
This is a continuous function as the temperature in one location is affected by its neighboring places.
(c) The altitude above sea level as a function of the distance due west from New York City.
The altitude above sea level can be discontinuous at a cliff, or continuous at very deep hole.
(d) The cost of a taxi ride as a function of the distance traveled.
This is a discontinuous function as the cost still raises if you make a stop.
(e) The current in the circuit for the lights in a room as a function of time.
This is a discontinuous function as the function takes the value of 0 when the switch is off and 1 when the switch is on.
The electron traveling speed makes this discontinuous.
Answer:
16
Step-by-step explanation:
Total cost = deposit + (hourly pay x number of hours)
let number of hours be h
68 = 20 + (3 × h)
3h = 68 - 20
3h = 48
h = 48/3
h = 16
Therefore the boat was rented for 16 hours
Answer:
They are the same line
Step-by-step explanation:
When you have equations of line and want to compare them, make sure the y is isolated (by itself)
the second equation -2y = 4x-8 is not isolated
To isolate, divide both sides by -2
Now you have y=-2x+4, which is the same equation as the first!
(remember that if you divide a negative number by a negative number, you will get a positive one)
Answer:
C
Step-by-step explanation:
y = x+4

Answer: 56.816
Step by step: 10+20+23=53
7.2% of 53= 3.816
53+3.816=56.816
