So we just need to plug in our values and solve
![v = 20 \sqrt{273 + t}](https://tex.z-dn.net/?f=v%20%3D%2020%20%5Csqrt%7B273%20%2B%20t%7D%20)
we are given v is 369 so we have
![369 = 20 \sqrt{273 + x}](https://tex.z-dn.net/?f=369%20%3D%2020%20%5Csqrt%7B273%20%2B%20x%7D%20)
now we solve for x.
divide both sides by 20
square both sides
subtract 273 from both sides
![369 = 20 \sqrt{273 + x} \\ 18.45 = \sqrt{273 + x} \\ 340.40 = 273 + x \\ x = 67.4](https://tex.z-dn.net/?f=369%20%3D%2020%20%5Csqrt%7B273%20%2B%20x%7D%20%20%5C%5C%2018.45%20%3D%20%20%5Csqrt%7B273%20%2B%20x%7D%20%20%5C%5C%20340.40%20%3D%20273%20%2B%20x%20%5C%5C%20x%20%3D%2067.4)
so a temp of about 67 degrees C
Answer: mean is 66 and the median height is 68.
Step-by-step explanation: uh I dont know what to put here....?
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.
