Is this just asking for the Fahrenheit formula in terms of C?
I'm sorry, I really don't know
I'm not 100% sure, but that what it seems to me. Wait for someone to confirm. Do you know How to solve for F in term of C?
I believe he wants us to use variables like independent, dependent etc. I just don't understand that
and no to your answer
Do you not understand dependent an independent all together or just for this specific example
You are right, the question asks for you to assign letters to the variables :-)
Let F = the Fahrenheit measure of temperature Let C = the Celsius measure of temperature
If we graph distance as function of time, this means that on the x axis we would put time and on the y axis we would put distance. So let's say after 1 hour we drove 60 miles, at point x = 1, y = 60 at point x = 2 y = 120. X which is time is independent. The distance traveled is dependent on time. Does this make sense?
Another way of putting it; time is not dependent on distance, rather distance is dependent on time.
yes that makes sense
Can you translate the the words in the sentence into an equation?
So the x axis is independent and y axis is dependent. Another way of thinking about it is x = is input y = output. If you can graph out the following on paper it would be helpful...
F = 32 + (9/5)*C
Do you know the freezing and boiling points of water in F and C? I'm trying to help you understand why the formula that was just posted is true.
skullpatrol I do get that or it could be1.8 instead of 9/5 right?
To use function notation: F = g(C) = (9/5)*C + 32
Yes, 9/5 = 1.8
Answer: g(C) = 1.8*C + 32
THANK YOU SO MUCH!!! i GET IT!!
Note: F = g(C) is a symbolic way of saying the temperature as measured in Fahrenheit is a function, g of the temperature measured in Celsius.
LEIBY i BELIEVE IT IS 0 C and 32F for freezing and 212F and 100C for boiling
Correct. If you want do understand why F = 32 + (9/5)*C. Let me know and I'll show you.
Please show me
Since water freezes at 0 degrees C and boils at 100 degrees C. Draw on the x axis a line from 0 to 100. (It doesn't need to be exact, you can make markings at increments of 10 if you'd like.)
Make the Y axis go up till 220. Mark on the Y axis where the freezing point and boiling points are (32 and 212). Make a line between the 2 points. Since y = slope x + intercept, calculate the slope which is (y2 - y1) / (x2 - x1) which is (212 - 32)/ 100 - 0) which is 180 / 100 simplified = 9/5 so the slpe is 9/5. The intercept is 32. So, Y = (9/5)x + 32. Or F = (9/5)C + 32
wow!! you are brilliant! Math is not my subject but I keep trying, now that I found open study I may get pretty good at it with people like you and skull. Thank you sooooo much for your patience and understanding. Now I am going to write down what you said and go to bed!!! I am sooo tired.
I'm not brilliant, I also keep trying, till I get it.
you have a nice rest of the night! Well, it is after 1 am now! Gotta get up at 6:30. What state do you live in?
One more thing, so which would be the independent and the dependent variable?
x is independent y is dependent So in F = 32 + (9/5)*C F is dependent on C
got it!! Thank you again!
