Answer:
1) Option C is correct.
The Fahrenheit temperature varies with respect to the Celsius temperature with a rate of change of 9/5degrees F per degree C
2) The increase in Fahrenheit temperature if the Celsius temperature increases by 2 degrees = (18/5) degrees = 3.6°F
3) The decrease in Fahrenheit temperature if the Celsius temperature decreases by 24 degrees = 43.2°F
Step-by-step explanation:
1-degree change (increase or decrease) on the Celsius temperature scale is equivalent to a nine fifths 9/5 degree change on the Fahrenheit temperature scale
Let temperature in Celsius be C
And temperature in Fahrenheit be F
ΔC ∝ ΔF
ΔC = k ΔF
k = constant of proportionality
When ΔC = 1°, ΔF = (9/5)°
1 = k (9/5)
k = (5/9)
ΔC = k ΔF
ΔC = (5/9) ΔF
(ΔC/ΔF) = (5/9)
1) Which statement describes this situation?
The derivative or rate of change of C with respect to F for small changes in both quantities is approximately given as
(dC/dF) = (ΔC/ΔF)
And (ΔC/ΔF) = (5/9)
Hence,
(dC/dF) = (ΔC/ΔF) = (5/9)
Taking an inverse,
(dF/dC) = (ΔF/ΔC) = (9/5) °F/°C
So, It is evident that the right option is that the Fahrenheit temperature varies with respect to the Celsius temperature with a rate of change of 9/5degrees F per degree C
2) (dC/dF) = (ΔC/ΔF) = (5/9)
ΔC = 2°C
ΔF = ?
(ΔC/ΔF) = (5/9)
(2/ΔF) = (5/9)
ΔF = (2×9)/5 = (18/5) = 3.6°F
3) (dC/dF) = (ΔC/ΔF) = (5/9)
ΔC = -24°C
ΔF = ?
(ΔC/ΔF) = (5/9)
(-24/ΔF) = (5/9)
ΔF = (-24×9)/5 = (-216/5) = -43.2°F
Hope this Helps!!!
