Math question C= 5
9
(F−32)
The equation above shows how temperature F, measured in degrees Fahrenheit, relates to a temperature C, measured in degrees Celsius. Based on the equation, which of the following must be true?
A temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of
5
9
degree Celsius.
A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit.
A temperature increase of
5
9
degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.
A) I only
B) II only
C) III only

D) I and II only

Explanation:

The equation which related Fahrenheit to Celsius is given as:

For F = 32, C = 0

For F = 33, C = 5/9

For F = 34, C = (2)(5/9)

Hence, Statement (I) is correct

For C = 0, F = 32

For C = 1

As F₂ - F₁ = 33.8 - 32 = 1.8 , Statement (II) is correct

As it contradicts with Statement (I), and Statement (I) was found correct, Statement (III) is incorrect

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
