Answer :
The formula for converting from degrees Fahrenheit, is an illustration of change of subject of formula, and the formula is: [tex]S =\sqrt{2A}[/tex]
Given that:
[tex]F(C) = 1.8C + 32[/tex]
Rewrite as:
[tex]F = 1.8C + 32[/tex]
Subtract 32 from both sides
[tex]F - 32 = 1.8C[/tex]
Divide both sides by 1.8
[tex]\frac{F - 32}{1.8} = C[/tex]
Rewrite as:
[tex]\frac{F - 32}{18/10} = C[/tex]
So, we have:
[tex]10 \times \frac{F - 32}{18} = C[/tex]
Simplify
[tex]5 \times \frac{F - 32}{9} = C[/tex]
[tex]\frac{5(F - 32)}{9} = C[/tex]
Rewrite the equation as:
[tex]C = \frac{5(F - 32)}{9}[/tex]
Hence, the formula that converts from degrees Fahrenheit is: [tex]C(F) = \frac{5(F - 32)}{9}[/tex]
