Chapter 2: Q47. (page 80)

For Exercises 46-48, use the information on temperatures at the left.
What temperature corresponds to $20 {}^{鈭�}C$ ?

Short Answer

Expert verified

The temperature that corresponds to $20 {}^{鈭�}C$ is $68 {}^{鈭�}F$ .

Step by step solution

– State the concept

The functional value at a point is obtained by putting the value in the expression of the function.

– List the given data

It is clear, from the given information, that the temperature of $0 {}^{鈭�}C$ is equivalent to the temperature of $32 {}^{鈭�}F$ and the temperature of $100 {}^{鈭�}C$ corresponds to the temperature of $212 {}^{鈭�}F$ .

– Compute the temperature

As obtained previously, the linear equation that corresponds the temperature in degree Celsius $x$ to the temperature in degree Fahrenheit $y$ is $y = \frac{9}{5} x + 32$ . Put $x = 20$ in $y = \frac{9}{5} x + 32$ to get

$\begin{array}{l} y = \frac{9}{5} (20) + 32 \\ = 9 (4) + 32 \\ = 36 + 32 \\ = 68 \end{array}$

This implies that the temperature that corresponds to $20 {}^{鈭�}C$ is $68 {}^{鈭�}F$ .
