Question

The temperature in a certain city ranges over the year from -10 degrees Celsius to 30 degrees Celsius. The functional relationship between the temperature in degrees Fahrenheit and the temperature in degrees Celsius is given by the equation F= C + 32, where F represents degrees Fahrenheit and C represents degrees Celsius. What is the range of the temperature in degrees Fahrenheit in this city? A --50 < F< 86 B. -14 < F< 62 C. 10 < F< 62 D. 14 < F< 86 OB DAI

Answer 1

To transform Celsius degrees into Fahrenheit degrees, we can use the next formula:

$F=C\cdot\frac{9}{5}+32$

Then, we have the first temperature in Celsius: -10. In Fahrenheit:

$F=-10\cdot\frac{9}{5}+32=14$

The second temperature in Celsius: 30. In Fahrenheit:

$F=30\cdot\frac{9}{5}_{}+32=86$

Therefore, the range of the temperatures in Fahrenheit is from 14 to 86 degrees.
