Question

The function 't' which maps temperature in degree Celsius into temperature in degree Fahrenheit is defined by $t(C) = \frac{9c}{5} + 32.$ t(-10)

Answer 1

t(c) = 9c/5 + 32

When c = -10

f(-10) = 9(-10)/5 + 32

f(-10) = -90/5 + 32

f(-10) = -18 + 32

f(-10) = 14

Answer 14 Fahrenheit Height

Answer 2

HEY DEAR ... ✌️

=) Here's , Your Answer :-

=) Given ,
=) t (c) = 9c/5 + 32

=) When we take , c = -10

=) f (-10) = 9(-10)/5 + 32

=) f (-10) = -90/5 + 32

=) f (-10) = -18 + 32

=) f (-10) = 14. (ans.)

Extra information :-

=) Celcius is an international unit for determining temperature if the body is cold it will decrease it's numerical value . But , if it's hot the numerical value will be increased .
We can also convert Celcius to Fahrenheit . But , celcius is much used nowadays due to its easily calculated system .
