The function 't' which maps temperature ...

The function 't' which maps temperature in degree Celsius into temperature in degree Fahrenheit is defined by `t (C ) = (9C)/5 +32`. Find t (0)

Text Solution

Verified by Experts

i) `t(0)=9 xx 0/5+32=32`
ii) `t(28)=9 xx 28/5+32=252+160/5=412/5`
iii) `t(-10)=9 xx-10/5 .+32=-90+160/5=70/5=.14`
iv) `t(C)=212 rarr 9 C/5+32=212 rarr 9 C/5=212-32=.180 rarr C=180 xx 5/9=100`
