Answer: (i) 32

(ii) \frac{415}{2}

(iii) 14

(iv) 100

Step-by-step explanation: दिया है : t(C) = \frac{9C}{5} + 32

(i) t(0) = \frac{9}{5} × 0 +32

= 0 + 32

= 32

(ii) t(28) = \frac{9×28}{5} + 32

= \frac{252}{5} + 32

= \frac{252+160}{5}

= \frac{412}{5}

(iii) t(-10) = \frac{9}{5} × (-10) + 32

= \frac{-90}{5} + 32

= -18 + 32

= 14

(iv) t(C) = 212

212 = \frac{9}{5} × C + 32

\frac{9}{5} × C = 212 - 32

C = \frac{180×5}{9}

= 100
