The function `t` which maps temperature in degree Celsius into temperature in degree Fahrenheit is defined by `t(C)=(9C)/5+32`.Find (i) `t (0)` (ii) `t(28)` (iii) `t(-10)` (iv) The value of C, when `t(C) = 212`.

Explanation

To solve the problem step by step, we will evaluate the function \( t(C) = \frac{9C}{5} + 32 \) for the given values of \( C \).

### Step-by-Step Solution:

1. **Finding \( t(0) \)**:
- Substitute \( C = 0 \) into the function:
\[
t(0) = \frac{9 \times 0}{5} + 32 = 0 + 32 = 32
