Can some please help

Use linear approximation to approximate √49.4 as follows.

Let \( f(x) = \sqrt{x} \). The equation of the tangent line to \( f(x) \) at \( x = 49 \) can be written in the form \( y = mx + b \). Compute \( m \) and \( b \).

\[ m = \boxed{} \]

\[ b = \boxed{} \]

Using this find the approximation for \( \sqrt{49.4} \).

Answer:

\[ \boxed{} \]
