Use linear approximation, i.e. the tangent line, to approximate √ 16.2 as follows: Let f ( x ) = √ x . Find the equation of the
Dvinal [7]

The linear approximation to f(x) near x=16 is

L(x)=f(16)+f'(16)(x-16)

We have

f(x)=\sqrt x\implies f(16)=4

f'(x)=\dfrac1{2\sqrt x}\implies f'(16)=\dfrac18

\implies L(x)=4+\dfrac18(x-16)=\dfrac x8+2

Then

f(16.2)\approx L(16.2)\iff\sqrt{16.2}\approx\dfrac{16.2}8+2

\implies\boxed{\sqrt{16.2}\approx4.025=\dfrac{161}{40}}
