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}}

PLEASEE help I’m really confused
maksim [4K]

Answer:

\frac{13}{\sqrt5}

Step-by-step explanation:

To get the shortest distance from a point to a line, we need to find a perpendicular line that intersects the line and also intersects the line. We know the slope of the line will be 1/2, but to find the y-intercept, we can just plug it into the point because we already know it will be on the line.

-3 = 1/2(-2)+c

-3 = -1+c

-2 = c

Now, we know the slope and the y-intercept, and since it will intersect the other line, we can set it equal to the other lines formula:

1/2x-2 = -2x+6

5/2x=8

x=16/5

Now, plugging this value of x into any of the equations, we can find the y-coordinate:

16/5(1/2)-2 = -2/5

We have the point (16/5, -2/5)

Now, we need to find the distance between (-2, -3) and (16/5, -2/5)

Plugging into distance formula:

\sqrt{(-2 - \frac{16}{5})^2+(-3-(-\frac{2}{5}))^2}\\=  \sqrt{(-5.2)^2+(-2.6)^2}\\= \sqrt{33.8}

= =\frac{13}{\sqrt5}
