Find the distance between (-1,-2) and (8,9)

Rom4ik [11]

Answer:

$\sqrt{202}$ units or 14.2 units (rounded to the nearest tenth)

Step-by-step explanation:

To find the distance between a pair of two points, use the distance formula $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ . Substitute the x and y values of (-1,-2) and (8,9) into the formula and simplify:

$d = \sqrt{(-1-8)^2+(-2-9)^2} \\d = \sqrt{(-9)^2+(-11)^2} \\d = \sqrt{81+121} \\d= \sqrt{202}$

So, as an exact answer, the distance is $\sqrt{202}$ units.

(To find the decimal approximate of that answer, enter it into a calculator. This would make the decimal approximate 14.2 units, when rounded to the nearest tenth.)

We know that the true value for pi is given as 3.14156.

Now, we have been given that the approximate value for pi is 3.141

We know the formula

Absolute error, $\Delta x = | \text{True value } - \text{ Approximate value} | \\
\\
\Delta x =|3.14156-3.141|\\
\\
\Delta x =0.00056$

Relative error is given by

$\text{Relative error }= \frac{\Delta x}{\text{true value} }\\
\\
\text{Relative error }=\frac{0.00056}{3.14156} \\
\\
[tex]\text{Relative error }=0.000178$

The percentage error is given by

$\text{Relative error } \times 100\\ 
\\ 
0.000178\times 100 
\\ 
=0.0178 \%$
