Approximate the value of each of the irrational numbers below to the nearest thousandth.

Marta_Voda [28]

ANSWER

$\sqrt{13} = 3.606$

to the nearest thousandth.

EXPLANATION

The given irrational number is

$\sqrt{13}$

We use the calculator to evaluate this to obtain,

$\sqrt{13} = 3.605551...$

To round to the nearest thousandth means we are rounding to 3 decimal places.

The third decimal place is 5.

The next number is 5 so we round up.

$\sqrt{13} = 3.606$

Write the equation of this circle in standard form. A) (x - 2)2 + (y - 3)2 = 4

Vika [28.1K]

Answer:

$x^2 + y^2 -4x -6y + 9 = 0$

Step-by-step explanation:

To write a circle in standard form, expand the equation of the circle and move all terms to one side.

$(x-2)^2 + (y-3)^2 = 4\\x^2 -4x + 4 + y^2 -6y + 9 = 4\\x^2 +y^2 - 4x - 6y + 13 = 4\\x^2 + y^2 -4x -6y + 9 = 0$
