A square is inscribed in a circle . If the area of the square is 9 inch square what is the ratio of the radius of the circle to
OLga [1]

Answer:

  (√2)/2

Step-by-step explanation:

The ratio of the radius of the circle to the side of the inscribed square is the same regardless of the size of the objects.

The radius of the circle is half the length of the diagonal of the square. For simplicity, we can call the side of the square 1, so its diagonal is √(1²+1²) = √2 by the Pythagorean theorem. The radius is half that value, so is (√2)/2. The desired ratio is this value divided by 1.

Scaling up our unit square to one with a side length of 3 inches, we have ...

  radius/side = ((3√2)/2) / 3 = (√2)/2

_____

A square with a side length of 3 inches will have an area of (3 in)² = 9 in².

How to find the slope from a table of data
sammy [17]

The slope of a linear line (or a linear equation) can be found by simply taking 2 values for x and y and then using the slope formula which is \frac{dy}{dx} or:

\frac{y_{2} - y_{1}}{x_{2} - x_{1}}

Example:

Let's say you're give this table:

x: 1, 2

y: 1, 2

Following the steps which I gave, you take 1 value for the y (preferably the larger one) which in this cause will be 2 and then another y from the table which would be 1

Do the same for x

Now plug the values taken in the slope formula and you get:

\frac{2 - 1}{2 - 1}

\frac{1}{1} = 1

Therefore the slope is 1.
