<em>Mathematics is the study of numbers, shapes and patterns. The word comes from the Greek word "μάθημα" (máthema), meaning "science, knowledge, or learning", and is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada)</em>

Which function rule is a rational function x/2 x-2/4 x-2/2 2/x
AURORKA [14]
This expression of yours is problematic in that it's difficult to know which math operations are intended and in which order.   In   <span>x/2 x-2/4 x-2/2 , which part of the expression is in the numerator, and which in the denominator?

x shows up 3 times.  Apparently you meant "the variable x" in "x/2."  What about the next "x?" Did you type that in to indicate multiplication or is that "x" a variable also?  I think you catch my drift:  Your post will need some editing before your readers can understand what you want to do here.

Suppose I interpret your   </span><span>x/2 x-2/4 x-2/2  to mean the following:

( x/2 )
---------- * (x-2/2).  If that wasn't your intent, please fix it.
 x - 2/4

If this interpretation is correct, then you have

      x(x-1)          2x(x-1)
---------------- = ------------.  If not, please fix it.  This rational function
     x-1/2            2x -1        cannot be reduced.</span>

Find the area of a circle that has a diameter of 11 inches. Approximate Π as 3.14. Round your answer to the nearest hundredth.
Alexus [3.1K]

Answer: 94.99 in^2

Step-by-step explanation: The equation for the area of a circle is A=πr^2. To solve this, we need to find the radius. The diameter is the whole circle, whole the radius is half. So divide the diameter by 2.

11/2 = 5.5

The radius is 5.5 inches. Plug the radius into the equation.

A=π5.5^2

Square the 5.5 first. You will get 30.25.

A=π30.25

Plug in 3.14 for pi.

A=3.14 x 30.25

Multiply.

A=94.985

Round to the nearest hundredth.

A=94.99

The area of the circle is 94.99 in^2.
