Explain how to determine which numbers must be excluded from the domain of a rational expression. Please provide an example with

Katarina [22]

Answer:

When we are having a rational expression i.e. a expression of the type:

$\dfrac{f(x)}{g(x)}$

Where f(x) and g(x) are polynomial functions.

Now the domain of this rational expression is whole of the real numbers except the points where the function g(x) will be zero.

Hence we have to exclude the points where the given denominator quantity is zero.

Let us consider an example as:

Let R(x) denote the rational function as:

$R(x)=\dfrac{x^2}{(x-2)(x-3)}$

Now the domain of this rational function will be whole of the real line minus the points where the denominator is zero.

We know that (x-2)(x-3) is zero when x=2 or x=3.

Hence, the domain of R(x) is: R- {2,3}.

1/2 mile in 1/26 hour

aleksandr82 [10.1K]

Answer:

1 hour = 13 miles

Step-by-step explanation:

For every 1/26 hours, you travel 1/2 miles

How many miles will you travel in 1 hour?

Well, let's find out!:

1/26 hours = 1/2 miles

1 hour = 1/2 ÷ 1/26

1 hour = 1/2 • 26

1 hour = 13

For every hour, you travel 13 miles :)

Hope this solves your question! :)

Calculate the area of each shape below. Figures are not drawn to scale.

STatiana [176]

Answer:

The area of the triangle is 168 meters

Step-by-step explanation:

Formula to find the area of a triangle:

Area = 1/2 Base x Height

So, first you need to identify the base and the height. The base is 16m + 8m, and the height is 14m. All you have to do is plug in the numbers:

Area = 1/2 (16 + 8) x 14

Then, you solve:

Area = 1/2 (16 + 8) x 14

Area = 1/2 24 x 14

Area = 1/2 336

Area = 168 meters

So, the area of the triangle is 168 meters
