Answer:

Option C - F(x)=\frac{1}{x-2}

Step-by-step explanation:

To find : Which of the following rational functions is graphed below?

Solution :

A rational function is defined as function in form of p/q where p and q are integers and q is non-zero.

In examining the graph,

It has a vertical assymptote given by x=2.

So, the curve will contain (x-2) in the denominator.

If we see the options we can say that,

The required function is F(x)=\frac{1}{x-2}.

Therefore, option C is correct.

What is the sum of the rational expressions below?<br> 3x-1/2x + 3x/x-1
Elden [556K]
In order to find the sum of the given rational expressions above, here are the steps.
Firstly, you need to find the LCM of the least common denominator.
So it would look like this: 
<span>3x-1 +   3x            (3x-1)(x-1) + (2x)(3x)
------    -------    =    ---------------------------
  2x       x-1                  2x(x-1)

3x^2-4x+1+6x^2
----------------------
    2x(x-1)
And the final result would be this:
9x^2-4x+1
--------------
  2x(x-1)

</span>9x^2-4x+1
--------------
  2x^2-2x
<span>
Hope that this is the answer that you are looking for.

A random sample of 25 employees of a local company has been taken. A 95% confidence interval estimate for the mean systolic bloo
liraira [26]

Answer:

(B) ​If the sampling procedure were repeated many times, 95% of the resulting confidence intervals would contain the population mean systolic blood pressure.

Step-by-step explanation:

A confidence interval of 95% means that there is a 95% certainty that for a given sample, the population mean will be within the confidence interval estimated.

This is the same as saying that if he sampling procedure were repeated many times, 95% of the time the population mean would be contained in the resulting confidence interval.

Therefore, the answer is B)

A globe has a diameter of 14 inches. Find the volume of the globe. Round your answer to the nearest tenth.
Harrizon [31]

Answer:

1436.8 in³ (nearest tenth)

Step-by-step explanation:

A globe is in the shape of a sphere.

volume \: of \: sphere =  \frac{4}{3} π {r}^{3}

Diameter= 2 ×radius

radius of globe

= 14 ÷2

= 7 inches

Volume of globe

=  \frac{4}{3} π {(7}^{3} ) \\  = 1436.8 \: in^{3}  \\ (nearest \: tenth)

An element with mass 430 grams decays by 27.4% per minute. How much of the element is remaining after 19 minutes, to the nearest
nadya68 [22]
The equation for exponential decay is y=a*b^x, where <em>a</em> is the initial amount, <em>b</em> = 1 + <em>r</em> (the growth rate as a decimal number) and <em>x</em> is the number of time periods (in this case, minutes).  Substituting the information we have:
y=430(1+-0.274)^1^9&#10;\\=430(1-0.274)^1^9&#10;\\=430(0.726)^1^9=0.98.  To the nearest tenth of a gram, this would be 1.0 grams.
