Answer: A. All real numbers
Step-by-step explanation:
Find fg;
f(x) * g(x) = (x + 2) * ( 1 / x + 2)
= ( x + 2) / (x + 2)
= 1
In giving 1 as the product, the domain of fg is any real number.

Alexis reads 1/2 of a short story in five minutes. How many short stories could she read per hour?
Answer:
6 stories
Step-by-step explanation:
1 hour = 60 minutes
We can use a ratio to solve
1/2 story x story
------------- = ------------
5 minutes 60 minutes
Using cross products
1/2 * 60 = 5 * x
30 = 5x
Divide each side by 5
30/5 = 5x/5
6 =x
Which expressions are factors of the expression
-24xyz - 12xy + 20xyz
Answer:
xy
2xy
4
Step-by-step explanation:
A factor is a number of term you can factor out of each part of the expression/ or divide it by.
In -24xyz - 12xy + 20xyz
All three parts have xy, so it is a factor
All three don't have 12xz, because -12xy doesn't have z variable for instance.
All three have 2xy.
All three can't factor out 3y, because you can't divide 20 by 3 nicely.
All three can't factor out 4yz, because middle term -12xy doesn't have z.
All three can't factor out 12, because you can't nicely divide 20/12.
All three can factor out 4, because -24, -12, and 20 are all divisible by 4.

A reflector on the inside of a certain flashlight is a parabola given by the equation y = x2– 25. Find the points where
the reflector meets the lens by finding the values of x when y = 0.
Answer:

Answer:
(4.75, 2.25)
Step-by-step explanation:
When reflected across the x-axis, the y-coordinate becomes its opposite.
So if the pair given was after the reflection, the original will have the same x-value, and the opposite y-value.
(4.75 , -2.25) = (4.75 , 2.25)

The area of a square is 144 cm' and one of
its sides is (x + 2) cm. Find x and then theside of the square
Answer:
The side of the square is 12 cm and x = 10 cm.
Step-by-step explanation:
Since it's a square, it's sides have the same length.
Hence, since one of it's sides is x + 2, the other side must be x + 2 as well.
Therefore, we can set up an equation:
[tex](x + 2)^{2} = 144 cm^{2}[/tex]
[tex](x + 2) = \sqrt{144cm^{2}}[/tex]
[tex]x + 2 = 12 cm[/tex]
[tex] x = 10 cm[/tex]
Hence, the side of the square is 12 cm and x = 10 cm.

O sales tax
O corporate tax
O marginal tax
O personal property tax
Answer:

Step-by-step explanation:
Claude owns a store. Every year, he pays corporate tax. Option B is correct.
Claude owns a store. Every year, he pays _____.
Black space to be filled from the following option,
A. sales tax B. corporate tax C. marginal tax D. personal property tax
A corporate tax is a tax levied on the net gain of an enterprise that is taxed at the commodity level in a particular mark. Net gain for corporate tax is commonly the financial statement of net gain with transformations and may be defined in detail in the tax system of each country.
Since the store owner mostly pays the corporate tax besides there, sales tax is paid by the company owners, marginal tax is also paid by the production companies, and personal property tax is paid by any person.
Thus, Claude owns a store. Every year, he pays corporate tax. Option B is correct.

If 51% of a population will vote for Candidate A in an election, what is the probability that in a random sample of 75 voters, fewer than 50% of the sample will vote for Candidate A
Answer:
The value is [tex]P(X < 0.50 ) = 0.43133[/tex]
Step-by-step explanation
From the question we are told that
The population proportion is p = 0.51
The sample size is n = 75
Generally given that the sample size is large enough (i.e n > 30) the mean of this sampling distribution is mathematically represented as
[tex]\mu_x = p = 0.5 1[/tex]
Generally the standard deviation of this sample distribution is mathematically represented as
[tex]\sigma = \sqrt{\frac{p(1- p)}{ n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{0.51 (1- 0.51 )}{75} }[/tex]
=> [tex]\sigma = 0.058[/tex]
Generally the probability that in a random sample of 75 voters, fewer than 50% of the sample will vote for Candidate A is mathematically represented as
[tex]P(X < 0.50 ) = P( \frac{ X - \mu_x }{\sigma } < \frac{ 0.50 - 0.51 }{0.0578 } )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
=> [tex]P(X < 0.50 ) = P( Z < -0.1730 )[/tex]
From the z table the area under the normal curve to the left corresponding to -0.1720 is
[tex]P( Z < -0.1730 ) = 0.43133[/tex]
So
[tex]P(X < 0.50 ) = 0.43133[/tex]
