<h3>4 Answers: A, C, E, and F</h3>

================================================

Explanation:

Choice A is true assuming we have a_n = (-1)^n*b_n

In this case, a_n = (-1)^n*\frac{1}{\sqrt{n}} and b_n = \frac{1}{\sqrt{n}}

--------

Choice B is false. See choice A above.

--------

Choice C is true. The sequence \{b_n\} is decreasing. As n gets larger, b_n gets smaller. This is because the denominator is growing larger with the numerator held constant.

--------

Choice D is false. This contradicts choice C.

--------

Choice E is true since the denominator is growing forever

This is similar to  \displaystyle \lim_{n \to \infty} \frac{1}{n} = 0

--------

Choice F is true due to choices C and E being true.  

--------

Choice G is false because it contradicts choice F.

If F(x)=3x-2/6 which of the following is the inverse of F(x)?
lana66690 [7]

Answer:

Step-by-step explanation:

I'm seeing that f(x) is

\frac{3x-2}{6}

What you do to find an inverse is switch the x and y coordinates and then solve for the new y.  Switching the x and y gives us:

x=\frac{3y-2}{6}

Now we have to solve for the new y.  Begin by muliplying both sides by 6 to get:

6x = 3y - 2 and

6x + 2 = 3y so

2x + 2/3 = y

To put it back into function notation:

f^{-1}(x)=2x+\frac{2}{3}

At the 6th grade school dance there are 132 boys, 88 girls and 14 adults. What is the ratio of boys to girls
spayn [35]
The adult's genders aren't specified so that doesn't matter.

There are 132 boys for every 88 girls

(132:88) 

To simplify the ratio, divide both numbers by the GFC (Divide both sides by 44)

3:2 

There are 3 boys for every 2 girls
