<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.

What mixed numbers are equivalent to −1. 5/6 ​ and ​ ​ −1. 7/9 ​ and use the LCD? Enter your answers in the box. if it helps the
Vlada [557]

Answer: -1.5/6 = -1/4; -1.7/9 = -17/90


Step-by-step explanation: Yeah, I'm not exactly sure what the problem is asking for, but this how I interpreted it. Use the LCD of the fractions -1.5/6 and -1.7/9 to find equivalent fractions with integer numerators and denominators.

For me, LCD doesn't help with solving the problem that much.

But anyways, the first fraction, -1.5, can be turned in an integer if you multiply the entire fraction by 2. So the result would be -3/12. You can simplify this to -1/4.

The second fraction, when multiplied by 10 yields -17/90. 17 is a prime number and is not a factor of 90, thus the equivalent fraction of -1.7/9 is 17/90.

Hope this helped.
