1 answer:

7 0

Multiples of 3 are {3, 6, 9, 12, 15, 18, 21, 24, 27, 30, …….} , these are all the multiples of 3.
Now, we are looking a negative multiple of 3, which means, we need to a negative value of 3 multiples.
=> -3 {-3, -6, -9, -12, -15, -18, -21, -24, -27, -30,…..} These are all the negative multiple of 3 in set builder notation.
Notice, that the numbers are of divisible by 3. Any number that Is divisible by 3 is called multiple of 3.

How do you convert from a radical expression to a rational exponent?

Murljashka [212]

The denominator of the raised fraction is what goes on the outside of the square root. So if you had 2 raised to 1/3, you'd put the 3 raised outside to the left of the radical and the 2 inside. They give the same answer, so if you know one, you can always play with the other until you get the same answer. My teacher told us in Calculus a funny/weird way to remember it is the "bottom (of the raised fraction) goes in the crack (of the radical)." Does this help??

Which of the following geometric series converges?

Artist 52 [7]

All three series converge, so the answer is D.

The common ratios for each sequence are (I) -1/9, (II) -1/10, and (III) -1/3.

Consider a geometric sequence with the first term a and common ratio |r| < 1. Then the n-th partial sum (the sum of the first n terms) of the sequence is

$S_n=a+ar+ar^2+\cdots+ar^{n-2}+ar^{n-1}$
