What is the square root of -1​

Mathematics
1 answer:
Romashka [77]3 years ago
3 0

Answer:

i

Step-by-step explanation:

Now, before you think I'm just stealing points, let me explain. The square root of a number is the number that, if you multiply it by itself, it equals that number. The square root of 4 is 2, because 2 * 2 = 4.

Also, a negative number times another negative number, is a positive number. -2 * -2 = 4

With both of those true, then what number could be multiplied by itself to equal a negative number? i.

i is a weird number that I don't really know how to explain all that well. I am sorry, but that is all that I can give you. i is very complex and has various different equivalents, and different meanings, but i is equal to \sqrt{-1}.

Hope that this helps!

A mixed number greater than 8.45? my answers are A. 8 3/8 <br> B. 8 4/9<br> C. 8 3/5 <br> D. 8 5/12
ASHA 777 [7]
8.45 = 8 45/100 = 8 9/20 = 169/20

A. 8 3/8 = 67/8
B. 8 4/9 = 76/9
C. 8 3/5 = 43/5
D. 8 5/12 = 101/12

The common denominator of all those fractions is 360, so we can write them as:

8.45 = 3042/360

A. 8 3/8 = 3015/360
B. 8 4/9 = 3040/360
C. 8 3/5 = 3096/360
D. 8 5/12 = 3030/360

As a mixed numbers:

8.45 = 8 162/360

A. 8 3/8 = 8 135/360
B. 8 4/9 = 8 160/360
C. 8 3/5 = 8 216/360
D. 8 5/12 = 8 150/360

Now we can easily see that only 8 216/360 is greater than 8 162/360. It means the correct answer is C: From the given mixed numbers, only 8 3/5 is greater than 8.45.

How many terms are in the arithmetic sequence 5, 1, −3, . . . , −111?
masya89 [10]
Here, it helps to find a general expression for the nth term in the sequence. Since the sequence is arithmetic, the general term is a_n = a + bn, where b is the common difference. By inspection of the first few terms we see the common difference is -4. Then by solving a_1 = a - 4x1 = 5, we obtain a = 9, so the nth term is: a_n = 9-4n. We then solve a_n=-111 for n, so 9-4n=-111. Rearranging, we get 4n=9+111, or 4n=120, or n=30. Thus there are 30 terms in the sequence.
