Answer:

  see below

Step-by-step explanation:

<em>Which of the equations from part A represent adding two rational numbers?</em>

  Equations A, C, E

<em>What hypothesis can you make about the sum of two rational numbers?</em>

  The sum of two rationals will always be rational

<em>Will the addition result in a rational or an irrational number?</em>

  Our hypothesis is that the result is always rational. This can be justified by the fact that the sum of two rationals a/b + c/d, where a, b, c, d are integers and bd≠0, is (ad+bc)/(bd), a rational, based on closure of integers for multiplication and addition.

<em>Which equations represent the sum of a rational and an irrational number?</em>

  Equations B, F

<em>What hypothesis can you make about the sum of an irrational and a rational number?</em>

  The sum of a rational and irrational number is always irrational.

Examine the pattern in the powers of i you wrote in the table, and create a rule for finding the value of large powers of i. Jus
denpristay [2]
Let N be any integer. Then

i^N=\begin{cases}1&\text{if }N\equiv0\mod4\\i&\text{if }N\equiv1\mod4\\-1&\text{if }N\equiv2\mod4\\-i&\text{if }N\equiv3\mod4\end{cases}

In other words:

(1) If N is a multiple of 4, then i^N=1.

(2) If dividing N by 4 leaves a remainder of 1, then i^N=i, since i^N=i^{4n+1} for some integer n, and from (1) we know that i^{4n+1}=i^{4n}i=i (because, obviously, 4n is a multiple of 4).

(3) If instead you get a remainder of 2, then i^N=-1. This follows from (1) as well. i^N=i^{4n+2}=i^{4n}i^2=(1)(-1)=-1.

(4) Finally, if you get a remainder of 3, then i^N=i^{4n+3}=i^{4n}i^2i=(1)(-1)(i)=-i.

When measuring time, 8 concerts are approximately equal to 6 symphonies. How many symphonies are equal to 42 symphonies?
Vinil7 [7]
So normally it is
if 8x is to 6y, then how many x is to 42y?
it could be
if 8x:6y then how many x:42y or
if 8x:6y then how many y:42 x

I will solve for both

if it is
x:42y go to AAAAAAAA
if it is
y:42x then go to BBBBBBBBBB


AAAAAAAA
 how many concerts are equal to 42 symponies
arrange in concerts to symponies format

8:6=x:42
fractionify
8/6=x/42
multiply boht sides by 42
336/6=x
56=x
56 concerts equals 42 symponies



BBBBBBBBBB

 how many  symponies are equal to 42 concerts
areange in symponies:concerts
6:8=x/42
fractionify
6/8=x/42
multiply boht sides by 42
252/8=x
31.5=x
31.5 symponies to 42 concerts




so it could be


56 concerts to 42 symponies
or
31.5 symonies to 42 concerts
