Problem 5

<h3>Answer:   6i</h3>

------------------

Explanation:

We have these four identities

  • i^0 = 1
  • i^1 = i
  • i^2 = -1
  • i^3 = -i

Notice how computing i^4 leads us back to 1. So i^4 = i^0. The pattern repeats every 4 terms. So we divide the exponent by 4 and look at the remainder. We ignore the quotient entirely. We can see that 28/4 = 7 remainder 0. Meaning that i^28 = i^0 = 1.

We can think of it like this if you wanted

i^28 = (i^4)^7 = 1^7 = 1

Then the sqrt(-36) becomes 6i

So overall, we end up with the final answer of 6i

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

Problem 6

<h3>Answer:  -3i</h3>

------------------

Explanation:

We'll use the ideas mentioned in problem 5

46/4 = 11 remainder 2

i^46 = i^2 = -1

sqrt(-9) = 3i

The two outside negative signs cancel out, but there's still a negative from -1 we found earlier. So we end up with -3i

In other words, here is one way you could write out the steps

-i^{46}*-\sqrt{-9}\\\\-i^{2}*-3i\\\\i^{2}*3i\\\\-1*3i\\\\-3i\\\\

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

Problem 7

<h3>Answer:   -1</h3>

------------------

Work Shown:

i^10 = i^2 because 10/4 = 2 remainder 2

i^19 = i^3 because 19/4 = 4 remainder 3

i^7 = i^3 because 7/4 = 1 remainder 3

Again, all we care about are the remainders.

i^{10}+i^{19} - i^{7}\\\\i^{2}+i^{3} - i^{3}\\\\i^{2}\\\\-1

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

Problem 8

<h3>Answer:    -1 + i</h3>

------------------

Work Shown:

i^22*i^6 = i^(22+6) = i^28

Earlier in problem 5, we found that i^28 = i^0 = 1

So,

i^1 - \left(i^{22}*i^{6}\right)\\\\i^1 - i^{28}\\\\i^1 - i^{0}\\\\i - 1\\\\-1+i

Which of the following disjunctions is false ?
notsponge [240]
A disjunction is false if both parts of the disjunction are false; otherwise, it is true
----------------------------------------------
Choice A

4-3=2 is false
6*3=9 is false

both parts are false, so overall the entire disjunction is false
----------------------------------------------
Choice B

5*6=30 is true
3+4=7 is true

Neither part is false, so overall the entire thing is true
----------------------------------------------
Choice C

8+3=11 is true
5*4=23 is false

While second piece is false, the overall disjunction is true. The first part (true) makes the whole thing true.
----------------------------------------------
Choice D

7+6=13 is true
5*2=10 is true

Neither part is false, so overall the entire thing is true
----------------------------------------------
----------------------------------------------
In summary, we have

A. False
B. True
C. True
D. True

Making choice A the only answer that is false. So choice A is the final answer

How many favorable outcomes are expressed in the fraction 12/5
Scilla [17]

Answer:

The number of favorable outcomes is 5

Step-by-step explanation:

<u><em>The correct question is</em></u>

How many favorable outcomes are expressed in the fraction 5/12

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.  

The size of the event space is the number of outcomes in the event you are interested in or the number of favorable outcomes

The size of the sample space is the total number of possible outcomes  

 In this problem we have

\frac{5}{12}

therefore

The number of favorable outcomes is 5

The total number of possible outcomes is 12
