60 percent as a decimal is 0.6 (60/100) so to find 60 percent of 50 you do 50 * 0.6 and you’ll get 30

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

KIM [24]

Answer:

The probability that the system function is 0.6156

Step-by-step explanation:

We can calculate the chances of two or more independent events by multiplying the chances.

Since the chances of fail are given, to get the chance of pass, we subtract from 1.

Probability that it works = 1 - prob that it fails

For A (probability of fail = 0.10)

Probability that it works = 1 - 0.10 = 0.9

For B (probability of fail = 0.05)

Probability that it works = 1 - 0.05 = 0.95

For C (probability of fail = 0.10)

Probability that it works = 1 - 0.10 = 0.9

For D (probability of fail = 0.20)

Probability that it works = 1 - 0.20 = 0.8

Therefore, the probability that the system function is:

0.9 * 0.95 * 0.9 * 0.8 = 0.6156

Approximately, the probability can be written as 0.6 to one decimal place.
