Z^5=-7776i

Mathematics
1 answer:
Sloan [31]3 years ago
7 0

Answer:

Z=+6

Step-by-step explanation:

Z^5=-7776i

Let's note that i I mathematics means negative one i.e

i = -1

So the equation is equal to

Z^5=-*-(7776)

Z^5 = 7776

Z= 5√7776

Since it's a divisible by 6

It's giving us a clue that 6 it's the answer.

Ok let's check the 5th root of 7776 in our calculator.

Z=+6

+6 is the solution to the equation

Z^5=-7776i

PLEASE I AM ASKING FOR HELP DESPERATELY! Which is NOT a good reason to establish a positive credit history?
otez555 [7]

Answer:

B.

Step-by-step explanation:

The purpose of establishing a good credit history is to show that you are able to handle money. The higher your credit score is, the more responsible you are with money.

You can build good credit history by making payments with a credit card and repaying your purchases. It shows that if the bank were to give you a larger sum of money, you would pay it back.

As such, B is incorrect. The purpose of credit relates to purchases. A is obviously correct for this reason. C is correct because banks are likely to put less interest, as interest correlates to the score (lower credit score, higher interest). D is correct because banks allow you to obtain credit cards with better rates if your credit score is high enough.

Employers cannot determine your qualification for a job based on a credit score. Some states even prohibit this. For this reason, B is incorrect.

Choose the correct comparison for the numbers below.
Alexandra [31]

Answer:

A

Step-by-step explanation:

In order to compare all three numbers, you must change them all to have the same form, either all decimal form, all fraction, or all percentages.

The easiest ways to compare are decimal and percentage, as they're practically the same thing. For simplicities sake, though, let's turn all the numbers into decimal.

Since 0.85 is already in decimal form, leave it as it is.

3/4 can be turned into a decimal by putting it into a calculator, but intuitively you should know that it's 0.75. If you don't know a fraction intuitively, you just need to make the fraction into a multiple of denominator 100 and take the numerator. For example:

\frac{3}{4} * \frac{25}{25} = \frac{75}{100}

Numerator is 75.0, now simply move the decimal place up to to get the decimal form 0.75.

91% can be changed into a decimal by moving the decimal place left 2 places. 91.0% turns into 0.91.

Now that you can see the numbers, just rearrange them from least to greatest

0.75<0.85<0.91

equal to A

Correct I’ll give brainlist no links or I’ll report
Vera_Pavlovna [14]

Answer:

y = 8x - 64

Step-by-step explanation:

Start with y = mx + b, the slope-intercept equation.  Replace m with 8, x with 7 and y with -8:

-8 = 8(7) + b, or

-8 - 56 + b, or

b = -64

Then the desired equation is

y = 8x - 64
