What is the value of (-7 + 3i) - (2-6i)?

Mathematics

BigorU [14]3 years ago
4 0

First you must distribute the minus sign to the number bolded bellow:

(-7 + 3i) - (2 - 6i)

(-7 + 3i) + (-2 + 6i)

-7 + 3i - 2 + 6i

Now you must combine like terms. Imaginary numbers can only combine with imaginary and real number can only be combined with real numbers:

(-7 + (-2) ) + (3i + 6i)

-9 + 9i

I hope this helped! Let me know if you have any questions :)

A drawer contains loose socks. There are 2 blue and 4 black socks in the drawers. What is the probability that you choose a sock
stepladder [879]

The probability is p = 2/5, the correct option is the third one.

<h3>How to find the probability?</h3>

There is a total of 6 socks, such that 4 are black and 2 are blue.

Then the probability of first getting a black sock is the quotient between the number of black socks and the number of blue socks, which gives:

P = 4/6

Now there are 5 socks in total, such that 3 are black and 2 blue.

Then the probability of getting another black one is:

Q = 3/5

The joint probability (getting the two black socks) is given by the product of the individual probabilities:

p = (4/6)*(3/5) = 2/5

The correct option is the third one.

Raining Company analyzes its receivables to estimate bad debt expense. The accounts receivable balance is $200,000 and credit sa
8_murik_8 [283]

Answer:

Raining Company and Tanning Company

An Uncollectible Expense of $17,500 will be credited to the Allowance for Doubtful Accounts to bring the credit balance to $20,000.

Step-by-step explanation:

Since the accounts receivable balance is $200,000, there is nothing to do with the credit sales of $1,300,000.

The Allowance for Doubtful Accounts after adjustment should have a credit balance of $20,000 ($200,000 x 10%).

With a credit balance of $2,500 before adjustment, it will be adjusted (credited) with Uncollectible Expense of $17,500.  This brings the adjusted balance to $20,000 which represents 10% of the accounts receivable balance of $200,000.

Note that the Allowance for Doubtful Accounts is a contra (credit) account to the Accounts Receivable account.  This allowance is a way to prudently provide for credit risk as required by Generally Accepted Accounting Principles.
