Mathematics
1 answer:
const2013 [10]2 years ago
4 0

Answer:

A

Step-by-step explanation:

Here, we want to find the value of ln (-7)

ln is same as Log to base e and mathematically , we have it for positive numbers only

For that of negative numbers, we get undefined results

However, by the use of special mathematical

methods, we have the answer for ln (-7) as;

1.94591015 + 3.14159265 i

As we can see, for the second part, the value for the coefficient of the complex number is pi and thus, we have the correct option as A

kiruha [24]

Answer:

6

Step-by-step explanation:

Rule for divisibilty of 6:

  • sum of place values is a multiple of 3
  • an even number

Step 1: dd the integers

  • 7 + 6 + 8 + 7 + 2 + x
  • 30 + x

Now, we have a couple options:

  • x = 3
  • x = 6
  • x = 9

You can use any of these three values,

But the number has to be even, so the last digit has to be even. The correct answer is 6.

Please help ASP!!!! A= positive, B=Negative, C=Zero​
Evgen [1.6K]

Answer:

B. Negative

Step-by-step explanation:

So first, we want to locate the variable.

y (x/y) = (y/1) (x/y)

           = (xy/y)

           = x

The y/y cancels out and now we know we need to find the sign of x. Because x is to the left of 0, it's negative. Anything to the left decreases and anything to the left of 0 is (-).

James has a bag 77 of nickels and dimes. The total value of coins is $6.60. How many dimes does James have?
tatuchka [14]

James has 55 dimes in the bag

Step-by-step explanation:

The given is:

  • James has in a bag 77 of nickels and dimes
  • The total value of coins is $6.60

We need to find how many dimes James has

Assume that the number of nickels is x and the number of

dimes is y in the bag

∵ There are x nickels in the bag

∵ There are y dimes in the bag

∵ There are 77 coins in the bag

∴ x + y = 77 ⇒ (1)

∵ 1 nickel = 5 cents

∴ The value of nickles in the bag = 5x cents

∵ 1 dime = 10 cents

∴ The value of dimes in the bag = 10y cents

∵ The total value of coins is $6.60

∵ 1 dollar = 100 cents

∴ $6.60 = 6.60 × 100 = 660 cents

∴ 5x + 10y = 660 ⇒ (2)

Now we have a system of equations to solve it

Multiply equation (1) by -10 to eliminate y

∵ -10x - 10y = -770 ⇒ (3)

- Add equations (2) and (3)

∴ -5x = -110

- Divide both sides by -5

∴ x = 22

Substitute the value of x in equation (2) to find y

∵ 22 + y = 77

- Subtract 22 from both sides

∴ y = 55

∴ The number of dimes is 55

James has 55 dimes in the bag
