Write as a single logarithm
Anettt [7]

ANSWER

c. \ln( \frac{2 {x}^{3} }{3y})

EXPLANATION

We want to write

ln(2x)  + 2 ln(x)  -  ln(3y)

as a single logarithm.

Use the power rule to rewrite the middle term:

n \:  ln(a)  =  ln( {a}^{n} )

ln(2x)  +  ln( {x}^{2} )  -  ln(3y)

Use the product rule to obtain:

ln(a)  +  ln(b)   =  ln(ab)

ln(2x \times  {x}^{2} )-  ln(3y)

ln(2{x}^{3} )-  ln(3y)

Apply the quotient rule:

ln(a)  -   ln(b) = ln( \frac{a}{b})

ln(2{x}^{3} )-  ln(3y) =\ln(\frac{2 {x}^{3} }{3y})

Two dice are thrown simultaneously find
STALIN [3.7K]

Answer:

13.89%

Step-by-step explanation:

First lets find all possibilities of two dice being thrown, we can do this by finding a simple dice chart online (I attached an image of one to help.)

There are 36 possibilities, and we need to find how often the two dice add together to equal eight. 6+2=8, 5+3=8, etc.

There are five 5 total times that two dice can equal eight. so 5 out of 36 times we roll two dice we'll get eight.

\frac{5}{36}

Type that into the ol' handy dandy calculator and we've got 0.1388888889. So... a lot of 8's, we don't need that many and we just can't have an answer with that many.

To make that number into a percentage we have to move the dot two spaces over, and round to the thousandths place (two numbers).

This would give us 13.89%, our final answer.

Hope this helped!

Evaluate the following expressions using the chip method. SHOW ALL WORK!!!
Mila [183]

Answer:

  • a. -7
  • b. -20
  • c. 7

Step-by-step explanation:

  • a. -9+2, in this case, it is -7 because you take the bigger number and subtract it by the lower number. If the bigger number is negative your answer will be negative, if the bigger number is positive it will be positive it is just really a basic subtraction problem just add the sign.
  • b. In multiplication +++=+ ++-=- and a -+-=+ do your problem without thinking about the signs and then add the signs with the formula I showed you.
  • c. ---=+

Hope this helps :)!
