9514 1404 393

Answer:

  A.  6

Step-by-step explanation:

The wording "set A and set B" means you're interested in elements that belong only to both. In your diagram, that is Region II. There are 6 elements that belong to A and B.

  AB = 6

_____

<em>Additional comment</em>

"A and B" is also called the "intersection" of the two sets: A ∩ B.

The number you have chosen is the number in Regions I, II, and III. That is the set of elements that belong to A <u>or</u> B. You have identified the "union" of the two sets: A ∪ B. (It might also be represented as A+B.)

HELP PLS<br><br> The function of F is defined by f(x)=x+2<br> find F(n-4)
viktelen [127]

The function of F is defined by f(x) = x + 2, the value of f(n - 4) is given as f(n - 4) = n - 4 + 2 = n - 2

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Given the equation:

f(x) = x + 2

The value of f(n - 4) is given as:

f(n - 4) = n - 4 + 2 = n - 2

The function of F is defined by f(x) = x + 2, the value of f(n - 4) is given as f(n - 4) = n - 4 + 2 = n - 2

Solve 6^x=1,296<br><br><br> X=__________a0
Troyanec [42]

Answer:

x=4

Step-by-step explanation:

6^x = 1296

Take the log base 6 on each side

log6(6^x) = log6(1296)

Rewrite 1296 as 6^4

x = log 6(6^4)

We know that log( a^b) = b log (a)

x = 4 log6(6)

We know that loga(a) =1

x = 4 *a

x =4
