Answer:

a) A n (B' n C') = {3, 9}.

b) (AUB) n (BUC) = {2,4,5,6,7,8}

Step-by-step explanation:

a) Rewriting C ; C = {4,5,6,7,8}

B' = {3,5,7,9} and C' = {2, 3, 9}

so (B' n C') = {3, 9}

and A n (B' n C') = {3, 9}.

b) {A U B} = { 2,3,4,5,6,7,8,9} and {B U C} = {2,4,5,6,7,8}

so (AUB) n (BUC) = {2,4,5,6,7,8}

4ln x -8=12 its giving me other equations

kogti [31]

The solution of the given logarithmic equation is x = 28.1

<h3>How to solve the logarithmic equation?</h3>

Here we have the logarithmic equation:

4*ln(x - 8) = 12

And we want to solve this for x.

Remember the relations:

$ln(e^x) = x\\e^{ln(x)} = x$

First, we divide both sides by 4:

$ln(x - 8) = 12/4 = 3$

Then, if we apply the exponential equation to both sides of our equation, we get:

$e^{ln(x - 8)} = e^{3}\\\\x - 8 = e^3\\\\x = e^3 + 8 = 28.1$

Answer:

$f(x)=-63xy^8$

Step-by-step explanation:

$f(x)=(-9x^4y^6)(7x^{-3}y^2)$

$f(x)=(-63x^{4-3}y^{6+2})$

$f(x)=-63xy^8$

A Builder is trying to level out some ground with a front end loader. He picks up some excess dirt at (7,17) and then maneuvers

Juliette [100K]

Vectors give us direction and distance. the first part of our ordered pair moves us in the x direction (left and right), and the second member of the ordered pair moves us in the y direction (up and down)

if you plotted each point along the move, you would go from (7,17) and move -1 in the x direction and 0 in the y, ending up at (6,17). From there, we move 2 in the x direction and 7 in the y, to (8,24).

basically we just add all of the x's together and the y's together since we are moving in a specific direction from a point to a new point.

so

x=7+-1+2+2=10
y=17+0+7+10=34

and we end up at (10,34)
