Let A= {a,b,c,d,e} and let B= {1,2,3,4,5} determine n(AxB)

777dan777 [17]

n(AxB) = 25

Step-by-step explanation:

AxB in sets is called Cartesian product. And is defined as a set of ordered pairs (a,b) where a belongs to A and b belongs to B.

Given

A = {a,b,c,d,e}

B = {1,2,3,4,5}

The number of elements for Cartesian product of two sets is determined by:

$n(AxB) = n(A) * n(B)$

Here

$n(A) = 5\\n(B) = 5$

So,

$n(AxB) = 5*5 = 25$

Hence,

n(AxB) = 25

What is the answer to this question?

sukhopar [10]

First plug in f and g:
$3 x^{2} +1- [1-x]$
Then distribute $3 x^{2} +1-1+x$
Combine like terms
$3 x^{2} +x$
Now plug in 2 for x
$3( 2^{2} )+2$
3(4)+2=12+2=14

Hope that helps

How do you solve this kind of equation? 9(x+2) > 9(x-3)

GalinKa [24]

Step-by-step explanation:

okay so that's an inequality. You solve it the same way you saw the regular equation. the only difference is that if you divide or multiply by a negative number then you have to turn the sign around.
