For A = {a,b}, determine A x P(A).

Mathematics
1 answer:
alex41 [277]3 years ago
6 0

Answer:

Since A={a,b}, then P(A)=\{\emptyset, \{a,b\}, \{a\}, \{b\}\}. Remember that the Cartesian Product of two sets A, B is defined by

A\times B=\{(x,y): x\in A \text{ and } y\in B\}. Then

A\times P(A)=\{(a,\emptyset),(a,\{a,b\}),(a,\{a\}), (a,\{b\}), (b,\emptyset),(b,\{a,b\}),(b,\{a\}), (b,\{b\})\}

Greeley [361]

Answer:

f = € 0.20

k = € 2.20

Step-by-step explanation:

k + f = 2.40

k = 2 + f

(2 + f) + f = 2.40

2f = 2.40 - 2

2f = 0.40

f = € 0.20

k = 2 + 0.20 = € 2.20
