Answer:
{∅, {a}, {b}, {a,b}}
Step-by-step explanation:
The value of power of a set is generalized by using the formula,
Power of a set (P) = 2^n where n is the number of element in the set.
Given two distinct elements a and b say;
A = {a,b}
n(A) = 2 i.e the number of elements in the set is 2. Therefore the power of the set will be 2^n which gives 2^2 = 4.
P(A) = 4 means there are 4 subsets of the given set. Subsets are sets of elements that can be found in the set. The subsets of element A will be;
{∅, {a}, {b}, {a,b}} which gives 4 elements in total.
Note that empty set ∅ is always part of the subset of any given set
Answer:
To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:
"d" represents the distance and coordinates are expressed as follows: (x, y)
Let's go to the calculations.
The answer is 12,6 u.c.
Step-by-step explanation:
Answer:
43, 40
Step-by-step explanation:
1) Exterior angles are equal.
(x + 44) = 87 --> 87 - 44 = 43
x = 43
2) Alternate interior angles are equal.
(x - 30) = 70
x = 40

Answer:
Step-by-step explanation:
The function p is an absolute value equation p(x)=|x| or it could be described as the sqare root of x squared.
q(x) could be the negative of p(x) raised by two units
q(x)=-|x|+2
