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:
y=
x-4
Step-by-step explanation:
is the slope (rise over run)
-4 is the y-intercept
Answer:
Option A) 1.6t+0.5
Step-by-step explanation:
Let
t ----> the number of trophies
we know that
To determine the total weight of the box, multiply the number of trophies by the weight of each trophy and add the weight of the empty box.
The linear equation that represent this problem is
As what I can observe, the pathway can be formed with 2 right triangles. Thus, I'll get the area of the 2 right triangles and multiply its area by the paving cost per square meter.
Area of Right Triangle: ab / 2
a = 6 2/3 m ⇒ 20/3 m; b = 3m
Area of 1 triangle= (20/3 m * 3 m) ÷ 2 = 20 ÷ 2 = 10 m²
Area of 2 triangles = 10m² * 2 = 20 m²
Total cost = $40 * 20m² = $800
Answer:
C: 7
Step-by-step explanation:
Total number of tickets = 35
Tickets sold = 28
Tickets left = 35 - 28
Answer = 7
