Answer:
{1,3,6,9,12,15,18,24}
Step-by-step explanation:
The union is joining of the elements of the sets
{3, 6, 9, 12, 15}U {1, 6, 12, 18, 24}
= {1,3,6,9,12,15,18,24}
A ∪ B = {1,3,6,9,12,15,18,24}
Let A = {3,6,9,12,15}
B = {1,6,12,18,24}
So,
A ∪ B = {3,6,9,12,15} ∪ {1,6,12,18,24}
(1,18)
use a graphing calculator to graph the function
then, graph all the coordinates given and find on that's on the graph
It is A and I am positive its A
(f+g)(x)=f(x)+g(x)
=(-3x-5)+(4x-2)
= -3x-5+4x-2. collect like term
= -3x+4x-5-2
= x-7. the final answer
4004
The number of combinations of choosing r objects from a group of n is nCr.
So the number of ways to get 7, 8, 9, or 10 heads from 13 coin tosses is:
₁₃C₇ + ₁₃C₈ + ₁₃C₉ + ₁₃C₁₀
= 1716 + 1287 + 715 + 286
= 4004
