Answer:
Suppose that A is the set of sophomores at your school and B is the set of students in discrete mathematics at your school.
a) It is the intersection A ∩ B
b) This is the difference A − B.
c) It is the union A ∪ B.
--- ---
d) It can be shown as A ∪ B. (bar over A and B both)
Answer:
c = 3√5 ≈ 6.708
Step-by-step explanation:
Use the Pythagorean Theorem because this is a right triangle.
a^2 + b^2 = c^2
3^2 + 6^2 = c^2
9 + 36 = c^2
45 = c^2
√45 = c
<u>c = 3√5 ≈ 6.708</u>
Answer:
B
Step-by-step explanation:
Answer:
DE
Step-by-step explanation:
(5b)(-3a)
= (5*(-3))(b*a) (combine like terms)
= -15ab
The final answer is -15ab~
