Answer:
Logic with the use of Truth Table
Step-by-step explanation: a) Oleg is a math major= P; Oleg is a economic major=Q; Oleg is required to take math 362=R; Oleg is not required to take 362=←R
b)i) Oleg is a math major or Oleg is an economic major:
P║ Q ║ P∨Q
T T T
T F T
F T T
F F F
ii) Oleg is a math major, then Oleg is required to take Math 362:
P║ R ║ P∧ R
T T T
T F F
F T F
F F F
iii) Oleg is an economic major or Oleg is not required to take Math 362:
Q║ ←R ║ Q ∨ ←R
T T T
T F T
F T T
F F F
c) It is valid because Oleg can only take Math 362 since Oleg is a math major, therefore, it follows that, R ∧ ( P ∨ Q) is valid.

Answer:
C: 11.5 cm, 4.2 cm, 7.6 cm
Step-by-step explanation:
In order for the lengths to form a triangle, the sum of the shortest two must exceed the longest.
A. 5.4 +5.4 = 10.8 < 12.6
B. 1.3 +5.9 = 7.2
C. 4.2 +7.6 = 11.8 > 11.5 . . . . will make a triangle
D. 3.1 +6.6 = 9.7 < 10.4
Well think about it. 70 mph then how long does it take to get to 70miles. An hour.. Just make it specific
