1) Demuestre Si la proposición ¬ ( p Ʌ ¬ q Ʌ ¬ r) es falsa, entonces la proposición

p → ( q Ʌ r ) es:

a) Verdadera b) Falsa

2) Identifique cuál de las siguientes formas proposicionales NO es tautológica.

a) (p v q ) → (¬p →q)

b) [ (p → r ) Ʌ ( q → r ) ] → [ ( p v q ) → r ]

c) [ ( p v q ) Ʌ ¬p ] → q

d) [ ( ¬q → ¬p ) ] → ¬q

e) [(p → q ) Ʌ ( q → r )] → (p → r )

AYUDAAA, HELP MI PLS.

Muchas gracias de antemano!

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
