Suppose that P(n) is a propositional function. Determine for which improper subset of the domain of n the statement P(n) must be

Alinara [238K]

Answer:

a) P(n) is true for all 'n' in the set ; { 0,2,4,6,8 ….. }

b) P(n) is true for all 'n' in the set ; { 0,1,2,3,4,5 ............ }

Step-by-step explanation:

a) As P(0) is true

we will assume that

P(2) is true
P(4) is true
P(6) is true

this simply means that ; P(n) is true for all 'n' in the set

{ 0,2,4,6,8 ….. }

b) since P(0) and P(1) are true

we will assume that

P( 0+2 ) = P(2) is true

also P(1) and P(2) are true

we will assume that

P(1+2) = P(3) is true

Also from the previous answers it can be seen that P(2) + P(3) is true

we will assume

P(2+2) = P(4) is true

This simply means that P(n) is true for all 'n' in the set

{ 0,1,2,3,4,5 ............ }

It takes Dave's dogs about 20 days to finish a 50-pound bag bag of dog food. which is the best estimate of number of pounds of d

Fynjy0 [20]

The correct answer is C) 900

To begin with, you need to divide the number of days in a year with the number of dogs. When you do this, you multiply it by 50 to get the final answer. In this case, it would be 365 / 20 which when multiplied by 50 gives the number of C) 900 since it's "about" 20 days.

A model car is 5 inches long. The actual length of the car is 15 feet . What is the scale factor of the model car?

Elodia [21]

Answer:

1 : 36

Step-by-step explanation:

To obtain the scale factor, the dimensions must be in the same units.

Using the conversion

1 foot = 12 inches, then

15 feet = 15 × 12 = 180 inches, thus

scale factor = 5 : 180 ← divide both parts by 5
