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 ............ }

M is the midpoint of AB and C is the midpoint of AM . Let the coordinate of A = 7y and the coordinate of B = 3x. Find the coordi

xz_007 [3.2K]

Answer:

The answer is below

Step-by-step explanation:

The coordinate of the midpoint of a line is gotten by adding the values of the two end points and then dividing the result by 2.

Given that M is the midpoint of AB, A = 7y and B = 3x, hence the coordinate of point M is given as:

M = (A + B)/2 = (7y + 3x)/2

Also, C is the midpoint of AM, hence the coordinates of point C is given as:

$C=\frac{A+M}{2}\\ \\C=\frac{7y+\frac{3x+7y}{2} }{2}\\ \\C=\frac{\frac{14y+3x+7y}{2} }{2}\\ \\C=\frac{21y+3x }{4}$

Hence the coordinates for point C is $C=\frac{21y+3x }{4}$
