Given: AB ⊥ l, B ∈ l, M ∈ AB , AM = 7 in, AB = 15 in. Find the distance between point M and line l.
elixir [45]

AB ⊥ l, B ∈ l, M ∈ AB , AM = 7 in, AB = 15 in.

Here AB is a line segment which is perpendicular to line I.

Point B lies on line I,and Point B lies on line segment AB.

⇒AB=15 [Given]

⇒AM+MB=15

⇒AM=7[given]

⇒7+MB=15

⇒MB=15-7

⇒MB=8in

So,the length of line segment MB is 8 in.

The same thing is depicted in the diagram.

Which of the following are valid (necessarily true) sentences? a. (∃x x = x) ⇒ (∀ y ∃z y = z). b. ∀ x P(x) ∨ ¬P(x). c. ∀ x Smart
Phantasy [73]

Answer:

b; ∀x   P(x) ∨ ¬P(x)

Step-by-step explanation:

Suppose that we have a proposition p

Such that p can be true or false.

We can define the negation of p as:

¬p

Such that, if p is false, then ¬p is true

if p is true, then ¬p is false.

Also remember that a proposition like:

p ∨ q

is true when, at least one, p or q, is true.

Then if we write:

p ∨ ¬p

Always one of these will be true (and the other false)

Then the statement is true.

And if the statement depends on some variable, then we will have that:

p(x) ∨ ¬p(x)

is true for all the allowed values of x.

from this, we can conclude that the statement that is always true is:

b; ∀x   P(x) ∨ ¬P(x)

Where here we have:

For all the values of x,   P(x)  ∨ ¬P(x)
