If p is true and ~ q is false, then p -> ~ q is always, sometimes, never false.
If p is true and q is true, then ~ p -> ~ q is always, sometimes, never true.
If p -> q is true and q is true, then p always, sometimes, never is
Answers
1. If p is true and q is false, the p -> q is never true.
2. When p is false and q is true, then p or q is always true.
3. If p is true and ~ q is false, then p -> ~ q is never false.
4. If p is true and q is true, then ~ p -> ~ q is always true.
5. If p -> q is true and q is true, then p is always true.
Further Explanation:
The logic gates are used here.
Here, the symbol -> is for implication. Implication p-> q means that if p is true then q must be true.
So let us look at all the questions one by one.
1. If p is true and q is false, the p -> q is always, sometimes, never true.
p -> q
true -> false
The true should imply true so the given statement will never be true.
2. When p is false and q is true, then p or q is always, sometimes, never true.
false or true
We know that in or gate even if one input is true, the whole output is true. So this statement will be always true given p is false and q is true.
3. If p is true and ~ q is false, then p -> ~ q is always, sometimes, never false.
This translates to:
true -> true
So it will never be false.
4. If p is true and q is true, then ~ p -> ~ q is always, sometimes, never true.
This translates to:
false -> false
This will always be true.
5. If p -> q is true and q is true, then p is always, sometimes, never true.
If p->q is true and q is true then p will always be true. "Implies to" states that in p->q, in order for q to be true p has to be true. So p will always be true.

so
-17 +/- (17^2-4(2)(-21))^1/2

-17 +/- (457)^1/2

so the zeros are roughly 1.094 and -9.594
What is the elevation of the bottom of
the canyon?
Answers
Answer:
145 feet.
Step-by-step explanation:
Given that:
An underwater canyon begins at depth = 40 ft
Depth of canyon = 105 ft
To find:
The elevation of the bottom of the canyon = ?
Solution:
Kindly refer to the image attached for the given dimensions.
A is the sea level.
B is the point at which the canyon starts and
C is the bottom of the canyon.
As per question statement, we are given that:
AB = 40 feet
BC = 105 feet
And we have to find the distance AC = ?
It is clearly observable that:
So, the elevation of the bottom of the canyon is 145 ft.

25 + 25 = (5*1.414...)^2 =
50 =(7.0710678119) ^2
and 7.0710678119^2 = 50 so it is a right triangle.
To be specific, it is an isosceles right triangle.
