Good evening
Answer:
<h2>130</h2><h2 />
Step-by-step explanation:
let L represent the length of the hypotenuse :
Since we are in a right triangle case then the Pyth theorem is a valid choice to solve the problem :
the Pythagoren theorem states that :
L² = 50^2+120^2
then
L² = 16 900
then
L = √(16 900)
=130

the answer is in the image above
Answer:
~p -> ~q
Step-by-step explanation:
A conditional statement in logic may be symbolized by the alphabets, p and q, It always contains an if - then statement.
There is always a logical connector in the statement with the symbol ->.
A conditional statement is false if the hypothesis is true and the conclusion is false.
The statement in the answer above reads in word; "if not p then not q".
-2 = - x + x^2 -4 => x^2 - x - 4 + 2 = 0
x^2 - x - 2 = 0
a is the coefficient of x^2 => a = 1
b is the coefficient of x => b = - 1
c is the constant term => c = - 2
quadratic equation: [- b +/- √(b^2 - 4ac) ] / 2a =
= { 1 +/- √[ (-1)^2 - 4(1)(-2)] } / (2(1) = { 1 +/- √ (1 + 8) } / 2 = {1 +/- √9} / 2 =
= { 1 +/- 3} / 2
I think this would be 4≥X<span>>-8
