Ok but u forgot to add the picture
hay here is your answer and hope it's clear :) and if it's not clear [ download photo math] it maybe helpful for you ;)
The answers are A and E because .026 x 100 = 2.6 and 2.60 / 100 = .026
Answer:
a) h∧¬r→s
b) r→¬s
c) s→h
c) s→¬r
Step-by-step explanation:
a) The sufficient condition for "I will go swimming" is "it's hot and not raining" . With your variables, the sufficient condition for s is h∧¬r. Then, if h∧¬r is true, s will be true, which means that h∧¬r implies s.
b) This means that the only thing that would stop you from go swimming is that its raining. Then, if it rains, you won't go swimming, that is, r implies ¬s.
c) It is necessary (it must happen) that it is hot for you to go swimming. Then, it you are swimming, it must be hot (otherwise you wouldn't be swimming), hence s implies h
d) Just as in c), if you go swimming, it must not be raining. Then s implies not r.
Some final comments. Suppose you have the implication p→q. Then, it is equivalent to say:
- p is sufficient for q (If p then q)
- q is necessary for p (p only if q)
The correct answer would be true.
To verify that triangle WXY is a right triangle, use the Pythagorean theorem or
a^2+b^2=c^2 where a and b are the two shorter legs and c is the hypotenuse.
If a^2+b^2 is equal to c^2, then it is a right triangle. If a^2+b^2 is greater that c^2, then the triangle is acute and if a^2+b^2 is less than c^2, then the triangle is obtuse.
When you plug in the values into the theorem, you should get:

^2+

^2 =

^2
This would simplify to 17+17=34 which simplifies to 34=34.
Because a^2+b^2 equals c^2, you can conclude that triangle WXY is a right triangle.
