<span>The absolute value is 9.8, (example): if it was -3 (negative 3) then the absolute value would be just 3 (or positive 3). The absolute value is always positive.
Hope this helped! :)</span>
Hello there.
In this problem, we can use our intuition of logic, but I will show a proof of the result in a truth table later. Then, let's get started!
Given:
→ Amelia finishes the homework (sentence H, can be True or False)
→ Amelia goes to the park (P, true or false)
Then, we have: If H, then P. Logically:
H ⇒ P
Then we can think: <em>everytime</em> she does the homework, she goes to the park. Therefore, if she did not go to the park, she will not have finished the homework (It is an equivalent sentence).
<em>Alternative 1</em>.
==========
Now, let's prove that (H ⇒P) is equivalent to (¬P ⇒ ¬H), via the truth table:
H P ¬H ¬P (H ⇒ P) (¬P ⇒ ¬H)
T T F F T T
T F F T F F
F T T F T T
F F T T T T
As we can see, the results are identical, therefore, the sentences are indeed equivalent.
I hope it hepls :)
Answer:
(did you forget the picture?) if those numbers are the lengths of the prism just multiply them all.
multiply them to get 60.9
