3(-7)² - 8(-7)³ + 4(-2)²
becomes:

-147 - 2744 + 16 = 2907

but if you do the problem the original way it's written, it equals -2875.

-147 - 2744 + 16 = -2875

So why do I have to do it this way to get the correct answer?

147 + 2744 + 16 = 2907

What happened to 147 being negative? How can I tell when to add the absolute value? How do I know when to switch adding to subtracting or vice versa?

The spring of a spring gun has force constant k = 400 N/m and negligible mass. The spring is compressed 6.00 cm and a ball with mass 0.0300 kg is placed in the horizontal barrel against the compressed spring. The spring is then released, and the ball is propelled out the barrel of the gun. The barrel is 6.00 cm long, so the ball leaves the barrel at the same point that it loses contact with the spring. The gun is held so the barrel is horizontal.

(a) Calculate the speed with which the ball leaves the barrel if you can ignore friction.

(b) Calculate the speed of the ball as it leaves the barrel if a constant resisting force of 6.00 N acts on the ball as it moves along the barrel

(c) For the situation in part (b), at what position along the barrel does the ball have the greatest speed? (In this case, the maximum speed does not occur at the end of the barrel.)

(d) What is that greatest speed?

I am talking about bipolar mood disorder. I have been diagnosed with bipolar mood disorder for 2 months now. Medicines are greatly working. I am taking Lamictal 50mg and Seroquel 25mg. Adepsir or my anti-depressant was taken already. It would be my first day today without anti-depressant. Well, I feel good! I was in my depression state 2 months ago. My doctor told me this morning that I need not take anti-depressant anymore but I have to maintain Seroquel and Lamictal. For those who have been long in this illness, I would like to ask you on how you could possibly detect that you are in your normal state? For me, as long as I feel happy and people around me seem so important to me and when I value money and relationship then I should say , I am in my normal state.. Please give me your experiences so that I will also be guided on this progress of recovery. I believe we can do it as we share all the things that we have experienced. Remember, there is nothing impossible only if you believe

A thin, uniform 12.0-kg bar that is 2.00 m long rotates uniformly about a pivot at one end, making 5.00 complete revolutions every 3.00 seconds

What is the kinetic energy of this bar? (Hint: Different points in the bar have different speeds. Break the bar up into infinitesimal segments of mass dm and integrate to add up the kinetic energy of all these segments.)

What do you think of this statement?

"If it is sunny or if I have no work to do, then I am happy. I am happy and it is sunny. Therefore I have no work to do."

Let me define each of these statements:
Let p: "It is sunny"
Let q: "I have work to do"
Let r: "I am happy"

My answer is:
{ [ (p V ~q) => r ] Λ (r Λ p) } => ~q
Is my answer right? My teacher told me that it is right, but I have doubts in it. Can this statement "IF it is sunny or IF I have no work to do, then I am happy." be said as: (p => r) Λ (~q => r)? I tried comparing their results using a TRUTH TABLE but the outputs are not the same.

For those who are willing to help and did not encounter LOGICAL CONNECTIVES: The symbol ' V ' means OR. The symbol ' Λ ' means AND. The symbol ' => ' means imply (conditional purposes only)
