Which details from the text support the central idea of
the passage? Check all that apply.
Stress. It's a part of life, no matter who you are, where
you live, or how old you are. Stress has a nasty reputation
for being something people should avoid at all cost
because of how-you guessed it-stressful it is. However,
stress is not necessarily negative at all. People often use it
as the springboard for achieving more. Many find that
stress motivates, energizes, and inspires them to work
harder or faster. Unfortunately, stress frequently ends up
being an unpleasant event for people.

Answer:
"stress is not necessarily negative"

Explanation:
The central idea of the passage is that, despite its bad reputation, stress can have both positive and negative effects.
The parts of the text that sustain that idea claim that, although it can be disturbing, stress can also lend impetus to greater achievements, because it stimulates action, as well as it provides higher energy and inspiration.
Stress is a situation where the person is mentally exerted because of some emotional, physical or social concerns. The person experiencing stress is not able to deal with the rational or the emotional state he is in.

Stress can be helpful or bad. Good stress inspires and motivates the person to collect and concentrate his energy to overcome his issue.Bad stress exhausts the person and leaves the person tensed. It can be harmful to health.Stress can be positively shaped into a bundle of energy to achieve your goal and to end the unpleasant feeling of worry.Therefore, stress can be positive and can act as a motivation to channelize your energy.

1. How would you help a friend who is dating someone physically abuse? Explain your worries, and list resources that could be helpful.
Answer:
I could:
Give my friend access to emergency help. S**cide hotlines, physical, and domestic abuse hotlines are all good options. Just make sure your friend has proper access to them.Discuss the risks and form an action plan with my friend. I could get together with my friend in a private and safe place. Then, I could discuss with them why and how the abusive relationship should stop. I could figure out a safe way out, and help them every step of the way.Explanation:
My worries:
I would be worried about them getting in an emergency where they were unsafe, and couldn't get help from me for some reason. They could instead use the resources I have given them, and receive assistance.I would also be worried about making sure my friend knows exactly what to do to get out of the abusive relationship. They might not realize the risks of staying with their abusive partner, and get into unsafe situations, too. We could both discuss the risks and form the action plan, at somewhere safe. That way, my friend realizes what they're in, and how they can get out of it.I hope this helps!

prove sinA*cos2A=1/4sin4A*secA
Answer:
The prove is below
Explanation:
From trigonometric identities:
[tex]cos2A=cos(A+A)=cos^2A-sin^2A\\sin2A=sin(A+A)=2sinAcosA\\sin4A=sin(2A+2A)=2sin2Acos2A=2(2sinAcosA)(cos^2A-sin^2A)=4sinAcos^3A-4cosAsin^3A\\secA=\frac{1}{cosA}[/tex]
Therefore:
[tex]\frac{1}{4}sin4AsecA = \frac{1}{4}( 4sinAcos^3A-4cosAsin^3A)\frac{1}{cosA}\\= sinAcos^3A-cosAsin^3A(\frac{1}{cosA} )\\=sinAcos^2-sin^3A\\=sinA(cos^2A-sin^2A)\\But\ cos^2A-sin^2A=cos2A\\Therefore:sinA(cos^2A-sin^2A)=sinAcos2A\\\frac{1}{4}sin^4Acos2A=sinAcos2A[/tex]
