Answer:
D
Explanation:
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]

why are boys/men tough on the outside but sensitive on the inside need help
Answer:
People who act tough thrive on feeling like they have power over other people. They want to be perceived as being "in control," and they often micromanage others or make unreasonable demands. Mentally strong people, however, are interested in controlling themselves rather than the people around them.
Explanation:

Answer:
To protect their sensitive masculinity.
Explanation:
Males act like that so they seem masculine because males are considered 'tough' and 'strong' emotionally. Females are usually considered 'weak' emotionally, and this develops a sense of femininity. This is not true because both genders have sensitivity, it's just because we have adapted to this society and its stereotypes. Everyone is different! Okay sorry for the speech...

Answer:
eat more meals at restaurants
Answer:
eat more meals at restaurants
Explanation:
The First Choice: exercise with friends or join a team it a great improvement
The Second Choice: eat snacks from a smaller sized bad is a pretty great improvement at wells but a little less beneficial compared to the first.
The Third Choice: Increasing exercise frequently will also provide a more positive impact as long as it isn't to much. so it might be as important as the first choice.
The Fourth Choice: eating more meals at restaurants. Eating out is something that is not to be over indulged in because it is proven cooking at home is better for your health (and saving money). If Jordan eats more meals at restaurants, her overall fitness is likely to go down. This makes it the answer because it would least improve her fitness.

Help please? “Explain the process of how we can have a runny yolk when we cook a fried egg.” It needs to be a detailed answer so my mind is blank please help :))
All you’ll need for this recipe is a quality cooking pan (we prefer cast iron over stainless steel or non-stick), a bit of oil to grease the pan, good quality eggs (we prefer organic pasture-raised), and seasonings of choice (we prefer salt and pepper).
Cracking an egg in a skillet for our tutorial on How to Cook and Egg Perfectly Every Time.
Once your pan is hot over medium heat, add a bit of oil, swirl to coat, then crack your eggs in, being careful not to break the yolks. Then season with a pinch each salt and pepper (or desired seasonings) and cook for a few minutes uncovered (this allows the whites to start cooking without the yolks getting cooked). Around the 3-minute mark, just before the whites are cooked, cover with a lid. This will allow the whites to firm up without overcooking the yolks.Ah, perfect eggs every time. There you have it!
