A circus acrobat is shot out of a cannon. The equation for the acrobat's pathway can be modeled by h= -16t^2+25. How long will i
Alex_Xolod [135]
For this we almost have the following equation:
 h = -16t ^ 2 + 25&#10;
 We must match the equation to zero:
 -16t ^ 2 + 25 = 0&#10;
 From here, we clear the value of t.
 We have then:
 16t ^ 2 = 25&#10;&#10;t ^ 2 = 25/16
 We discard the negative root because we are looking for time:
 t =  \sqrt{ \frac{25}{16} } &#10;&#10;
 t =  \frac{5}{4}
 Answer:
 
it will take him to reach the ground about:
 
t = \frac{5}{4} seconds

In a certain pond, 50 fish were caught, tagged, and returned to the pond. A few days later, 50 fish were caught again, of which
mario62 [17]

2 out of 50 were tagged.

Divide 2 by 50:

2/50 = 0.4 ( This is 4% of the fish were tagged).

Now divide the number of fish caught by the percentage that were tagged:

50 / 0.04 = 1250

The number of fish in the pond is C. 1250

Prove the identity sin4x=2sin2xcos2x
Musya8 [376]
There is a trig identity called the sum of 2 angles for sin its<span>
sin(a+b)=sin(a)cos(b)+cos(a)(sin(b)
</span>
You will need to use it. So in your question split the 4x in 2 equal parts 2x and 2x
 <span>
</span><span>sin(4x)=sin(2x+2x)

</span>Now using the expansion above you will get

<span>sin(2x+2x)=sin(2x)×cos(2x)+cos(2x)×sin(2x)

</span>And it will simplify to 

<span><span>2sin(2x)cos(2x)

I hope this helps you! Good luck :)</span></span>
