Sin2alpha+cos2alpha-cos6alpha/sin4alpha+2sin²alpha-1<br><br> if alpha is -135°​
balandron [24]

Answer:

=  \frac{\sin(2 \alpha )  +  \cos(2 \alpha )  -  \cos(6 \alpha ) }{ \sin(4 \alpha )  + 2 { \sin }^{2}  \alpha  - 1}  \\  =  \frac{ \sin( - 270) +  \cos( - 270)  -  \cos( - 810)  }{ \sin( - 540)  + 2 { \sin }^{2}( - 135) - 1 }  \\  =  \frac{1}{ - 2}  \\  =  - 0.5

A presidential candidate plans to begin her campaign by visiting the capitals in 44 of 5050 states. what is the probability that
defon
Part A:

Given that <span>A presidential candidate plans to begin her campaign by visiting the capitals in 4 of 50 states.

The number of ways of selecting the route of 4 specific capitals is given by

^{50}P_4= \frac{50!}{(50-4)!} =  \frac{50!}{46!} =50\times49\times48\times47=5,527,200

Therefore, the probability that she selects the route of four specific​ capitals is \frac{1}{5,527,200}



Part B:
</span>
<span>The number of ways of selecting the route of 4 specific capitals is 5,527,200.

Since </span><span>the number of ways of selecting the route of 4 specific capitals is too large it is not practical to list all of the different possible routes in order to select the one that is​ best.

Therefore, "</span><span>No, it is not practical to list all of the different possible routes because the number of possible permutations is very large."</span>
