Looking at the permutation formula, we have n!/(n-r)!. n is the number of objects to select from and r is how many are to be picked at once. And 1 means multiply from there down basically. 5!/(5-4)!= 5*4*3*2*1/1. 5 times 4 is 20 times 3 is 60 times 2 is 120 times 1 is 1 so 120/1 is 120. There are 120 total combinations to be made from P, Q, R, S and T.
9 - 22 is -13 then add 12 yards equals -1 so they just lost one years from where they started so the answer is -1

Step-by-step explanation:
Sin2α = 2SinαCosα.
Cos2α = (Cosα)^2 - (Sinα)^2.
Sin4α can be written as Sin2(2α).
Similarly Cos4α can be written as Cos2(2α).
It is given that tanα=3.
Sinα(Sinα) = 
[
], the values either be both positive or both negative, as the value of tanα is positive only on first and third quadrant.
Sin4α = 
.
Cos4α =
