Answer:
a7=a3 ^n-1
Step-by-step explanation:
:) Good day
Instead of plugging in
and
right away, notice that
![m^2-2mn+n^2=(m-n)^2](https://tex.z-dn.net/?f=m%5E2-2mn%2Bn%5E2%3D%28m-n%29%5E2)
and now evaluating this expression at the two given values is easier, if only a little:
![((-2)-4)^2=(-6)^2=(-1)^2\times6^2=1\times36=36](https://tex.z-dn.net/?f=%28%28-2%29-4%29%5E2%3D%28-6%29%5E2%3D%28-1%29%5E2%5Ctimes6%5E2%3D1%5Ctimes36%3D36)
If the amount of members are y, then the total number of people who attend is x+y=19. In addition 11*y (since it costs 11 dollars per member)+13*x=209. Subtracting x from both sides in the first equation, we get y=19-x. Plugging that into the second equation, we get (19-x)*11+13*x=209. Multiplying it out, we get 201-11x+13x=209. Subtracting 201 from both sides, we get 2x=8 and by dividing both sides by 2 we get x=4
The sentences that are true are..:
Two sides have the same length
The third angle measures 70°
It is an acute triangle.
i know that because eat triangle is 180°, so if we subtract 40° and 70° from 180°, we get 70°, meaning the three angles in the triangle are 40°, 70°, and 70°. Because all of the angles are under 90°, we know that it is an acute triangle.
Answer:
1.
E(down) / Odd(Across) H T
H (1,-1) (-1,1)
T (-1,1) (1,-1)
2. Even doesn't have a dominant strategy as both the strategies are providing equal payoffs for pure strategy.
