If the sides of the triangle have lengths of: 2, 1, and 2√3
Then, the triangle is a
c. neither a 45-45-90 triangle nor a 30-60-90 triangle.
Looking at the lengths, if the triangle is a right triangle
2 and 1 must be the measure of the legs
2√3, the measure of the hypotenuse
If we use the Pythagorean theorem,
2^2 + 1^2 = (2√3)^2
5 = 12 (not correct)
Therefore, the triangle is not a right trangle
The explicit formula of the sequence is given by a_n = -4n(n-1).
We have to find the first five terms of the sequence.
The first term:
![\begin{gathered} a_1=-4\times(1)(1-1) \\ =-4(0) \\ =0 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20a_1%3D-4%5Ctimes%281%29%281-1%29%20%5C%5C%20%3D-4%280%29%20%5C%5C%20%3D0%20%5Cend%7Bgathered%7D)
The second term:
![\begin{gathered} a_2=-4(2)(2-1) \\ =-8(1) \\ =-8 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20a_2%3D-4%282%29%282-1%29%20%5C%5C%20%3D-8%281%29%20%5C%5C%20%3D-8%20%5Cend%7Bgathered%7D)
The third sum:
![\begin{gathered} a_3=-4(3)(3-1) \\ =-12(2) \\ =-24 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20a_3%3D-4%283%29%283-1%29%20%5C%5C%20%3D-12%282%29%20%5C%5C%20%3D-24%20%5Cend%7Bgathered%7D)
The fourth term:
![\begin{gathered} a_4=-4(4)(4-1) \\ =-16(3) \\ =-48 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20a_4%3D-4%284%29%284-1%29%20%5C%5C%20%3D-16%283%29%20%5C%5C%20%3D-48%20%5Cend%7Bgathered%7D)
The fifth term:
![\begin{gathered} a_5=-4(5)(5-1) \\ =-20(4) \\ =-80 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20a_5%3D-4%285%29%285-1%29%20%5C%5C%20%3D-20%284%29%20%5C%5C%20%3D-80%20%5Cend%7Bgathered%7D)
Thus, option D is correct.
