Answer:
Step-by-step explanation:
WE are given that
. Then, to now the first for terms, we must replace n by 1,2,3,4 respectively. Then
![a_1 = \frac{(-1)^2}{5(1)-4} = \frac{1}{1}= 1](https://tex.z-dn.net/?f=a_1%20%3D%20%5Cfrac%7B%28-1%29%5E2%7D%7B5%281%29-4%7D%20%3D%20%5Cfrac%7B1%7D%7B1%7D%3D%201%20)
![a_2 = \frac{(-1)^3}{5(2)-4} = \frac{-1}{6}](https://tex.z-dn.net/?f=a_2%20%3D%20%5Cfrac%7B%28-1%29%5E3%7D%7B5%282%29-4%7D%20%3D%20%5Cfrac%7B-1%7D%7B6%7D%20)
![a_3 = \frac{(-1)^4}{5(3)-4} = \frac{1}{11}= 1](https://tex.z-dn.net/?f=a_3%20%3D%20%5Cfrac%7B%28-1%29%5E4%7D%7B5%283%29-4%7D%20%3D%20%5Cfrac%7B1%7D%7B11%7D%3D%201%20)
![a_4 = \frac{(-1)^5}{5(4)-4} = \frac{-1}{16}= 1](https://tex.z-dn.net/?f=a_4%20%3D%20%5Cfrac%7B%28-1%29%5E5%7D%7B5%284%29-4%7D%20%3D%20%5Cfrac%7B-1%7D%7B16%7D%3D%201%20)
Note that as n increase,
gets closer to 0. So, the limit of this sequence is 0.
Answer:
C. 70°
Step-by-step explanation:
The inscribed angle marked 15° intercepts an arc that is double that measure, so the intercepted arc on the right is 2×15° = 30°.
The external angle marked 20° is half the difference of the intercepted arcs, so is ...
20° = (1/2)(x - 30°)
40° = x - 30° . . . . . . multiply by 2
70° = x . . . . . . . . . . . add 30°
The value of x is 70°.
