Check the picture below.
since chords NQ and MP cross the center of the circle at R, that means that those two chords are diametrical chords and the angles made by both are vertical angles and thus twin angles, namely both are 18° as you see in the picture, so the angle NMP in magenta is really 162° + 18° + 18° = 198°, and we know the radius NR is 8.
Answer:
3) ,
Step-by-step explanation:
Given that the explicit rule for a sequence is .
Now we need to find about what is the recursive rule for the sequence and match with the given choices to find the correct choice.
1) ,
2) ,
3) ,
4) ,
Plug n=1 into given formula to get first term
base of the exponent part is (-2) so that means we need to multiply -2 to the previous term to get nth term
Hence correct choice is: 3) ,
