Enter the explicit rule for the geometric sequence. 120, 40, 40/3, 40/9, 40/27,  i know the first part would be but i dont know what would be put in the middle of the parenthesis so if anyone could that would be awesome ty! an= 120( )^n-1

Step-by-step explanation:

The given geometric sequence is 120, 40, 40/3, 40/9.........n terms.

As we know nth term of a geometric sequence is represented as

Here a(n) = nth term

a = first term

r = common ratio

n = number of terms

In this sequence a = 120

r = second term/first term = 40/120 = 1/3

Therefore the sequence can be represented as

Explicit rule of the geometric sequence is

i dont know

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
