Write the nth term of the following sequence in terms of the first term of the sequence.

10, 20, 40, . . .

10, 20, 40, 80, 160, 320, 640, 1280

Step-by-step explanation:

The number doubles each time

The answer is 10(2)^(n-1).

Step-by-step explanation: I hope this helps you. (I'm on Odyssey.)

(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
