Now,

Sum of a finite geometric series=a(r^(n) -1)/(r -1)
or

Answer:
yes
Step-by-step explanation:
60 - 0.1(60) = 54
60 - 6 = 54
54 = 54
Answer:
y = 189.8
Step-by-step explanation:
Apply trigonometric function to find y.
Reference angle (θ) = 50°
Adjacent side = 122
Hypotenuse = y
Apply CAH, since the Hypotenuse and the Adjacent are involved.
Thus:
Cos θ = Adj/Hypo
Plug in the values
Cos 50° = 122/y
y*Cos 50° = 122
y = 122/cos 50°
y = 189.8 (beater tenth)
