Answer:
179.159
Step-by-step explanation:
Given the sequence :
50, 60, 72,..
The sequence given is a geometric sequence :
For a geometric sequence ;
ar^(n - 1)
a = first term
r = a2 / a1 = 60 / 50 = 1.2
The 8th term ; n =8
a8 = ar^(n - 1)
a8 = 50*1.2^(8 - 1)
a8 = 50*1.2^7
a8 = 50*3.5831808
a8 = 179.15904
a8 = 179.159 (nearest thousandth )

Answer:
13. -2
14. 0
15. 2
16. 0
Step-by-step explanation:
Since the function is originally f(x), you go to wherever the x value is and see what the y value is.
So...
f(2) means go to x = 2 and see that y = -2
2n^2-20=0
2n^2=20
n^2=20÷2
n^2=10
n=radical 10
