Answer:
S₃ = 37
Step-by-step explanation:
given a₁ = 16 and r =
, then
a₂ = a₁ ×
= 16 ×
= 12
a₃ = a₂ ×
= 12 ×
= 9
then
S₃ = a₁ + a₂ + a₃ = 16 + 12 + 9 = 37
Answer:
z ≥ -10
Step-by-step explanation:
When the circle is filled it means the direction its going (less than or greater than) or equal to in this case the line is going farther than -10 so its greater than or equal to -10. Z would be your variable so its z ≥ -10
Answer:
(a) 85,602,300
(b) 352,621,800
Step-by-step explanation:

(a) In 1998, <em>x</em> = 1998 - 1985 = 13

The number of subscribers in 1998 = 85602.3 × 1000 = 85,602,300
(b) In 2009, <em>x</em> = 2009 - 1985 = 24

The expected number of subscribers in 2009 = 352621.8 × 1000 = 352,621,800
