What is the 9the term of the sequence?
jeka57 [31]

Answer

A. 196,608

Step-by-step explanation:

-12/3 = -4

48 / -12 = -4  and -192 / 48 = -4

This is a geometric sequence with common ratio -4.

an = a1 r^(n -1)  so:-

9th term (a9)  =   3*(-4)^(9-1)

= 196,608

The function f(x) is shown in this graph.
Alexus [3.1K]

Answer:

A maybe?

Step-by-step explanation:

by looking at the graph you can see there are two points with one being at (0, 3) (given) and the other being at (1, 1) (by looking at the graph). You can use the slope formula (y2 - y1) / (x2 - x1) which gives you the slope.

Plug Values In:

(1-3) / (1-0) = -2/1 = -2

slope of f(x) = -2

slope of g(x) = -7 (slope-intercept form y=mx+b where m is the slope and b is the y-intercept)

I'm honestly not quite sure what it means by greater than since technically the slope of f(x) is greater than the slope of g(x) but does it mean how much it's changing by in which case the sign doesn't matter. Although I'm just going to assume it purely means the value in which case A is true.
