Help please! First three terms of a sequence is shown below. Determine if the sequence is geometric. If so, state the common ratio.

30, 10, 103, ...

a. The sequence is geometric, and the common ratio is 13.

b. The sequence is geometric, and the common ratio is 3.

c. The sequence is geometric, and the common ratio is -20.

d. The sequence is not geometric.

Step-by-step explanation:

The common ratio is a constant found by dividing any term by the previous term.

10/30=1/3

103/10=10.3

Since those fractions are not equal this is NOT a geometric sequence.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
