What is the common ratio of the sequence -2, 6, -18, 54
dsp73

The common ratio of a geometric sequence is the ratio of any term to the one before it. Here, you can find it by

... 6/-2 = -3

or, if you prefer the minus sign in the numerator, ...

... -18/6 = -3

or the ratio of any other sequential terms.

DENIUS [597]

<u>Answer:</u>


The right graph is the first one (figure attached).

Note that in a Speed vs Time graph, the constant speed is represented by a line with slope=0 <u>(for example, segment 1)</u>, when the speed increases the slope is positive <u>(for example, segment 2)</u> and when the speed decreases the slope is negative <u>(for example, segment 4).</u>

Now, if we want to prove this, let’s read again the problem, <u>dividing each section of the path Marc drove to his work</u> (see figure attached):

1. He slowly pulls out of his driveway at a <u>constant speed </u>

2. and then his <u>speed increases</u> steadily

3. until he reaches the speed limit. He uses cruise control to drive the speed limit  <u>(he drives at constant speed)</u>

4. until he comes upon some traffic (usually if you find some traffic you have to <u>derease your spped</u>)

5. He then slows down to a new <u>constant speed</u>.

6. When he gets near his office, his <u>speed steadily decreases</u> until he comes to a stop right in front of his office building  <u>(at this point the speed is zero)</u>

1 - 1 = 0:

7×0 + 8
