What is the common ratio between successive terms in the sequence 2, 4, 8, -16, 32, -64

Mathematics
1 answer:
Simora [160]3 years ago
8 0

Answer:

  this sequence has no common ratio

Step-by-step explanation:

The ratios of successive terms are ...

  4/2 = 2

  8/4 = 2

  -16/8 = -2

  32/-16 = -2

  -64/32 = -2

2 is not the same as -2, so this sequence has no common ratio.

___

The sequence 2, -4, 8, -16, 32, -64 will have a common ratio of -2 using the same method to find it.

Jasmine reduced the size of a triangle to a height of 4 in. What is the new width if it was originally 12 in wide and 16 in tall
cupoosta [38]

Answer:

The new width is 3 in.

Step-by-step explanation:

We can use the ratio of w/h, the origal width and height should have the same ratio as the new width and height.

<u>12 </u>= <u>x</u>

16    4

Then solve for x:

x = 4 (12/16)

x = 3

To check:

12/16 = 3/4

3/4 = 3/4

Choose the equation that satisfies the data in the table.<br> HELP!!!!
harina [27]

The equation of the line represented by the table in slope intercept form is; y = ²/₁₅x + 2

<h3>How to solve equation in slope intercept form?</h3>

The formula for equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

The y-intercept will occur when x = 0. Thus, from the table, it is clear hat the y-intercept will be c = 2.

Let us find the slope using the first two points;

m = (2 - 0)/(0 - (-15))

m = 2/15

Thus, the equation is;

y = ²/₁₅x + 2

There are two different maps of ohio. The scale on the first map is 1 cm to 10 km. The distance from cleveland to clncinnati is
Ivanshal [37]

1. To answer this question we must keep on mind that we already have the distance from Cleveland to Cincinnati.

2. They tell us that it is 40 centimeters on the first map.

3. If on the first map 1cm = 10km then:

40cm = 10km * 40 = 400km

4. Then the distance from Cleveland to Cincinnati is 400 kilometers.

5. On the second map 1cm = 50km

6. Then we want to know how many centimeters represents 400 kilometers on the second map. Therefore:

400/50= 8

 The answer is: 8 centimeters.
