What is the next term in the geometric sequence -1 -2 -4

Answers

Answer: -8

Step-by-step explanation:

We must remember that, in geometric sequences, the ratio between the consecutive terms is constant.This is called "Common ratio" and is represented with "r".

We need to find the common ratio of this geometric sequence:

Divide one term by the previous term:

$r=(-4)/(-2)\n\nr=2$

Then, the next term asked in the exercise can be found by multiplying -4 by 2.

Therefore, this is:

$next\ term=(-4)(2)\n\nnext\ term=-8$

Answer:

-8

Step-by-step explanation:

r=2

so multiply third term by 2

Numbers like 10, 100, 1,000, and so on are called ___________.What is the correct term or number to complete the sentence.

Answers

The answer is powers of ten. A power of ten is 10 multiplied by itself the exponent number of times. For example, 10 = 10^1. 100 = 10 * 10 = 10^2. 1000 = 10 * 10 * 10 = 10^3. The number of zeros in the power of ten must match its exponent. For instance, 1000 has 3 zeros so the exponent is 3: 1000 = 10^3.Hope this helps. Let me know if you need additional help!

Answer:

y=mx+c

We have to find the value of m and c.

Let's substitute the value of x and y from the table.

When x=1, y=15,

15= m(1)+c

m +c= 15 ------(1)

Now substitute another set of x and y values.

When x=2, y=24,

24= m(2)+c

2m +c= 24

c= 24 -2m ------(2)

Let me rewrite the two equations so that it is clearer for you to see.

m + c= 15 -----(1)

c = 24 -2m -----(2)

subst. (2) into (1):

m+ 24-2m= 15

-m= 15-24 (bring constants to 1 side, m terms to the other)

-m= -9 (simplify)

m= 9 ( divide by -1 throughout)

subst. m=9 into (2):

c= 24 -2(9)

c= 24-18

c= 6

Thus, the equation is y=9x+6.

When the cat is 3 years old, x=3.

When x=3,

y= 9(3)+6

y= 33.

Hence, the cat is 33 years old in human years.

36 is what percent of 40

Answers

36 is 90 percent of 40.

We have,

To determine what percentage 36 represents in relation to the whole value of 40.

To do this, we use the formula for finding a percentage:

Percentage = (Part / Whole) x 100

In this case, the part is 36, and the whole is 40.

By substituting these values into the formula, we get:

Percentage = (36 / 40) x 100

Simplifying the calculation:

Percentage = 0.9 x 100

Percentage = 90

This means that 36 is equal to 90% of 40.

In other words, 36 represents 90% of the totalvalue of 40.

Thus,

36 is 90% of 40.
