Answer:

Step-by-step explanation:

B) a) 2, 5 , 8 , 11 ......

First term = 2

Second term = 5

Find the common difference.

Common difference = second term - first term

=5 - 2

= 3

Each term is obtained by adding 3 to the previous term.

11 + 3 = 14

14 + 3 = 17

17 +3 = 20

The next three terms are: 14 , 17 , 20

3) 1,4,16,64.....

This is a geometric sequence. Find the common ratio.

Common ratio = second term ÷ first term

= 4 ÷ 1

= 4

Each term is obtained by multiplying previous term by 4.

64 *4 = 256

256 *4 = 1024

1024 * 4 = 4096

The next three terms are: 256, 1024 , 4096.

4) 60, 48 , 36 , 24, .....

This is an arithmetic sequence.Find the common difference.

Common difference = 48 - 60

= -12

Each term is obtained by subtracting 12 ( adding -12) with the previous term.

24 - 12 = 12

12 - 12 = 0

0 - 12 = -12

The next three terms are: 12 , 0 , -12.

5) 1 , 4 , 9, 16,25 ,....

1, 2², 3², 4², 5².....

6² = 6*6 = 36

7² = 7*7 = 49

8² =8 * 8 = 64

The next three terms are: 36, 49 , 64.

It's a pattern- for example question 1 is adding 3 with each numer.
2 + 3 = 5
5+ 3= 8
8 + 3= 11
11+ 3 = 14
And so on

You gotta find the pattern and continue it :)

If the system below were written as a matrix equation, by which matrix could you multiply both sides to obtain a solution?

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

Below are the choices:

A.
[8 -6] 
[-5 4] 
B. 
[4 -3] 
[-2.5 2] 
C. 
[-4 5] 
[6 -8] 
D. 
[-2 2.5] 
[3 -4]

B because it is the inverse of
(4 6) 
(5 8) 

Check 
(4.0 -3)(4 6) = (1 0) 
(-2.5 2)(5 8) = (0 1)

What is the prduct of 33 and 6925?

liubo4ka [24]

Answer:

228525-Look below for steps:)

Step-by-step explanation:

Step 1:

6925

* 33

______

Step 2:

5*3=15

carry the one

3*2+1=7

9*3=27

carry the 2

6*3+2=20

SO your first number is 20775 but we are NOT done yet!

add a zero below 5

5*3=15

carry the one

3*2+1=7

9*3=27 carry the 2

then 6*3+2=20

then add 207750+20775

which equals....

228525

so 228525 is your answer!!!

I really do hope this made sense!

Have a great day!

What are the solutions to the quadratic equation x^2-16=0

maks197457 [2]

Good evening.

This is a incomplete quadratic equation, because it does not have the term bx. Therefore, we can solve this faster with the following strategy:

$\mathsf{x^2 - 16 = 0}$

Add 16 to both sides:

$\mathsf{x^2 - 16 + 16 = 0 + 16}\\ \\ \mathsf{x^2 = 16}$

Take the square root:

$\mathsf{\sqrt {x^2} = \pm\sqrt{16}}\\ \\ \mathsf{\boxed{\mathsf{x = \pm4} }}$

Therefore:

$\boxed{\boxed{\mathsf{S=\{-4, \ +4\}}}}$

In the united states a person ears more than 40,000 pounds of bread in a lifetime if he or she lives to be 80 years old.Does thi

gogolik [260]

Answer:

A reality check quickly reveals that even if "eats" were spelled properly, the statement would still be nonsense.

Step-by-step explanation:

(40,000 pounds / 80 years) = (4,000 pounds / 8 years) = 500 pounds per year

500 pounds of bread per year = an average of a little more than 1-1/3 pound of bread per day, every day of a person's life. My reality meter says that this is a bit much, especially in the USA.
