Find an expression for the nth term (tn) in each of the following sequence:

2, 6, 10, 14, 18…

Answers

Answer:

The answer is 34

Step-by-step explanation: I just have a big brain

Answer: [tex]t_n = 4n - 2[/tex]

===========================================

Work Shown:

The first term is a = 2 and the common difference is d = 4, since we're adding 4 to each term to get the next term.

[tex]t_n = \text{nth term of arithmetic sequence}\\\\t_n = a+d(n-1)\\\\t_n = 2 + 4(n-1)\\\\t_n = 2 + 4n - 4\\\\t_n = 4n - 2[/tex]

Which is the answer.

--------------------------------

If you were to plug in say n = 3, then we get

[tex]t_n = 4n - 2\\\\t_3 = 4(3) - 2\\\\t_3 = 12 - 2\\\\t_3 = 10[/tex]

showing that 10 is the third term, which matches with what the original sequence shows. I'll let you check the other values of n to fully confirm the answer.

A triangle can have sides of 12, 19, and 30.
True or false

Answers

Answer:

True

Step-by-step explanation:

According to the Triangle Inequality, the sum of any two sides of a triangle has to be greater than the third side. 12+19 = 31 which is more than 30 so a triangle can have sides of 12, 19 and 30.

Simplify the following expression. (19x + 4y) + (49x + 32y)

Answers

Answer: 68x + 36y

Step-by-step explanation:

Combine Like Terms:

= 19x + 4y + 49x + 32y

= (19x + 49x) + (4y + 32y)

= 68x + 36y

Hope this helped you!

Answer:

68x + 36y

Step-by-step explanation:

You can compeletely get rid of the parenthesis because it is addition through and thorough.

You have 19x + 4y + 49x + 32y

You can combine like terms to get

19x +49x which is 68x

and

4y + 32y which is 36y

You now have 68 + 36y which cannot be simplified anymore because the variables are different.

Hope this helps!

A bus travels at a speed of 40 miles per hour and reaches Hogville in 40 minutes. If a cab takes 35 minutes to reach the same spot, determine the speed at which it traveled.

Answers

Answer:

45.7miles per hour

Step-by-step explanation:

40mins = 2/3 hour

the bus travelled (2/3 x 40) miles = 80/3 miles

the cab took 35 mins (which is 7/12 hour) so it's speed is (80/3)/(7/12) miles/hour = 45.714 miles/hour (5 s.f.)

List 4 benefits to you personally when working with a group to accomplish a project.Big brain for best answer! Select the correct text in the passage. The following passage was adapted from text by the Oklahoma Historical Society. Which part of the passage best explains why the United States did not want to allow Indian Territory to become its own state? The goal of the Sequoyah Convention was to draft a constitution for a proposed single state made from Indian Territory. Delegates were chosen in mass meetings held across Indian Territory. Until 1903, the Five Civilized Tribes and other tribes in Indian Territory had generally opposed all local and national efforts for statehood. In 1905, the end of tribal governments loomed, as prescribed by the Curtis Act, and the tribes knew they faced the prospect of joint statehood with Oklahoma Territory. Their desire for Indian Territory to be admitted as its own state resulted in the Sequoyah Convention, which met August 21 and 22 and September 5 through September 8, 1905. The convention drafted a constitution that was about 35,000 words in length, which was perhaps the convention's greatest contribution to Oklahoma history. But territorial leaders realized that the Republican-led US Congress was unlikely to admit a heavily Democratic Indian Territory. Still, single-state supporters and Indian Territory leaders pressed onward. However, the US Congress refused to consider statehood for the state of Sequoyah. Joint statehood, the joining of Indian Territory and Oklahoma Territory to form Oklahoma, occurred on November 16, 1907. Reset Next PLEASE HELP!
