  1. After demanding both political and military action on removing Native American Indians from the southern states of America in 1829, President Andrew Jackson signed this into law on May 28, 1830. Although it only gave the right to negotiate for their withdrawal from areas to the east of the Mississippi river and that relocation was supposed to be voluntary, all of the pressure was there to make this all but inevitable. All the tribal leaders agreed after Jackson’s landslide election victory in 1832.

    It is generally acknowledged that this act spelled the end of Indian Rights to live in those states under their own traditional laws. They were forced to assimilate and concede to US law or leave their homelands. The Indian Nations themselves were force to move and ended up in Oklahoma.

    The five major tribes affected were the Cherokee, Chickasaw, Choctaw, Creek, and Seminole. These were called The Civilised Tribes that had already taken on a degree of integration into a more modern westernised culture, such as developing written language and learning to read and write.

    It overturned the more concessionary attitude of ex-President George Washington that aimed for ‘acculturation’ after debate with the Indian Nations. Even in those distant times, there was heated debate in congress with such famous names as the future president Abraham Lincoln and Davy Crockett speaking out against it. Now it is considered with serious negativity by all involved.

  2. [tex]h(x)=9x-18[/tex]

    Explanation:

    1. Given  

                    [tex]f(x)=\dfrac{1}{9}x+2[/tex]

    2.  Replace the name of the function with the variable

                     [tex]y=\dfrac{1}{9}x+2[/tex]

    3. Swift x and y

                   [tex]x=\dfrac{1}{9}y+2[/tex]

    4. Solve for y

                    [tex]x-2=\dfrac{1}{9}y[/tex]

                    [tex]9(x-2)=y[/tex]

                     [tex]9x-18=y[/tex]

                     [tex]y=9x-18[/tex]

    5. Name the function

                       [tex]h(x)=9x-18\leftarrow answer[/tex]

  3. Rudolf Virchow's concluded that all cells come from preexisting cells.

    Explanation: Rudolph Virchow state that 'Omnis cellula e cellula' which means that every cells arise from preexisting cells. Until Virchow came out with this theory, it was believed that new cells were created from a fluid called blastema ( it was believed that the imbalance caused disease).

    Rudolf Virchow's lay the ground work on cellular pathology ( that is the study of disease at the cellular level). His work made it more clear that diseases occur at the cellular level and not blastema as believed. Diseases were diagnosed more accurately by scientist due to Rudolf Virchow's work.

  4. He concluded that all cells come from preexisting cells.

    Explanation:

    Rudolf Virchow while building on the work of Theodore Schwann formulated a part of the cell theory which opined that cells arose from pre-exsiting cells which disproved the theory of spontaneous generation

    Although this assertion has earlier been made by another scientist, Robert Remak in 1852, Schwann did not accept until later until after series of investigations.  Schwann was later accused of publishing the work of Robert Remak as his in 1855.

    The other parts of the cell theory include:

    All living organisms are made up of cells which could be prokaryotic or eukaryoticCells are the basic unit of life.

  5. W and Z

    Explanation:

    Work done is the force applied to move a body through a distance in a specific direction.

     Work done  = Force x distance

    Now let's use this formula to solve for work done;

    Scenario W: A force of 75 N moves a box 15 m.

          Work done  = 75 x 15  = 1125J

    Scenario X: A force of 100 N moves a box 12 m.

           Work done  = 100 x 12   = 1200J

    Scenario Y: A force of 50 N moves a box 20 m.

          Work done  = 50 x 20  = 1000J

    Scenario Z: A force of 25 N moves a box 45 m.

          Work done  = 25  x 45  = 1125J

    Choices W and Z is the right option in which the same amount of work is done on the box.

  6. The Indian Removal Act was signed into law by President Andrew Jackson on May 28, 1830, authorizing the president to grant unsettled lands west of the Mississippi in exchange for Indian lands within existing state borders. A few tribes went peacefully, but many resisted the relocation policy.

    More than 8,000 Native Americans died during several waves of relocations.

    If you need more information google stuff about the trail or tears... everything that happened during it was because of President Andrew.

    Hope this helped.

  7. 5040

    Step-by-step explanation:

    multiplying is just repeated addition so this would be the same as adding 8+8 5 times and 21+21 6 times

  8. It is statistically significant that mean of difference scores is different from 0

    Step-by-step explanation:

    Subject    Bar 1      Bar 2      Difference

    1                 20          40            20

    2                 18          25             7

    3                 24          38            14

    4                 14           27            13

    5                 5            31             29

    6                 26          21             -5

    7                 15           32            17

    8                 29          38            9

    9                 15           25           10

    10                9             18           9

    Mean of difference =[tex]\frac{Sum}{10}=\frac{123}{10}=12.3[/tex]

    Standard deviation s =[tex]\sqrt{\frac{(x_i-\bar{x})^2}{n}}=8.93[/tex]

    Null Hypothesis : mean of difference scores is 0 : [tex]H_0:\mu=0[/tex]

    Alternate Hypothesis : mean of difference scores is different from 0 : [tex]H_a:\mu \neq 0[/tex]

    We will use t test for unpaired

    [tex]t = \frac{x-\mu}{\sqrt{\frac{s^2}{n-1}}}\\t = \frac{12.3-0}{\sqrt{\frac{8.93^2}{10-1}}}\\t=4.13[/tex]

    Level of significance (two tailed) =[tex]\alpha = 0.05[/tex]

    Degree of freedom = n-1 = 10-1 =9

    Using calculator

    The p-value is .002559.

    p value < α

    So ,we reject null hypothesis

    So, It is statistically significant that mean of difference scores is different from 0
