Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 20)(0,20) and (6, 1280)(6,1280).

Answers

Answer:

[tex]y=20(2)^x[/tex]

Step-by-step explanation:

We want to write an exponential function that goes through the points (0, 20) and (6, 1280).

The standard exponential function is given by:

[tex]y=ab^x[/tex]

The point (0, 20) tells us that y = 20 when x = 0. Hence:

[tex]20=a(b)^0[/tex]

Simplify:

[tex]20=a(1)\Rightarrow a=20[/tex]

So, our exponential function is now:

[tex]y=20(b)^x[/tex]

Next, the point (6, 1280) tells us that y = 1280 when x = 6. Thus:

[tex]1280=20(b)^6[/tex]

Solve for b. Divide both sides by 20:

[tex]64=b^6[/tex]

Therefore:

[tex]b=\sqrt[6]{64}=2[/tex]

Hence, our function is:

[tex]y=20(2)^x[/tex]

What is the slope of the line that passes through the points (0, -4)) and (-2, -1)

Answers

Answer:

Step-by-step explanation:

y = mx + b

m is the slope (what you want)

b is the y-intercept, which is the value of y when x = 0

Oh, right, we already have b, isn't that great!

Given point (0, -4), so b = -4

Point (-2, -1), where x = -2 and y = -1

-1 = -2m -4 (solve for m)

3 = -2m

m = -3/2

Check:

y = -3x/2 -4

y = -3(-2)/2 -4  -> should get y = -1

y = 3 -4 = -1

Yay, we have the answer!

Please help if you know the answer!!Read the excerpt from Votes for Women:At the Seneca Falls Convention in July 1848, women like Lucretia Mott and Elizabeth Cady Stanton signed the Declaration of Sentiments, a document expressing their concerns about the role of women in the United States. For example, at the time married women could not own property, and the education and employment of women was limited. These women decided that to change the law, women needed to be able to vote. Some thought that peaceful methods were the best way for the Women's Suffrage Movement to obtain its goal, while others believed that a more aggressive strategy was necessary.The peaceful approach in the Women's Suffrage Movement changed the United States over time. At first, there was resistance to the idea of women having the vote. Many believed that the practice of politics was masculine and men should vote on behalf of their wives and daughters. When African American men were granted the right to vote in the 15th Amendment, women of any race were not included. This decision discouraged many women, but they still organized themselves into groups, like the National American Woman Suffrage Association, in order to campaign for the vote. They argued that voting women would benefit society, and published newspaper articles and other literature about women's rights. From 1878 until 1920, the idea of women's suffrage was brought before Congress every year. In the meantime, women also campaigned for the vote in different states. During World War I, many women did jobs regularly done by men. Their contributions to the United States and the influence of Carrie Chapman Catt caused President Woodrow Wilson to finally support women's suffrage. The peaceful approach changed opinions over time and ultimately led to the 19th Amendment.--------------------------------------------------------------------------------------------What evidence does the author use to support the fact that the peaceful approach was the best way for women to get the vote?
