What is the distance between (-2,-8)(7,-3)

Answers

Answer:

[tex]\sqrt{106}[/tex] or 10.29563

Step-by-step explanation:

Use the distance formula to determine the distance between the two points.

[tex]d = \sqrt{(x_{2} -x_{1})^{2} + (y_{2} - x_{1})^{2} }[/tex]

d = distance

[tex](x_{1}, y_{1})[/tex] = coordinates of the first point

[tex](x_{2}, y_{2})[/tex] = coordinates of the second point

Answers

Answer:

b. the slopes of both functions are positive

Step-by-step explanation:

hope this helps :)

Answer:

C. The slope of function A is positive and the slope of function B is negative.

Step-by-step explanation:

For this problem, you need to determine the slope of each function.

For function A:

You're given y = (1/4)x - 2/3, which is in slope-intercept form y = mx + b. The slope of an equation in slope intercept form is given by m.

So the slope for function A is 1/4.

For function B:

You're given a list of (x, y) points, so use the definition of the slope = [tex]\frac{y2-y1}{x2-x1}[/tex], which gives you the slope from any two (x, y) points on the line. Let's take the first and second points (2, -8) and (4, -9)

Slope = [tex]\frac{-9-(-8)}{4-2} = \frac{-1}{2}[/tex].

Therefore, the slope of function A is positive and the slope of function B is negative.

What is the volume of the pyramid?
A. 624 cm3
B. 1,872 cm
C. 2, 808 cm
D. 4,212 cm
E. 8, 424 cm

Answers

Answer:

C. 2, 808 cm^3

Step-by-step explanation:

Given that

The base of the pyramid is 18 centimeters

And, the height of the pyramid is 26 centimeters

We need to find out the volume of the pyramid

As we know that

The volume of the pyramid is

= 1 ÷ 3 × base^2 × height

= 1 ÷3 × 18^2 × 26

= 2,808 centimeter^3

Hence, the correct option is c.

Find the values of x and y that make these triangles congruent by the HL Theorem.

Answers

Answer:

x = 3 ; y=2

Step-by-step explanation:

to simplify the work we can build a system of two equations

2x+3 = 3y+3

x = y+1

we can now substitute the value of x in the first equation

2(y+1)+3 = 3y+3

2y + 2 + 3 = 3y+3

2y + 5 = 3y+3

y = 2

now we can subisitute the value of y in the first equation

x = 2 + 1 = 3

Verify

2(3)+3 = 6+3 = 9

3(2) + 3 = 6 + 3 = 9

2+1 = 3

Andy estimated that he would need 73 feet of lumber for a tree house project. He later found that the actual amount of lumber needed was 62 feet. What was the percent error of Andy's estimation?

Answers

Answer:

17.74%

Step-by-step explanation:

The formula for percent error is given as:

|Estimated value - Actual value|/Actual value × 100

From the above question:

Estimated value = 73 feet

Actual value = 62 feet

Hence,

Percent error = |73 - 62|/62 × 100

= 11/62 × 100

= 17.741935484%

Approximately , percent error = 17.74%

Therefore, the percent error of Andy's estimation is 17.74%

From a barrel of colored marbles, you randomly select 1 blue 6 yellow 7 red 4 green and 6 purple marbles

Answers

Complete question :

From a barrel of colored marbles, you randomly select 1 blue 6 yellow 7 red 4 green and 6 purple marbles. Find the experimental probability of randomly selecting a marble that is NOT yellow.

Answer:

Step-by-step explanation:

Total number of marbles :

Blue = 1 ; yellow = 6 ; red = 7 ; green = 4 ; purple = 6

Total = (1 + 6 + 7 + 4 + 6) = 24 marbles

Probability of selecting marble that is not yellow :

Number of marbles that aren't yellow / total number of marbles

Marbles that aren't yellow = 24 - 6 = 18

P(selecting a marble that isn't yellow) = 18 / 24 = 3/4

Read the text from the following website: www.growingnation.orgA Growing NationAfter the American Revolution, the newly formed United States realized that it lacked room to grow. The states created in the Declaration of Independence in 1776 were limited in size. As the population increased, more people were competing for the same amount of land. Consequently, land became more expensive, and overcrowding became an issue. The thirteen states were bordered by the Atlantic Ocean and the territories of other nations. If the United States was going to have a future, it needed to increase its territory.President Thomas Jefferson believed that for Americans to be virtuous and free, they needed to farm land. He wanted to expand westward to create more farmland. Jefferson also wanted to obtain the Port of New Orleans at the mouth of the Mississippi River so farmers could easily transport their goods. He facilitated the purchase of New Orleans and the rest of the French territory from France in 1803 for $15 million. This new land was called the Louisiana Territory and stretched partway across the continent. It was the first step in expanding the United States.The purchase of the Louisiana Territory led to a pattern of westward expansion through payment, negotiations, and conflict. The United States purchased Florida from Spain with the Florida Purchase Treaty of 1821. Instead of paying Spain a set amount, the United States would pay the $5 million Americans claimed were owed to them by Spain. After Texas declared independence from Mexico, it was annexed by the United States and became an official state in 1845. Another land controversy occurred between Great Britain and the United States, as both countries claimed the Oregon region. The dispute was settled in the 1846 Oregon Treaty, which separated the countries by the line of the 49th parallel. Mexico refused to let the United States buy California and New Mexico, so the two countries eventually went to war. Because the Americans won the war, the United States was able to buy lands in the Southwest in 1848. The United States paid Mexico $10 million for an area of land in the Southwest in the 1853 Gadsden Purchase, stretching its borders from sea to sea.According to information in the text feature, in what year did the United States officially obtain land with access to the Pacific Ocean?1845184818211846 673,000 in numeric help!!
