Find the distance between (4, -1) and (-2, -1). Round answer to the nearest tenth. *

Answers

Answer 1

Answer:

Step-by-step explanation:

You substitute the points into the distance formula. There aren't decimals in this answer, so I don't think you need to round to the nearest tenth. You can also check by plotting these points down on a graph.

(4, -1) (-2, -1)

The y coordinates are the same, you just need to count from -2 to 4. There are 2 steps before 0 and 4 steps after 0. So 2 + 4 is 6.

Answer 2

Answer: 6

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

Work Shown:

[tex]\text{Distance Formula}\\\\d = \sqrt{(x_1-x_2)^2 + (y_1-y_2)^2}\\\\d = \sqrt{(4-(-2))^2 + (-1-(-1))^2}\\\\d = \sqrt{(4+2)^2 + (-1+1)^2}\\\\d = \sqrt{(6)^2 + (0)^2}\\\\d = \sqrt{36}\\\\d = 6\\\\[/tex]

This value is exact. No rounding is needed.

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

A shortcut is to subtract the x coordinates and apply absolute value

So either |x1-x2| = |4-(-2)| = |4+2| = |6| = 6

Or |x2-x1| = |-2-4| = |-6| = 6

This shortcut only works because the y coordinates the same for both points.

On a graph, you can plot the two points and count the spaces between them. You should count out 6 spaces.

how do you get the slope

Answers

Answer:

See below

Step-by-step explanation:

The way to find the slope is to find how many blocks/number it went up and to the side. The number of blocks it went up on the y-axis, in this case, is 3 and it went along the x-axis once. In order to actually find the slope, you need to put the y over the x. So, 3/1 is equal to three, so the slope of this line is 3

Answer:

y2-y1/x2-x1

Step-by-step explanation:

Hello, 40 POINTS + BRAINLIEST to a answer with a long explanation. The question below is just an example, I need to know how to solve exponents.....
The prime factorization of _________ is 2 (to the fourth power) × 5.
How do you solve with the fourth power thing? I am confused....
Please help as soon as possible :)

Answers

Answer:

you times the number by itself the number of times the power is. 10 to the fourth power is 10 times 10 times 10 times 10, etc.

Step-by-step explanation:

For instance 10 to the third power is 1000 because 10 times 10 times 10=1000/

For your example the answer is 2 times 2 times 2 times 2=16. To figure out how much you times it by is if it is to the power of 4, you times it by itself 4 times, power of 5 = times it by itself 5 times, etc. Hope it helps!

What is the slope of the line shown.

Answers

Answer:

The answer is negative one half. If I am wrong let me know because the picture is a little hard to read.

Step-by-step explanation: To find the slope, you look at the Y axis and see where the line crosses perfectly(or goes through) the Y axis first. Then, you look at the x axis and see where the line crosses perfectly on the x axis. For example, the line crosses the Y axis at negative, and the line crosses the X axis at positive 2. The vertical line is the y axis and the horizontal line is the x axis.

Answer:

Step-by-step explanation:

so instantly 40-8.50=31.5

The question is very vague because it doesn't state the number of rides he wants to go on in minimum.

if you do 1.25x25=31.25

According to that, he will leave with a change of 0.25 and obv u cannot go on half a ride...

AOB = -8x + 68

Step-by-step explanation:

AOC = 40°

BOC = 8x - 28

Angle Addition Theorem:

AOB + BOC = AOC

AOB + (8x - 28) = 40

AOB + (8x - 28) + 28 = 40 + 28

AOB + 8x - 8x = 68 - 8x

AOB = -8x + 68

AOB + BOC = AOC

(-8x + 68) + (8x - 28) = 40

-8x + 8x + 68 - 28 =40

0x + 40 = 40

40 = 40

Water flows through a pipe at a rate of 5 quarts every 2 days. Express this rate of flow in cups per year.

Answers

The rate of flow in cups per year is 3645 cups per year.

How to determine the rate of flow in cups per year

To convert the rate of flow from quarts per day to cups per year, we first need to convert quarts to cups and days to years.

1 quart is equal to 4 cups,

So 5 quarts is equal to 5 x 4 = 20 cups.

1 year is equal to 365 days, so

2 days is equal to 2/365 = 1/182.5 years.

So the rate of flow in cups per year is 20 cups / (1/182.5 years) = 3645 cups per year.
