What are the two ways you can find the distance between points (X1,Y1) and (x2,y2) in the coordinate

The first (and most typical) way to find distance of two points is by using the distance formula.

$distance=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

One alternative is the Manhattan metric, also called the taxicab metric. This option is much more complicated, and rarely used in high school math. d(x,y)=∑i|xi-yi|

<h2>○=> <u>Correct option</u> :</h2><h2> $\color{plum}\tt\bold{(B)}$ </h2><h3>○=> <u>Steps to derive correct option</u> :</h3>

We know that :

$\color{hotpink} \tt \: circumference \: of \: a \: circle\color{plum} = 2\pi r$

So, let the diameter of this circle be x.

Which means :

$=\tt2 \times \pi \times r$

$=\tt 2 \times x \times \pi = 12\pi$

$=\tt 2x\pi = 12\pi$

$=\tt x = \frac{12}{2}$

$= \tt \: x = 6 \: m$

Thus, the radius of the circle Robert drew = 6 m

Since the circle in option B has a radius of 6 m, it is the circle Robert drew.

▪︎<em>Therefore, the correct option is (B)</em>

A bag contains 5 yellow blocks, 2 green blocks and 3 blue blocks. If you choose one block and then another block without putting

Anika [276]

Answer:

The probability that the first block will be green and the second will be yellow is $\frac{1}{9}$ or 0.111.

Step-by-step explanation:

We are given that a bag contains 5 yellow blocks, 2 green blocks and 3 blue blocks.

Also, we choose one block and then another block without putting the first one back in the bag.

<u>Firstly, as we know that Probability of any event is given by ;</u>

Probability of an event = $\frac{\text{Favorable number of outcomes}}{\text{Total number of outcomes}}$

SO, <em>Probability that the first block will be green</em> = $\frac{\text{Number of green blocks}}{\text{Total blocks in the bag}}$

Here, Number of green blocks = 2

Total number of blocks in bag = 5 yellow + 2 green + 3 blue = 10 blocks

So, Probability that the first block will be green = $\frac{2}{10}$

<em>Similarly, Probability that the second block will be yellow</em> =

$\frac{\text{Number of yellow blocks}}{\text{Total number of remaining blocks in the bag}}$

Here, Number of yellow blocks = 5

Total number of remaining blocks in bag = 10 - 1 = 9 blocks {because we haven't put the block back after choosing the first}

So, Probability that the second block will be yellow = $\frac{5}{9}$

<u>Now, Probability that the first block will be green and the second will be yellow</u> = $\frac{2}{10} \times \frac{5}{9}$

= $\frac{1}{9}$ = 0.111

Hence, the required probability is 0.111.

What is the simplest form of the radical expression 8?

Kisachek [45]

The answer oils be 2 square root 2 because 4 times 2 is 8 and because the square root of 4 is 2 you would move that 2 to the outside and keep the other two on the inside of the square root.

Please hurry

Answer: y = -6x -10

Step-by-step explanation:

The equation is y = mx + b

1. m is the slope so you can replace m with -6.

2. You are given a point, so you can replace variables x and y with the point. The equation should now look like this:

y = -6x + b

-4 = -6(-1) + b

3. Then multiply -6 and -1 to get 6. Now you are left with -4 = 6 + b

4. To solve for b you must get it alone. Right now B isn't alone because a 6 is being added to b. To get b alone you need to subtract 6. Now your equation should look like this: -4 - 6 = B

5. Get a calculator or use mental math and you will get B = -10.

6. Then plug b and m into y = mx + b, and you should get y = -6x - 10
