Answer:

first of all, the formula given is wrong

it is,

$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2)}$

so,

let's say

$(x_2,y_2)=(-1,1) \\(x_1,y_1)=(3,1)$

you can choose arbitrarily, answer will be the same

$= \sqrt{(-1-3)^2+(1-1)^2)}\\=\sqrt{4^2+0}\\=4$

Answer:

-26

Step-by-step explanation:

2 × 3 + 4 − 6^2

PEMDAS

exponents are first in this equation

2 × 3 + 4 − 36

Then multiply

6 +4 -36

Then add and subtract from left to right

10-36

$5\cdot3\cdot4=60$ - the current possible number of plates

after adding 2 letters into the 1st set:
$7\cdot3\cdot4=82$
after adding 2 letters into the 2nd set:
$5\cdot5\cdot4=100$
after adding 2 letters into the 3rd set:
$5\cdot3\cdot6=90$
after adding 1 letter into the 1st set and 1 into the 2nd set:
$6\cdot4\cdot4=96$
after adding 1 letter into the 1st set and 1 into the 3rd set:
$6\cdot3\cdot5=90$
after adding 1 letter into the 2nd set and 1 into the 3rd set:
$5\cdot4\cdot4=80$

The largest possible number of plates after adding two numbers is 100.
So, the largest possible number of additional plates is 100-60=40

Select all of the scales that are equivalent to 3 cm to 4 km.

ra1l [238]

In mathematics, a scale can be described in charts as a marking system at predefined times, which determines the relationship between the units that are being used and their images on the graph, and the further calculation can be defined as follows:

Since in this question, the ratio is between 3 cm to 4 km you can make a $\bold{\frac{3}{4}=\frac{cm}{km}}$ split, and if you are split between 3 and 4, you get the ratio between $\bold{\frac{\frac{3}{4 \ cm}}{1\ km} = \frac{3\ cm}{ 4\ km}}$ .

$\bold{\to \frac{3 }{ 4}= 0.75}$

Therefore the final answer is "0.75 cm to 1 km"

Jimmy has to choose a coat and hat to wear outside. He has a choice of a red (R) or green (G) coat, and a choice of a blue (B) o

Andru [333]

Answer:

{GB,GY,RY,RB}

Step-by-step explanation:

Given : Jimmy has to choose a coat and hat to wear outside. He has a choice of a red (R) or green (G) coat, and a choice of a blue (B) or yellow (Y) hat.

To Find: What is the sample space for Jimmy's possible winter gear?

Solution :

Sample space : In probability theory, the sample space of an experiment or random trial is the set of all possible outcomes or results of that experiment.

To Form sample space

If he choose red coat(R) So, with that coat he can wear blue (B) or yellow (Y) hat.

So, sample space with red coat becomes {RY,RB}

Now If he choose green (G) coat So, with that coat he can wear blue (B) or yellow (Y) hat.

So, sample space with green coat becomes {GB,GY}

So, the sample space for the given situation is {GB,GY,RY,RB}

Hence the sample space for Jimmy's possible winter gear is {GB,GY,RY,RB}
