Answer:

5

Step-by-step explanation:

Use the distance formula d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

insert the numbers into the formula d=\sqrt{(2+1)^2+(0-4)^2}

2+1=3 and 0-4=-4

3^2 =9 and -4^{2} = 1

9+16=25

the square root of 25 is 5

Answer:

The distance would be 5

Step-by-step explanation:

You would have to use the distance formula, which is:

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

The coordinate 2 is x_{2} and coordinate -1 is x_{1}

And the coordinate 0 is y_{2} and 4 is y_{1}

So now we would put those values into the formula as follows:

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

According to PEMDAS, we would have to evaluate parenthesis first

*Keep in mind that two negative signs equal a positive

d= \sqrt{(3)^{2}-(4)^{2}}

Following with PEMDAS, we'll now square both numbers

d=\sqrt{9+16}

Evaluate

d=\sqrt{25}

And simplify

d= 5

What is the value of x?
anzhelika [568]
We know that 5x-3x =2x

So x(5x-3x)=x×2x

=(2x)^2

=4x^2

Which is given as 18.

X^2=18÷4

=4.5

So x=root over 4.5

Which is approximately 2.25

The director of admissions at Kinzua University in Nova Scotia estimated the distribution of student admissions for the fall sem
Naily [24]

Answer: 1406

Step-by-step explanation:

Given Table :

Admissions   Probability

1,040                0.3

1,320                0.2

1,660                0.5

Now, the expected number of admissions for the fall semester is given by :-

E(x)=p_1x_1+p_2x_2+p_3x_3\\\\\Rightarrow\ E(x)=0.3\times1040+0.2\times1320+0.5\times1660\\\\\Rightarrow\ E(x)=1406

Hence, the expected number of admissions for the fall semester = 1406

What is the value of log 7 343?–3 -1/3 1/3 3
xeze [42]

Answer: 3

Step-by-step explanation:

Given :

Log_{7} 343

We need to write 343 in index form of 7.

343 is the same as 7^{3} , replacing 343 with 7^{3} , we have

Log_{7} 7^{3}

Recall one on the law of Logarithm :

Log_{a}b^{c} can be written as c Log_{a}b

So, Log_{7} 7^{3} can be written as ;

3Log_{7} 7

Also from the laws of Logarithms , Log_{a} a = 1

so , Log_{7}[/tex] 7 = 1

The solution then becomes

3 x 1 = 3

Therefore :

Log_{7} 343 = 3
