Answer:

\boxed {d = \sqrt{194}}

Step-by-step explanation:

Use the <u>Distance Formula</u> to help you find the distance between the two given points:

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

First point: (x_{1}, y_{1})

Second point: (x_{2}, y_{2})

-Substitute the two given points onto the formula:

First point: (3, 9)

Second point: (-10, 4)

d = \sqrt{(-10 - 3)^{2} + (4 - 9)^{2}}

-Then, you solve for the distance:

d = \sqrt{(-10 - 3)^{2} + (4 - 9)^{2}}

d = \sqrt{(-13)^{2} + (-5)^{2}}

d = \sqrt{169 + 25}

\boxed {d = \sqrt{194}} (since the number cannot be square rooted, the number will stay the same)

Therefore, the distance is \sqrt{194}.

(-8y^2+6y-1)+(-8y^2+8y+1)-(-3y^2+9y-9)
taurus [48]

The answer of the given equation is  -13y^{2} -11y+7

Step-by-step explanation:

The given equation can be written as,

(-8y^{2}+6y-1) +(-8y^{2}+8y+1)-(-3y^{2}+9y-9)

= -8y^{2} +6y-1-8y^{2}-8y -1+3y^{2}-9y+9

[Taking same powered variables together we get,]

=(-8y^{2}-8y^{2}+3y^{2}) +(6y-8y-9y)-1-1+9

= -13y^{2} -11y+7

Here the answer.

Prove that 2n^3 + 3n^2 + n is divisible by 6 for every integer n &gt; 1 by mathematical induction. (7 marks)
notka56 [123]

Answer:

The answer is True

Step-by-step explanation:

A <em>mathematical induction</em> consists in only 2 steps:  

<u>First step</u>: Show the proposition is true for the first one valid integer number.

<u>Second step</u>: Show that if any one is true then the next one is true  

Finally, if first step and second step are true, then the complete proposition is true.

So, given 2*n^3+3*n^2+n

First step: using and replacing n=2 (the first valid integer number >1)

2*(2)^3 +3*(2)^2+2=30

\frac{30}{6} =5

As the result is an integer number, so the first step is true.

Second step: using any next number, n+1, let it replace

2*(n+1)^3+3*(n+1)^2+(n+1)\\2*(n^3+3*n^2+3*n+1)+3*(n^2+2*n+1)^2+(n+1)\\2*n^3+6*n^2+6*n+2+3*n^2+6*n+3+n+1\\(2*n^3+3*n^2+n)+(6*n^2+12*n+6)

As the First step is true, we know that

2*n^3+3*n^2+n=6*k,

So let it replace in the previous expression

6*k+6*(n^2+2*n+1)\\6*[k+(n^2+2*n+1)]

Finally

\frac{6*[k+(n^2+2*n+1)]}{6} =k+(n^2+2*n+1)

where the last expression is an integer number

So the second step is true, and the complete proposition is True

I have a problem with statistics. What are p-values?
Rashid [163]
A p-value is the probability of getting, in another study, a test statistic that is more extreme than the one obtained in your study if a series of assumptions hold.
