Answer:

(5)

Step-by-step explanation:

The given two points are:

A(3,k) and B(h,4)

Now, using the distance formula that is=\sqrt{(y_{2}-y_{1})^{2}+(x_{2}-x_{1})^{2}}.

In the given points, y_{2}=4,y_{1}=k,x_{2}=h and x_{1}=3, thus,

\sqrt{(y_{2}-y_{1})^{2}+(x_{2}-x_{1})^{2}}=\sqrt{(4-k)^{2}+(h-3)^{2}}

which is the required equation, hence option 5 is correct.

<h2>Answer:</h2>

The correct answer is:

      2)   \sqrt{(k-4)^2+(3-h)^2}

      3)   \sqrt{(h-3)^2+(4-k)^2}

      4)    \sqrt{(3-h)^2+(k-4)^2}

      5)    \sqrt{(4-k)^2+(h-3)^2}

<h2>Step-by-step explanation:</h2>

We can find the distance between two points with the help of the distance formula.

The distance between two points (a,b) and (c,d) is calculated by the formula:

Distance=\sqrt{(c-a)^2+(d-b)^2}

which is similar to the expression:

Distance=\sqrt{(-(a-c)^2)+(-(b-d)^2)}\\\\i.e.\\\\Distance=\sqrt{(a-c)^2+(b-d)^2}

or

Distance=\sqrt{(a-c)^2+(d-b)^2}

or

Distance=\sqrt{(c-a)^2+(b-d)^2}[/tex]

Here we are asked to find the distance between the point A(3,k) and B(h,4)

The distance is given by:

Distance=\sqrt{(h-3)^2+(4-k)^2}

which is also written by:

Distance=\sqrt{(h-3)^2+(k-4)^2}

or

Distance=\sqrt{(3-h)^2+(4-k)^2}

or

Distance=\sqrt{(3-h)^2+(k-4)^2}

Answer:

The answer is 9.43 cm.

Step-by-step explanation:

The formula for circumference is πd or 2πr.

The diameter is the radius times 2. 1.5 times 2 is 3.

3 times π is about 9.43.

I hope this helps! :)

Factorise <br> a) 4p²-81<br> b) x²-13x+36
taurus [48]

Answer:

A = (2p + 9) (2p - 9)

B = (x - 9) (x - 4)

Step-by-step explanation:

For A : Rewrite 4p^2 as (2p)^2.

(2p)^2−81

Rewrite 81 as 9^2.

(2p)^2−9^2

Since both terms are perfect squares, factor using the difference of squares formula, a^2 − b^2 = ( a + b ) ( a − b ) where a = 2p and b = 9 .

(2p + 9) (2p − 9)

For B : Consider the form x^2 + bx + c . Find a pair of integers whose product is c and whose sum is b . In this case, whose product is 36 and whose sum is − 13 .

-9, -4

(x - 9) (x - 4)

I hope this helps.

Jessie graphed one of the lines in a system of equations: Y=3x-2 If the system has an infinite number of solutions, which statem
katen-ka-za [31]

Answer:

2, 4, and 5

Step-by-step explanation:

There are three states that a system of linear equations can be in. Intersecting, parallel, and overlapping. Intersecting results in one solution, parallel results in none, and overlapping makes all solutions that are on the line correct. The question says that there are infinite solutions, so it must be overlapping. We can immediately rule out the first one because only points that lie on the line can be solutions. Since we know that the system has all of the solutions shown, 2 has to be true. 3 is the same idea. When you plug the x value (20) into the equation, you get the y value (58) meaning that it must be true. 5 is stated above.
