Step-by-step explanation:

Hey, there!!

The given points are A(5,1) and B(-3,-5)

We have, distance formulae for AB is,

ab =  \sqrt{ {(x2 - x1)}^{2}  + ( {y2 - y1)}^{2} }

ab =  \sqrt{( { - 3 - 5)}^{2}  + ( { - 5 - 1)}^{2} }

ab =  \sqrt{(  { - 8)}^{2} + ( { - 6)}^{2}  }

ab =  \sqrt{64 + 36}

ab =  \sqrt{100}

Therefore, the distance between AB points is 10 units.

The ceiling of Stacy's living room is a square that is 25 ft long on each side. Stacy
Brut [27]

Answer:

A. 35 ft.

B. 35 ft

Step-by-step explanation:

Please see attached photo for diagram.

A. Determination of the diagonal using pythagorean theorem.

A square has all sides equal. Thus, the diagonal of the square can be obtained as follow:

Ist leg (L₁) = 25 ft

2nd leg (L₂) = 25 ft

Diagonal (d) =?

d² = L₁² + L₂²

d² = 25² + 25²

d² = 625 + 625

d² = 1250

Take the square root of both side

d = √1250

d = 35 ft

B. Determination of the diagonal using trigonometry.

Since all the sides in a square are equal, the angle between each leg will be 90°. Thus, the diagonal will bisect the angle between the two leg equally i.e

Angle between Diagonal and each leg = 90/2 = 45°

Finally, we shall determine the length of the diagonal. This can be obtained as follow:

Angle θ = 45°

Opposite = 25 ft

Hypothenus = d

Sine θ = Opposite / Hypothenus

Sine 45 = 25 / d

0.7071 = 25 / d

Cross multiply

0.7071 × d = 25

Divide both side by 0.7071

d = 25 / 0.7071

d = 35 ft

Play the four digit 3,5,7,and 9 into the boxes pure in the position that would give the greatest results in the true numbers are
Bad White [126]
<h2>Answer:</h2>

- 9 3 x 7 5

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

To get the combination that would yield the greatest result if the true number are multiplied,

<em>i. multiply each given combination</em>

73 x 95 = 6935

79 x 53 = 4187

97 x 35 = 3395

93 x 75 = 6975

<em>ii. get the largest result from the results calculated above in (i)</em>

The greatest of the results is 6975, therefore the digits should be placed like so;

<u> 9 </u>  <u> 3 </u>

<u> 7 </u>  <u> 5 </u>

Please don’t just comment for points
masha68 [24]
1. no because 2x+10 is not equal to 2x+7
2. no. you cant add una like terms so 4x+4 doesn’t equal 8x
3. yes. the terms still retain their same value although they are not in the same order
4. yes. when u distribute the -3, you get -3x-6 which is of course equal to -3x-6

when you are dividing two decimals how can you check whether you have divided the decimals correctly?
Mice21 [21]

Dividing two decimals means that we need to make the following math operation:

\frac{p}{q} \\ \\ where \ p \ and \ q \ are \ two \ decimals

According to the following definition:

If \ p \ and \ d \ are \ two \ real \ numbers \ (two \ decimals) \ it \ is \ true \ that:\\ \\  p=d\times q+r \\ \\ where:\\ \\ p:Dividend \\ d:Divisor \\q:Quotient \\ r:Reminder


We can prove that our result is correct by multiplying the divisor by the quotient plus the reminder and verifying that this result matches the dividend. Also, we can use a calculator to prove that.
