Step-by-step explanation:

x =  \sqrt{ {26}^{2}  -  { (\frac{48}{2} })^{2} }  \\  = \sqrt{ 676  -  { (24)}^{2} }  \\  \\  =  \sqrt{676 - 576}  \\  \\   = \sqrt{100}  \\  \\   \therefore \: x= 10

√72 what is the non-perfect simplefied square root radical
Lostsunrise [7]

For simplifying radicals, remember the product rule of radicals: √ab = √a x √b . This radical is simplified as such:

√72 = √9 x √8 = 3 x √4 x √2 = 3 x 2 x √2 = 6√2

In short, the simplified radical of √72 is 6√2.

If SF = 5x + 2, SK = 27, and KF = 3x - 1,<br> find KF.
kondor19780726 [428]

Answer:

KF = 35

Step-by-step explanation:

Since it's a line with K in the middle, we know that the distance SF is the same as SK + KF.

(Start at S, first go to K, then continue to F. You've traveled the same distance as from S to F.)

SF = SK + KF

Let's put in the values we got.

5x + 2 = 27 + (3x -1)

Opening the parenthesis.

5x + 2 = 27 + 3x - 1

5x + 2 = 26 + 3x

Now let's subtract 3x from both sides.

2x + 2 = 26

Now, subtract 2 from both sides.

2x = 24

If we divide by 2...

x = 12

We know that...

KF = 3x -1

Since x is 12, let's put that in.

KF = 3 * 12 - 1 = 36 - 1 = 35

Answer: KF is 35 !

If k‐th term of a sequence is ak = ( -1) ^k(2-k)k/2k-1
max2010maxim [7]

Given:

kth term of a sequence is

a_k=\dfrac{(-1)^k(2-k)k}{2k-1}

To find:

The next term a_{k+1} when k is even.

Solution:

We have,

a_k=\dfrac{(-1)^k(2-k)k}{2k-1}

Put k=k+1, to get the next term.

a_{k+1}=\dfrac{(-1)^{k+1}(2-(k+1))(k+1)}{2(k+1)-1}

If k is even, then k+1 must be odd and odd power of -1 gives -1.

a_{k+1}=\dfrac{(-1)(2-k-1)(k+1)}{2k+2-1}

a_{k+1}=\dfrac{(-1)(1-k)(1+k)}{2k+1}

a_{k+1}=-\dfrac{1^2-k^2}{2k+1}    [\because (a-b)(a+b)=a^2-b^2]

a_{k+1}=-\dfrac{1-k^2}{2k+1}

Therefore, the next term is a_{k+1}=-\dfrac{1-k^2}{2k+1}.

Factorise: (a^4 - 8a^2b^2 + 16b^4) -81
Schach [20]

Answer:(a² - 4b² - 9)(a² - 4b² + 9)

(a^4 - 8a²b² + 16b^4) - 81

= [(a²)² - 2.4a²b² + (4b²)²] - 9²

= (a² - 4b²)² - 9²

= (a² - 4b² - 9)(a² - 4b² + 9)
