Find the geometric mean between each pair of numbers. sq root 49 and sq root841

vodomira [7]

<u>Answer:</u>

The geometric mean between each pair of numbers $\bold{\sqrt{49} \text { and } \sqrt{841} \text { is } 14.24}$

<u>Solution:</u>

The Geometric mean between two numbers a and b is given as Geometric mean = $\bold{\sqrt{ab}}$ --- eqn 1

The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root for the numbers.

From question, given that two numbers are $\sqrt{49} and \sqrt{841}$

Hence we can say “a” = $\sqrt{49}$ =7

Similarly “b” = $\sqrt{841}$ = 29

We have to find the geometric mean between “7” and “29”

By using equation 1,

Geometric mean between 7 and 29 = $\sqrt{7 \times 29} = \sqrt{203}$ = 14.24

Hence the geometric mean between $\sqrt{49} \text { and } \sqrt{841} \text { is } 14.24$

Which expression is equivalent to 25^1/3*25^1/6?

Kaylis [27]

$25^{ \frac{1}{3}} \times 25^{ \frac{1}{6} }$

$= 25^{ \frac{1}{3}+ \frac{1}{6} }$

$= 25^{ \frac{1}{2}}$

$= (5^2)^{ \frac{1}{2}}$

$=5$

What is the product -4• [8,-1,-5,9]

xeze [42]

Answer:

The product of given $-4 \cdot \left[\begin{array}{ccc}8\\-1\\-5\\9\end{array}\right]$ is $\left[\begin{array}{ccc}-32 \\4\\20\\-36\end{array}\right]$

Step-by-step explanation:

Consider the given product of a constant and a matrix.

$-4 \cdot \left[\begin{array}{ccc}8\\-1\\-5\\9\end{array}\right]$

To do product we multiply scalar -4 with each element of the matrix given,

$-4 \cdot \left[\begin{array}{ccc}8\\-1\\-5\\9\end{array}\right]= \left[\begin{array}{ccc}-4 \times 8 \\-4 \times -1\\-4 \times -5\\-4 \times 9\end{array}\right]$

On solving further , we get,

$\left[\begin{array}{ccc}-4 \times 8 \\-4 \times -1\\-4 \times -5\\-4 \times 9\end{array}\right]=\left[\begin{array}{ccc}-32 \\4\\20\\-36\end{array}\right]$

Thus, the product of given $-4 \cdot \left[\begin{array}{ccc}8\\-1\\-5\\9\end{array}\right]$ is $\left[\begin{array}{ccc}-32 \\4\\20\\-36\end{array}\right]$
