Taking a sqrt=taking a 1/2 power, so when you take a power of a power, you multiply them. So you’re finding 10.3^(3/2).

Hey!!

Find the square root of cube of 10.3

<em>The equation would like : </em>

... [\sqrt{10.3^{3} }

What is √ ?

=> √ is the power to 1/2.

... \sqrt{10.3^{3} }

... \sqrt{1092.727}

... \sqrt{100} * \sqrt{10.92727}

... 10 * 3.305

... 33.05\\

Hope my answer helps!!

The midpoint of an is me -2,-6 if the coordinates of a are 1,-4 what are the coordinates of b
nalin [4]

Given:

\text{ The midpoint of }\bar{AB}\text{ is }M(-2,-6).\text{ Co-ordinates of A are }(1,-4).

Required:

What are the coordinates of B?

Explanation:

We know the mid-point of of line between two points is:

(x,y)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

Now, let point B(x1, y1)

\begin{gathered} (-2,-6)=(\frac{1+x_1}{2},\frac{-4+y_1}{2}) \\ \text{ Equate Co-ordinates} \\ \frac{1+x_1}{2}=-2 \\ 1+x_1=-4 \\ x_1=-5 \\ and \\ \frac{-4+y_1}{2}=-6 \\ -4+y_1=-12 \\ y_1=-8 \end{gathered}\text{ Point B is }(-5,-8)

Answer:

Hence, (-5,-8) is point B.

Calculate the variance and the standard deviation of the data below 23. 19, 22, 30, 28
Alina [70]

To get the variance, start with finding the mean of your data points:

(23 + 19 + 22 + 30 + 28) / 5 = 24.4

Now take each data point and subtract the mean from it, then square that value:

23 - 24.4 = -1.4 * -1.4 = 1.96

19 - 24.4 = -5.4 * -5.4 = 29.16

22 - 24.4 = -2.4 * -2.4 = 5.76

30 - 24.4 = 5.6 * 5.6 = 31.36

28 - 24.4 = 3.6 * 3.6 = 12.96

Now get the average of those new numbers. That is your variance:

(1.96 + 29.16 + 5.76 + 31.36 + 12.96) / 5 = 16.24

The standard deviation will be the square root of the variance:

√(16.24) = 4.0299 (rounded to 4DP)

If AACD ~ AABE, find the value of x.
Anastaziya [24]

9514 1404 393

Answer:

  x = 16

Step-by-step explanation:

Corresponding sides are proportional.

  BE/CD = AE/AD

  20/(3x+8) = (x-1)/(x-1+27)

  20(x+26) = (3x+8)(x -1)

In standard form, this is ...

  3x^2 -15x -528 = 0

  x^2 -5x -176 = 0 . . . . . . divide by 3

  (x -16)(x +11) = 0 . . . . . . . factor

  x = 16

__

This is the positive value that makes the product zero. x=-11 will also make the product 0, but gives negative segment lengths in the geometry. It is an extraneous solution.
