Answer:

Option D. 13122 is the answer.

Step-by-step explanation:

As we can see from the table having interval and average rate of change, figures under average rate of change are forming a geometric sequence.

Sequence is 2, 6, 18 , 54, 162, 486.

and we have to find the average rate of change from x = 8 to x = 9, means we have to find 9th term of the given sequence.

Now we know that explicit formula of the sequence can be written as T_{n}=ar^{n-1}

where Tn is the nth term of the sequence.

a = first term

r = common ratio

n = number of the term

Now from this explicit formula we can find the 9th term of the sequence.

From the given table

a = 2, r = 3, n = 9

T_{9}=2.3^{9-1}=2.3^{8}

T9 = 13122

Therefore Option D. 13122 will be the answer.

Find the given elements of matrix D<br> Please help!!!
TEA [102]

Answer:

Element wise subtraction.

Step-by-step explanation:

Matrix Subtraction is done element wise.

Therefore, D = \[  \left[ {\begin{array}{ccc}   3 & 1 & 0 \\   -1 & 2 & 4 \\9 & 7 & -2  \end{array} } \right]\] - \[  \left[ {\begin{array}{ccc}   5 & 2 & -4\\   1 & 12 & 3 \\ 11 & 3 & -2  \end{array} } \right]\]

This becomes:

\[   D =  \left[ {\begin{array}{ccc}   -2 & -1 & 4 \\    -2 & -10 & 1 \\    -2 & 4 & 0  \end{array} } \right]\]

Now, $ d_{11} = -2 $

$ d_{12} = -1 $

$ d_{13} = 4 $

$ d_{21} = -2 $

$ d_{22} =  -10 $

$ d_{31} = -2 $

Pavel [41]

Answer:

1^x-2

Step-by-step explanation:

First you put log(10)^x into the calculator, the product is 1^x. Then you subtract that by log(10)^3 which you you get 1^x-1 then you subtract that answer by 1 to get 1^x-2.

The following are the temperatures of 10 days in winter in °C. − 3 , 0 , 10 , 2 , 8 , − 5 , − 1 , 9 , 2 , − 3 Work out the mean
marissa [1.9K]

The mean temperature of the given data − 3 , 0 , 10 , 2 , 8 , − 5 , − 1 , 9 , 2 , − 3 is 1.9

mean= 1.9

<h3>What is mean of the data?</h3>

The mean, or average, is calculated by adding up the data and dividing by total number of data.

Given data: − 3 , 0 , 10 , 2 , 8 , − 5 , − 1 , 9 , 2 , − 3

Now, mean =   \frac{sum \;of\; observation}{Total \;number \;of \;observation}

mean = \frac{(-3)+ 0+10+2+8+(-5)+ (-1)+ 9+2+(-3)}{10}

           = \frac{19}{10}

mean= 1.9

Hence, the mean of − 3 , 0 , 10 , 2 , 8 , − 5 , − 1 , 9 , 2 , − 3  is 1.9
