Mathematics

Answer:

Step-by-step explanation:

The average rate of change of function f on interval [a, b] is ...

m = (f(b) -f(a))/(b -a)

Here, that is ...

m = (f(6) -f(2))/(6 -2)

So, we need to evaluate the function at x=6 and x=2. Writing it in "Horner form" makes this easier.

f(x) = (x +3)x -2

f(6) = (6 +3)6 -2 = 54 -2 = 52

f(2) = (2 +3)2 -2 = 10 -2 = 8

Then the slope is ...

m = (52 -8)/4 = 13 -2 = 11

The average rate of change of f(x) from 2 to 6 is 11.

Compare and contrast the relative frequency for the whole table in part B with the two-way frequency table given in the activity

PIT_PIT [208]

The way to convert counts into relative frequencies in a Two Way Relative Frequency Table is to divide the count by the total number of items

<h3>What is a Frequency Table?</h3>

This refers to the depiction of the number of times in which an event occurs in the form of a table.

Hence, when a two-way frequency table is used, it shows the visual representation of the possible relationship between different sets of data.

Please note that your question is incomplete as you did not provide the frequency table needed and also the trends and generalizations to find, so a general overview was given.

At another sanctuary, the number of nesting turtles decreased by 10%. This year there were 234 nesting turtles. How many nesting

Alex

Answer:

260 nesting turtles were at this sanctuary last year

Step-by-step explanation:

Given:

The number of nesting turtles decreased = 10%

Number of turtles present in sanctuary this year = 234

To Find:

Number of nesting turtles present at this sanctuary last year= ?

Solution:

Let the number of nesting turtles present at this sanctuary last year be x

Then,

x- 10% of x = Number of turtles present in sanctuary this year

x- 10% of x = 234

$x- (\frac{10}{100} \times x) = 234$

$x- (\frac{1}{10} \times x) = 234$

$x- (\frac{x}{10}) = 234$

$\frac{10x-x}{10}=234$

$\frac{9x}{10}=234$

$9x=234\times 10$

$9x=2340$

$x=\frac{2340}{9}$

x= 260

Let Upper A equals left bracket Start 2 By 2 Matrix 1st Row 1st Column negative 2 2nd Column 4 2nd Row 1st Column 1 2nd Column 3

Yuliya22 [10]

Answer: a) AB = $\left[\begin{array}{ccc}-14&26\\-11&22\end{array}\right]$ ; b) $\left[\begin{array}{ccc}5&-5\\13&9\end{array}\right]$ ; c) No, they are different; d) No, they are never the same;

Step-by-step explanation:

a) A = $\left[\begin{array}{ccc}-2&4\\1&3\end{array}\right]$ , B = $\left[\begin{array}{ccc}-2&1\\-3&7\end{array}\right]$ . This multiplication is possible, because matrix A has 2 columns and matrix B has 2 rows. When those value are equal, the multiplication is possible.

AB = $\left[\begin{array}{ccc}-2&4\\1&3\end{array}\right]$ . $\left[\begin{array}{ccc}-2&1\\-3&7\end{array}\right]$ = $\left[\begin{array}{ccc}-14&26\\-11&22\end{array}\right]$

b) BA = $\left[\begin{array}{ccc}-2&1\\-3&7\end{array}\right]$ . $\left[\begin{array}{ccc}-2&4\\1&3\end{array}\right]$ = $\left[\begin{array}{ccc}5&-5\\13&9\end{array}\right]$

c) As, we can see, parts a and b are differents.

d) With matrices, multiplication is not commutative, which means AB≠BA
