inysia [295]

Answer:

Step-by-step explanation:

Given :

Stem Leaves

2 | 6, 7, 7

3 | 0, 2, 3, 3, 4.

4 | 0, 5

To Find: What is the range of the data in this stem-and-leaf plot?

Solution :

Since we are given key 3 vertical line 0 equals 30.

So, in the given stem leaf plot the number are :

26,27,27,30,32,33,33,34,40,45

Now Range = maximum number - minimum number

Range = 45-26

Range = 19

Hence The range of the data in this stem-and-leaf plot is 19

Answer:

81(x + 2y)(x - 2y)

Step-by-step explanation:

$81 {x}^{2} - 324 {y}^{2} \\ \\ = {(9x)}^{2} - {(18y)}^{2} \\ \\ = (9x + 18y)(9x - 18y) \\ \\ = 9(x + 2y) \times 9(x - 2y) \\ \\ = 81(x + 2y)(x - 2y)$

Given the function F (x) = x2 -2x -5 determine the average rate of change of the function over the interval -5 < x <6.

KengaRu [80]

Answer:

Step-by-step explanation:

Here f(x) = x^2 - 2x - 5, which at x - -5 is 25 +10 - 5 = 30 and at x = 6 is 19.

The average value of a function f(x) over an interval [a, b] is

f(b) - f(a)

ave. val. = ---------------

b - a

which in this particular case is

19 - 30

ave. val. = ----------------- = -11/11 = 1

6 - (-5)

The average value of this function f(x) = x^2 - 2x - 5 on [-5, 6] is 1.
