The graph of a function f is shown. Use the graph to estimate the average rate of change from x = –2 to x = 0

Mathematics

vodomira [7]3 years ago
4 0

Answer:

Average rate of change = 2

Step-by-step explanation:

Formula to get the rate of change of a function between x = b and x = a is,

Rate of change = \frac{f(b)-f(a)}{b-a}

We have to calculate the average rate of change between x = -2 and x = 0

From the graph attached,

At x = -2,

f(-2) = 0

At x = 0,

f(0) = 4

Therefore, average rate of change = \frac{f(0)-f(-2)}{0-(-2)}

                                                          = \frac{4-0}{2}

                                                          = 2

Average rate of change of the given function between x = -2 and x = 0 is 2.

zlopas [31]

Answer:

The answer is "0.00088"

Step-by-step explanation:

Many ways of selecting r articles of n,\to ^nC_r = \frac{n!}{(r! \times (n-r)!)}

P(wins the player) = \frac{1}{\text{Any combinations of possible numbers}}

= \frac{1}{^{20} C_3}\\\\

= \frac{1}{\frac{20!}{(3!\times 17!)}}\\\\= \frac{1}{1140}\\\\= 0.00088

Which of the following represents the mean absolute deviation of Jamal’s data?
Gnesinka [82]

Answer:

1.178

Step-by-step explanation:

(for Jamal)

5 x 2 = 10

6 x 3 = 18

7 x 2 = 14

8 x 1 = 8

10 x 1 = 10

Mean: 10 + 18 + 14 + 8 + 10 = 60/9 = 6.6

6.6 - 5 = 1.6 x 2 = 3.2

6.6 - 6 = 0.6 x 3 = 1.8

7 - 6.6 = 0.4 x 2 = 0.8

8 - 6.6 = 1.4

10 - 6.6 = 3.4

<em>Mean Absolute Deviation:</em> 3.2 + 1.8 + 0.8 + 1.4 + 3.4 = 10.6/9 = 1.178

The slope of a line is 10/7. what is the slope of a line perpendicular to this line?​
viktelen [127]
<h3>Answer:  -7/10</h3>

Explanation:

The perpendicular slope is the negative reciprocal of the original. That means you flip the fraction to get from 10/7 to 7/10, then you flip the sign from positive to negative, going from 7/10 to -7/10.

Your math teacher or textbook may use the phrasing "flip the fraction and flip the sign" as a way to help you remember.

Note how 10/7 times -7/10 is equal to -1. This applies to any pair of perpendicular slopes as long as neither line is vertical.
