Answer choices: 0 1 -1 -2 ( chose this and got it wrong so it's not this)

Dmitry [639]

Use the formula for average rate of change over an interval of two points:

$\frac{y_2 - y_1}{x_2 - x_1}$

We have two points: (-2, -1) and (0, -1). Plug the values into the formula:

$\frac{-1 - (-1)}{0 - (-2)} = \frac{0}{2} = 0$

The average rate of change over the interval [-2,0] is 0.

PLEASE PLEASE HELP!!!!

Usimov [2.4K]

Answer:

Step-by-step explanation:

$\cos( \alpha ) + i\sin( \alpha ) = {e}^{i (\alpha + 2\pi)}$

z = 3(cos π/2 + i sin π/2) =→

$3 {e}^{i \frac{\pi}{2} }$

z⁷ =

${3}^{7} {e}^{i \frac{7\pi}{2} } = {3}^{7} {e}^{i \frac{(7 - 4)\pi}{2} } = {3}^{7} {e}^{i \frac{3\pi}{2} } = {3}^{7} ( \cos( \frac{3\pi}{2} ) + i \sin( \frac{3\pi}{2} ) ) = 2187( \cos( \frac{3\pi}{2} ) + i \sin( \frac{3\pi}{2} ) )$

What is the net change in how many bags are on the shelf from

Temka [501]

Answer:

-2

Step-by-step explanation:

The computation of net change from the beginning of Tuesday to the end of Monday is shown below:-

The change at the last of Tuesday

Change = Restock - Sales

= 6 - 5

= 1

Here it indicates that the number of bags is rise by 1

The change at the last of Wednesday

Change = Restock - Sales

= 12 - 8

= 4

Here it indicates that the number of bags is rise by 4

The change at the last of Thursday

Change = Restock - Sales

= 12 - 2

= 10

Here it indicates that the number of bags is rise by 10

The change at the last of Friday

Change = Restock - Sales

= 18 - 19

= -1

Here it indicates that the number of bags is fall by -1

The change at the last of Saturday

Change = Restock - Sales

= 24 - 22

= 2

Here it indicates that the number of bags is rise by 2

The change at the last of Sunday

Change = Restock - Sales

= 0 - 15

= -15

Here it indicates that the number of bags is fall by -15

The change at the last of Monday

Change = Restock - Sales

= 0 - 3

= -3

Here it indicates that the number of bags is fall by -3

According to the given situation, it is equivalent the algebraic sum of every change

So,

Net change = 1 + 4 + 10 + (-1) + 2 + (-15) + (-3)

Using associative property: (1 + 4 + 10 + 2) - (1 + 15 +3)

Simplifying: 17 - 19 = -2
