Answer:

<h2>f( - 9) = 187</h2>

Step-by-step explanation:

f(x) =  {2x}^{2}  - 5x - 20

To find f(-9) , substitute the value of x that's -9 into f(x). That is for every x in f (x) replace it with - 9

We have

<h3>f( - 9)  = 2 ({ - 9})^{2}  - 5( - 9) - 20 \\  = 2(81) + 45 - 20 \\  = 162 + 25 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:</h3>

We have the final answer as

<h3>f( - 9) = 187</h3>

Hope this helps you

vladimir2022 [97]

Answer:

The answer is "Options A, B, and E represent mutually exclusive events".

Step-by-step explanation:

Two occurrences that can happen immediately called mutually incompatible. Let's now glance at our options and figure out where the statements are mutually incompatible events.

In Option A: You could see that landing on an unwanted portion and arriving on 2 are events that are locally incompatible, even as undesirable portion contains 3 and 4, and 2 were shaded.

In Option B: Arriving on a shaded part and falling on 3 are also mutually incompatible because there are 3 on a windows azure.

In Option C: A darkened portion and an increasing amount can land while 2 would be an even number as well as on the shaded portion. That number is very much the same.

In Option D: At the same time as 4 is greater than 3 and it is situated upon an undistressed section, landing and attracting a number larger than 3 can happen.

In Option E: Landing on a shaded part and landing on even a shaded part is an excluding event, since shaders may either be shaded or unlit.
