Find f(-9) when f(x) = |x|- 6.

Answers

Answer: f(x) = 3

Step-by-step explanation:

f(x) = |-9| - 6

f(x) = 9 - 6

f(x) = 3

Answer:

Step-by-step explanation:

F(x)= f(-9) meaning x is -9.

When -9 is in absolute value is negative it turns into positive because anytime it it absolute it will turn any number postitive. so the equation turns into 9-6=f(x) which is 3.

There were twelve times more children than adults at the matinee performance of the school play. There were 455 people at the play. How many adults and children were there?

Answers

Answer:

35 adults, 420 children

Step-by-step explanation:

1. Set up variables

Let's say children is c and adults is a.

2. Create the equations

c = 12a AND c + a = 455

3. Plug in the variables

Let's take c = 12a and substitute it in for c in the equation "c + a = 455." That would be...

12a + a = 455

13a = 455

a = 35

3. Plug in more variables

Now we have our answer for a, so let's plug it into the other equation. That would be...

c + a = 455

c + 35 = 455

c = 420

can someone please explain the equation I am supposed to use

Answer:

MLN1 : 3

Step-by-step explanation:

There are several ways you can go at this. Perhaps the most complicated is using the distance formula to determine the various ratios. Since all of the points are on the same line segment, I find it easier just to consider the x-coordinate differences. (The length of PQ is Q - P for the purposes here.)

For x-coordinates only, ...

L -A = -1 -(-3) = 2

M -A = 0 -(-3) = 3

N -A = 1 -(-3) = 4

Z -A = 3 -(-3) = 6

Note that the corresponding distances from Z are ...

Z -L = 3 -(-1) = 4

Z -M = 3 -0 = 3

Z -N = 3 -1 = 2

Then the ratios are ...

AL : LZ = 2 : 4 = 1 : 2 . . . . . partitioning by point L

AM : MZ = 3 : 3 = 1 : 1 . . . . partitioning by point M

AN : NZ = 4 : 2 = 2 : 1 . . . . partitioning by point N

AL : AZ = 2 : 6 = 1 : 3 . . . . partitioning by L expressed differently

Now we have what we need to answer the questions.

Point M partitions into 1 : 1

Point L partitions into 1 : 2

Point N partitions into 2 : 1

AL : AZ = 1 : 3

The amplitude is 2.

_____

* There is no general agreement as to how to compute the amplitude when the wave is asymmetrical. Some authors use the same formula. Some consider the amplitude to be the maximum deviation from average. Some define only a "peak-to-peak" amplitude in those cases. The meaning of "amplitude" in those cases depends on the context in which the question is asked.

Multiplying Exponential Expressions:

1.1 Multiply (2x+3) by (2x+3)

The rule says : To multiply exponential expressions which have the same base, add up their exponents.

In our case, the common base is (2x+3) and the exponents are :

1 , as (2x+3) is the same number as (2x+3)1

and 1 , as (2x+3) is the same number as (2x+3)1

The product is therefore, (2x+3)(1+1) = (2x+3)2

What is the pressure in atmospheres exerted by a 0.500 mole sample of nitrogen gas in a 10.0 L container at 25.0°C?

Answers

Answer:

1.2218 atm

Step-by-step explanation:

From ideal gas formula,

PV=nRT

Where n= number of moles

V= volume

T= temperature=25.0°C

= (273 + 25) = 298 K

R= gas constant = 0.082 l atm /K mol.

Making P subject of formula we have

P= [nRT] /V

Then substitute the values we have

P= [0.5 x 0.082 x 298] / 10

P= 1.2218 atm
