Find the GCF of 12x^2y and 27xy^3z

Check the picture below.

bearing in mind that ⌈some expression⌉ means "ceil" or the ceil() function, which means any number in between one integer and the next, "ceils" or gets bumped up to the next integer.

namely for example, for y = ⌈x⌉ will yield

y(0.5) = 1

y(0.7) = 1

y(0.0000001) = 1

y(3.0000001) = 4

y(-2.000001) = -2

y(-5.00001) = -5

and so on

the same is true btw for the y = ⌊x⌋ or the "floor" floor() function, but it "floors" or drops down instead.

y(0.5) = 0

y(3.9999999) = 3

y(-5.0000001) = -6

and so on.

in this case is y = 4⌈x⌉, so any values in between each integer for "x" gets bumped up.

Answer:

Step-by-step explanation:

1. f(x) < 0

Interval of the domain where the graph is below the x-axis

because the negative regions of a function compromises those intervals where the function lies below the x-axis

2. x-intercept

Location on graph where output is zero

because when we find x-intercept we put y=0

3. y-intercept

Location on graph where input is zero

because when we find y-intercept we put x=0

4. f(x) > 0

Interval of the domain where the graph is above the x-axis

because the positive regions of a function compromises those intervals where the function lies above the x-axis

ANSWER

[tex](4 + 9i)(7 - 4i) = 64 + 47i [/tex]

EXPLANATION

The given complex number expression is:

[tex](4 + 9i)(7 - 4i)[/tex]

We expand using the distributive property to get;

[tex](4 + 9i)(7 - 4i) = 4(7 - 4i) + 9i(7 - 4i)[/tex]

[tex](4 + 9i)(7 - 4i) = 28- 16i + 63i - 36 {i}^{2} [/tex]

Recall that,

[tex] {i}^{2} = - 1[/tex]

Our expression now simplifies to:

[tex](4 + 9i)(7 - 4i) = 28 + 47i + 36 [/tex]

[tex](4 + 9i)(7 - 4i) = 64 + 47i [/tex]

Answer: [tex]64+47i[/tex]

Step-by-step explanation:

Given the Complex numbers multiplication:

[tex](4+9i)(7-4i)[/tex]

You need to follow these steps:

1. Apply Distributive property:

[tex](4+9i)(7-4i)=(4)(7)+(4)(-4i)+(9i)(7)+(9i)(-4i)=28-16i+63i-36i^2[/tex]

2. You need to remember that:

[tex]i=\sqrt{-1}\\\\i^2=-1[/tex]

Then, you need to substitute [tex]i^2=-1[/tex]:

 [tex]28-16i+63i-36(-1)=28-16i+63i+36[/tex]

3. Finally, add the like terms:

By factorising a function, you can find the value of x-intercepts by substituting f(x)=0

By plotting a graph, you can check the values of x-intercepts

A function graph can be used to verify if a function is factored correctly by comparing the x-intercepts on the graph to the solutions of the factored function.

A function graph can be used to help verify that a function is factored correctly by examining its x-intercepts. When a function is factored correctly, the x-intercepts represent the values of x for which the function equals zero. In other words, they are the solutions to the equation f(x) = 0. By plotting the function and identifying the x-intercepts on the graph, we can compare them to the solutions of the factored function to determine if they match.

For example, let's say we have a function f(x) = (x+2)(x-3). The factored form suggests that the x-intercepts should occur at x = -2 and x = 3. By graphing the function and observing where it crosses the x-axis, we can confirm if these values are indeed the x-intercepts.

If the x-intercepts on the graph match the solutions of the factored function, it indicates that the function is correctly factored. However, if they do not match, it suggests an error in the factoring process.

Given the expression [tex]\frac{4x^4y^3}{-8x^2y }[/tex] you  need to remember a property called "Quotient of powers property". This property states the following:

[tex]\frac{a^m}{a^n}=a^{(m-n)}[/tex]

Therefore, in order to reduce the given expression to lowest terms, it is necessary to apply this property. Once you apply it, you get:

Step-by-step explanation:

let w be the cost of a bottle of water and p be the cost of a bag of pretzels

"2 bottles of water and 3 bags of pretzels is $7.05" can be written as

2w + 3p = 7.05    ------------- eq.1

"The cost of a bag of pretzels is $1.35" can be written as

p = 1.35 ------------- eq 2

Together, eq 1 and eq 2 make up your system of equations

To solve, take eq 2 and substitute this value int eq 1

2w + 3 (1.35) = 7.05

2w + 4.05 = 7.05

2w = 7.05 - 4.05

2w = 3

w = 1.5

Hence the cost of a bottle of water is $1.50

Answer: the cost of one bottle of water is $1.5 and the cost of one bag of pretzels is $1.35.

Step-by-step explanation: Let's call "b" the cost of a bottle of water and "p" the cost of a bag of pretzels, in the first equation of the system, we need to express the total prize of 2 bottles of water and 3 bags of pretzels, so it would be:

2b+3p=$7.05

The second equation will express the cost of a bag of pretzels:

p=$1.35

Now, to solve the system we replace the second equation into the first one:

2b+3($1.35)=$7.05

2b=$7.05-$4.05

2b=$3

b=$1.5

So the cost of one bottle of water is $1.5 and the cost of one bag of pretzels is $1.35.

Perimeter=120

ED=x (length)

FE=4x (breadth)

Perimeter of rectangle= 2(l+b)

Given,

2(x+4x)=120

2x+8x=120

10x=120

x=120÷10

x=12

Therefore, value of x is 12

Answer: 12

Step-by-step explanation:

You are given that perimeter = 120, length (FE) = 4x, and width (ED) = x

 P  =    2L  + 2w    (P = perimeter, L = length, w = width)

120 = 2(4x) + 2(x)

Answer:

x-axis only.

Step-by-step explanation:

2x = 5y2 - 3

Convert to vertex form:

x = 5/2 y^2 - 3/2

This is a parabola  with axis of symmetry  y = 0. The vertex is at (-3/2, 0) and it opens to the right.

The axis of symmetry is the x-axis ( y = 0).

The equation 2x = 5y2 - 3 is only symmetric with respect to the x-axis but not the y-axis or the origin.

To test an equation for symmetry with respect to the x-axis, you would replace 'y' with '-y' and see if the equation remains the same. For symmetry with respect to the y-axis, you'd replace 'x' with '-x'. For origin symmetry, you would replace 'x' with '-x' and 'y' with '-y'

Applying this to your equation, 2x = 5y2 - 3:

Answer:

5.6

Step-by-step explanation:

If there is 70 percent of chocolate milk in the fridge and she holds 0.125 in each canister and divide and get 5.6 then turn that back into a fraction which should be easy.

Ana can fill exactly 5 full glasses of chocolate milk with her 7/10 of a liter, as each glass holds 1/8 of a liter. The calculation involves simple fraction division and the realization that 56/10 simplifies to 5 3/5, indicating the number of full glasses.

The question is about determining how many glasses of chocolate milk Ana can fill from the amount she has in her refrigerator. Since each glass holds 1/8 of a liter and Ana has 7/10 of a liter of chocolate milk, we need to calculate how many 1/8 liter portions make up 7/10 of a liter. To find this, we can set up a division:

[tex]\(\frac{7/10}{1/8}\)[/tex].

To divide fractions, we multiply by the reciprocal of the divisor:

[tex]\(\frac{7/10}{1} \times \frac{8}{1}\) = \(\frac{56}{10}\).[/tex]

Now we simplify the resulting fraction:

[tex]\(\frac{56}{10}\)[/tex] simplifies to [tex]\(5 \frac{3}{5}\)[/tex].

So, Ana can fill 5 full glasses of chocolate milk and will have some milk left over.

Answer:

Events D and C are mutually exclusive.

Step-by-step explanation:

Two events D and C are mutually exclusive if

[tex]Pr(D\cup C)=Pr(D)+Pr(C)[/tex]

Find these probabilities. In a standard deck of 52 playing cards there are 13 diamond cards and 13 club cards.

The probabilty of chosing diamond is

[tex]Pr(D)=\dfrac{13}{52}=\dfrac{1}{4}[/tex]

The probabilty of chosing club is

[tex]Pr(C)=\dfrac{13}{52}=\dfrac{1}{4}[/tex]

The probabilty of chosing diamond or club is

[tex]Pr(D\cup C)=\dfrac{13+13}{52}=\dfrac{1}{2}[/tex]

Since

[tex]\dfrac{1}{2}=\dfrac{1}{4}+\dfrac{1}{4},[/tex]

events D and C are mutually exclusive.

Final answer:

In the context of a standard deck of 52 playing cards, the events representing diamonds (D) and clubs (C) are mutually exclusive events because a single card cannot be both a diamond and a club at the same time.

Explanation:

The question asks about the concept of mutually exclusive events in probability, using the context of a standard deck of playing cards. In a standard deck, there are four suits: spades, hearts, diamonds, and clubs. Diamonds (D) and clubs (C) are two different suits of cards, and so they are mutually exclusive events because the same card cannot be both a diamond and a club at the same time.

In reference to a standard deck of 52 cards which contains clubs, diamonds, hearts, and spades, each suit has 13 cards - A (ace), 2 through 10, J (jack), Q (queen), and K (king). Therefore, seeing as how a card from a deck cannot belong to two different suits, D and C are mutually exclusive events; there is no overlap between these two groups of cards.
