16^3 - 8^3

Take out 8^3 as a common factor.

16^3 = 2^3 * 8^3

8^3(2^3 - 1)  

8^3(8 - 1) = 8^3 * 7

(4^3 + 2^3)     Expand

64 + 8            Combine

72

72 = 9 * 8

Conclusion

(8*3 * 7 )(9*8)

7*9 = 63

So any number containing 63 will divide into the reduced form of

(16^3–8^3)(4^3 +2^3)

The correct set notation for the domain of the function is {x | x ∈ R, x ≠ 3}. Option {x | x ∈ R, x ≠ 3} is the correct answer.

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

In this case, the given function is:

F(x) = (x - 4)/(x - 3)

The function is defined for all real numbers (x ∈ R) except when the denominator (x - 3) becomes zero, as division by zero is undefined.

Therefore, we need to find the value of x that makes the denominator zero and exclude that value from the domain.

The denominator becomes zero when:

x - 3 = 0

x = 3

So, the domain of the function is {x | x ∈ R, x ≠ 3}. This set notation means that the function is defined for all real numbers except x = 3. Thus, the correct set notation for the domain of the function is {x | x ∈ R, x ≠ 3}. Option {x | x ∈ R, x ≠ 3} is the correct answer.

Answer:

y=5x-5

Step-by-step explanation:

The slope of the graph is 5 and the Y intercept is (0,-5). Plug into slope intercept form : y=mx+b to get the equation.

Applying the chord theorem, since chords RS and TU are equal, then the measure of arc RS is: 106°.

The chord theorem states that if two chords in a circle are equal in length, then their corresponding minor arcs will also be equal in measure.

Since chords RS = TU, therefore:

m(RS) = m(TU)

Substitute

8x - 14 = 7x + 1

8x - 7x = 14 + 1

x = 15

m(RS) = 8x - 14

Plug in the value of x

m(RS) = 8(15) - 14

m(RS) = 106°

Hence, 440 cupcakes were sold on that day.

The bakery sold a total of 400 cupcakes that day, with 224 of them being chocolate cupcakes, representing 56 precent of the total.

Use the concept of percentage defined as:

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred.

Given that,

A bakery sold 224 chocolate cupcakes in a day.

The 224 chocolate cupcakes represent 56% of the total number of cupcakes sold that day.

To find the total number of cupcakes sold,

Use the percentage given and some simple math.

If 56% of the cupcakes sold were chocolate cupcakes and that amounts to 224 cupcakes,

Set up the following equation:

0.56 x Total number of cupcakes = 224 cupcakes

To find the total number of cupcakes,

Divide both sides of the equation by 0.56:

Total number of cupcakes = 224 cupcakes / 0.56

Calculating this,

The bakery sold a total of 400 cupcakes that day.

Answer:

14%

Step-by-step explanation:

946/1100 = 0.86

1 - 0.86 = 0.14 = 14%

Answer: 14%

Answer:

14% decrease

Step-by-step explanation:

Percentage Decrease = [ (Starting Value - Final Value) / |Starting Value| ] × 100

Percentage Decrease = [ (1100 - 946) / |1100| ] × 100

Percentage Decrease = [ (154) / |1100| ] × 100

Percentage Decrease = [ 0.14] × 100

Answer:

  cos(Θ + 2π) + cos(Θ + 4π) = -0.2

Step-by-step explanation:

The cosine funciton is periodic with period 2π, so we have ...

  cos(Θ) = cos(Θ + 2π) = cos(Θ + 4π) = -0.1

__

The sum is ...

  cos (Θ + 2π) + cos(Θ + 4π) = -0.1 +(-0.1) = -0.2

Answer:

  B.  x = 1, y = 0, z = 3

Step-by-step explanation:

Systems of linear equations are readily solved by a suitable calculator or spreadsheet. The attached calculator display shows the solution to be ...

  x = 1, y = 0, z = 3

__

There are several ways a calculator can solve these equations. The method shown here is to input the equations as an augmented matrix of their coefficients, and reduce it to row-echelon form. The right-most column of the reduced matrix is the set of variable values in the same order as the coefficients.

A graphing calculator can also be used to graph the equations. You may have to write one variable in terms of the others. (Here, it is convenient to let z=3-y.) The second attachment shows the solution (x, y) = (1, 0). This is sufficient to choose the correct answer. Or, you can finish the solution by substituting into the expression for z: z = 3 -y = 3 -0 = 3.

Many calculators will solve the system of equations after you enter it as presented in the problem statement.

Answer:

  (d)  240/289

Step-by-step explanation:

The trig identity for the sine of a double angle can be used to find the desired value.

  sin(2θ) = 2sin(θ)cos(θ)

__

The cosine of this 3rd-quadrant angle is negative:

  cos(θ) = -√(1 -(-8/17)²) = -(√(289 -64))/17 = -15/17

Then the desired sine value is ...

  sin(2θ) = 2(-8/17)(-15/17) = 240/289

_____

Additional comment

The attached calculator result comes from the principal value of the arcsine function resulting in a 4th-quadrant angle for negative sine values. Double that angle will still be a 4th-quadrant angle. When the translation is made to the appropriate quadrant, the desired double angle will be a 1st-quadrant angle with a positive sine.

Answer:

x + (5x-9)

Step-by-step explanation:

x stands for the number of coins Nancy has

Kevin has 9 less than 5 times what Nancy has, so his part of the expression is 5x-9

To find the total number of coins they have, you have to add Nancy's number of coins x plus Kevin's number of coins 5x-9

x + (5x-9)

But you have to put parentheses around Kevin's 5x-9 so that part of the expression is calculated first, as per order of operations

Answer:

The reasoning of Jamie is incorrect

Step-by-step explanation:

No, because in the expression 4(x+1)  you will first need to multiply 4 by x, your result is 4x, and then you multiply 4 by 1, you get 4, so the answer will be 4x+4, as mentioned up in the problem.

Also in the expression 6x-2x+4  ,you will first need to subtract 2x from  6x, your result is 4x ,and then you add 4 , so the answer will be 4x + 4

Finally,we obtain

6x-2x+4 = 4x + 4 and 4(x+1) = 4x + 4

Conclusion:

The reasoning of Jamie is NOT correct.

Answer:

Np Jamie is wrong

Step-by-step explanation:

No, because in the phrase 4(x+1), you must first multiply 4 by x, which gives you 4x, and then multiply 4 by 1 to get 4, giving you 4x+4, also, in the phrase 6x-2x+4, you must subtract 2x from 6x to get 4x, and then add 4 to get 4x + 4x.

Our final solution is:

4(x+1) = 4x + 4 and 6x-2x+4 = 4x + 4

Answer:

Step-by-step explanation:

[tex]3*(7+2)/\sqrt{4}[/tex]

You use PEDMAS - priority of calculation

1) Paranthesis

2) Exponents

3) Divide or Multiple (whichever comes first, reading left to right)

4) Add or Subtract (whichever comes first, reading left to right)

so,

Parenthesis first:

[tex]7+2=9[/tex]

becomes

[tex]3*9/\sqrt{4}[/tex]

No exponents, so we skip this step

Left to right for multiply or divide: first comes multiply.

[tex]3*9 = 27[/tex]

becomes

[tex]27/\sqrt{4}[/tex]

Now, last one is divide:

[tex]27/\sqrt{4} = 27/2 = 13.5[/tex]

Answer:

C. √147

Step-by-step explanation:

Set the values of the triangle up in the Pythagorean Theorem.

a² + b² = c²

x² + 7² = 14²

Take 7 and 14 to the power of 2.

x² + 49 = 196

Subtract 49 from both sides.

x² = 147

Take the square root of both sides. There will only be one answer since lengths cannot be negative.

x = √147

Answer:

C

Step-by-step explanation:

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 7² = 14²

x² + 49 = 196 ( subtract 49 from both sides )

x² = 147 ( take square root of both sides )

x = [tex]\sqrt{147}[/tex]
