Simplify each expression.
(-3)¹/₃ . (-3)¹/₃ . (-3)¹/₃

Answer:

(a + b) = 9

Step-by-step explanation:

The a² - b² formula is also known as "the difference of squares formula"

It can be decomposed as follows:
a² - b²  = (a - b)(a + b)

Since we are given a + b = 5 and a² - b² = 45

we have

45 = 5 (a + b)

Dividing by 5 both sides
45/5 = (a + b)

9 = (a + b)

or,

(a + b) = 9

a) The Linear equation is,

y = 13.5x + 119.5

b) The annual membership fee at this club is $119.5.

c) The fee that is charged each time a member plays racquetball is $13.5.

What is Linear equation?

The linear equation of a line with slope m is defined as;

y = mx + b

Now, Let the linear equation is;

y = mx + b

For, Jay played racquetball 77 times and payed a total of $1159.

1159 = 77m + b  .... (i)

And, For Sammy played racquetball 37 times and payed a total of $619.

619 = 37m + b ... (ii)

Solve both equation as;

1159 - 619 = 77m - 37m

40 m = 540

m = 13.5

And, b = 119.5

Hence, The Linear equation is,

y = 13.5x + 119.5

So, The annual membership fee at this club is $119.5

The fee that is charged each time a member plays racquetball is $13.5.

Hence,

a) The Linear equation is,

y = 13.5x + 119.5

b) The annual membership fee at this club is $119.5.

c) The fee that is charged each time a member plays racquetball is $13.5.

Answer:

It is 6×x 6x-18=45

6x=45-18

=27

6x=27

27 divided by 6 = 4.5

Using the Pythagorean Theorem, the values of x are given as follows:

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:

[tex]h^2 = l_1^2 + l_2^2[/tex]

Hence, in the first triangle:

x² + 35² = 37²

x² = 37² - 35²

x² = 144

x = sqrt(144)

x = 12.

On the second triangle, we have two right triangles, hence:

x = a + b.

a² + 8² = 10²

a² = 36

a = sqrt(36)

a = 6.

b² + 8² = 17²

b² = 225

b = sqrt(225)

b = 15.

Hence the value of x is given as follows:

x = a + b = 6 + 15 = 21.

The equation setup up to solve for x is 2( 4x + 2 ) = 40 and the numerical value of x is 4.5.

A bisector divides segments or angles into two equal halves.

Given the data in the question;

Since AC is bisected at point E and we know that a bisector divides segments or angles into two equal halves.

AC = 2 × AE

Hence

40 = 2( 4x + 2 )

Rewrite the equation such that x will be at the left side.

2( 4x + 2 ) = 40

To solve for x, remove the parenthesis using distributive property.

2( 4x + 2 ) = 40

2×4x + 2×2 = 40

Rewrite the equation such that x will be at the left side.

8x + 4 = 40

Subtract 4 from both sides.

8x + 4 - 4 = 40 - 4

8x = 36

Divide both sides by 8

8x/8 = 36/8

x = 36/8

x = 4.5

Therefore, the equation setup up to solve for x is 2( 4x + 2 ) = 40 and the numerical value of x is 4.5.

The profit for 33 sales is $145

An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.

Given:

f(x) = 5x is the  revenue (in dollars) for selling x hamburgers.

profit = $20 less than revenue

So, the equation for the profit is

profit = 5x - 20

Now, if sales is 33 i.e., x=33 then profit will be

profit = 5(33) - 20

profit = 165-20

profit = $145

If three integers have a mean of 9, a median of 12, and a range of 13, then the three integers are 1, 12, and 14.

As the median is the value that's exactly in the center of a set of values, one of the three integers is 12.

Considering the first and third integers to be x and y, the range can be given as

x - y = 13

x = 13 + y

As mean can be given as,

x + 12 + y / 3 = 9

Putting x = 13 + y in this equation,

13 + y + 12 + y / 3 = 9

25 + 2y = 9 × 3

25 + 2y = 27

2y = 27 - 25

2y = 2

y = 2/2

y = 1

As,

x = 13 + y

x = 13 + 1

x = 14

Hence the three integers are calculated to be 1, 12, and 14.

The measure of the angles are  ∠A = 33°  ,   ∠B = 33° and   ∠C = 114°

Supplementary angles are the angles whose sum is equal to [tex]180^{o}[/tex].

According to the question we have been given that the three angles that is ∠A , ∠B and ∠C are the supplementary angles that is their sum is 180°.

Let the measure of ∠A = x = ∠B

and the measure of ∠C = 81 + x

Now,

      ∠A + ∠B + ∠C = 180°

Putting the required values we get

        x° + x° + (81 +x )° = 180°

        2x° + 81° + x° = 180°

             3x° = 99°

               x° = 33°

Along with the question statement, we are provided with a reference attachment, which is a grid, consisting of two graphs, and the equation of the parent graph is [f(x) = |x|].

We are required to calculate the equation of the other graph, which is a translated version of the parent graph.

From the reference grid, we can clearly see that, the vertex of the parent graph is at the origin (0, 0) while that of the translated graph is at (-2, 1), i.e., the vertex translated by 2 units to the left along the x-axis and then, 1 unit upwards along the y-axis. And this translation will be followed by every point of the daughter graph.

Hence, the equation of the translated graph will be [f(x) = (|x-2| + 1)].

Step-by-step explanation:

(f o g)(x) is found by replacing the x in f(x) by g(x).

= 4(2x^2 + 3) + 1

= 8x^2 + 12 + 1

= 8x^2 + 13.

Step-by-step explanation:

let's write it a little bit nicer

5.7 + 67v = -9.3 + 65v | subtract 65v on both sides

5.7 + 2v = -9.3 | subtract 5.7 on both sides

2v = -9.3 - 5.7 = -15 | divide both sides by 2

v = -7.5

Solve for x by factoring. Obtain the roots of the expression. Solve the quadratic form and obtain the complex solutions. Equate the expression to zero and divide by the common factor 4, and factor out x.

4x^3-8x^2+16x

4x^3-8x^2+16x = 0

x(x^2-2x+4) = 0

x =0

x^2-2x+4 = 0

by quadratic formula,

x =  (-b±√(b²-4ac))/(2a)

x= (--2±√((-2)²-4(1x4))/(2)

x =  (2±√(4-16))/(2)

x =  (2±√-12)/(2)

Let √-12 = i , a complex root

x =   (2±i)/(2)

x =  (2+i)/(2)

x =  (2-i)/(2)

x = 0

x =  (2+i)/(2)

x =  (2-i)/(2)
