Find the multiplicative inverse of
[tex] \frac{ - 4}{9} + ( \frac{2}{5} + \frac{3}{8} )[/tex]
​

The best answer to the given question is B.

When a variable "varies inversely as y," it means that as y increases, the variable decreases, and vice versa. This relationship is expressed mathematically as:

variable = k/y

where k is a constant.

When a variable "varies directly as y," it means that as y increases, the variable also increases, and vice versa. This relationship is expressed mathematically as:

variable = k*y

where k is a constant.

Option (a) does not provide any information about the relationship between variables. Option (c) and (d) provide incomplete information as they do not specify the variable that varies with y. Option (b) correctly explains the two types of relationships between variables and their mathematical expressions.

Option B is the best answer.

College = $12,000

Gifts = $1,000

Vacations = $1,500

Clothes = $800

Charity =$600

Total monthly expenses = $21,840

Total annual expenses = $37,740

Average monthly expenses = $3,135 ($37,740 ÷ 12)

Monthly Income = $1,600

Yearly Income = $ 19,200 ($1,600 x 12)

Annual Scholarship = $3,000

Total annual income = $22,200

Average monthly income = $1,850 ($22,200 ÷ 12)

Average monthly income = $1,850

The expression (7√98 + 3√242) divided by 6√50 simplifies to the fraction of 4/3.

To simplify the expression (7√98 + 3√242) ÷ 6√50, we need to rationalize the denominator. This means we need to simplify the expression in such a way that there are no radical signs in the denominator. To do this, we can use the fact that the product of a radical and its conjugate is a rational number.

First, let's simplify the terms under the radicals by factoring out the perfect squares:

√98 = √(49*2) = 7√2

√242 = √(121*2) = 11√2

Now the expression becomes:

(7√2 + 311√2) ÷ (6√(252))

= (7√2 + 33√2) ÷ (6*5√2)

= 40√2 ÷ 30√2

= 4/3

In conclusion, to simplify expressions involving radicals, we need to factor out perfect squares and use the property of the conjugate to rationalize the denominator.

Answer:

C. complementary

Michel-Eugène Chevreul discovered that placing complementary colors next to each other can create the greatest contrast and vibrancy in color perception. This is because complementary colors are located opposite each other on the color wheel and, when placed side by side, they enhance each other and create a strong visual impact. For example, placing yellow next to violet or blue next to orange can create a dynamic and eye-catching effect. In contrast, placing tertiary colors (colors made by mixing primary and secondary colors) or arbitrary colors next to each other may not create as much contrast or visual interest. Overall, understanding color theory and the relationships between different colors can be helpful for creating visually appealing designs, artworks, or other color-based projects.

The total cost paid on the condominium is $468,046.80.

The total cost means total expenditure incurred to produce some type of output.  The total cost is calculated as follows:

The total number of monthly payments is:

= 30 years x 12 months/year

= 360 months

The total amount paid towards mortgage is:

= 360 x $1175.13

= $423,046.80

The total cost of the condominium will be:

= Down payment + Total amount paid towards mortgage

= $45,000  + $423,046.80

C is the correct answer.

If company's marginal cost function is c(x)= 14 / √x, the total cost of producing the first 25 units is $10.67.

The marginal cost function is given as c(x) = 14 / √x, where x is the number of units produced.

To find the total cost of producing the first 25 units, we need to integrate the marginal cost function from x=0 to x=25, as follows:

Total cost = ∫₀²⁵ 14 / √x dx

We can use integration by substitution to solve this integral. Let u = √x, then du/dx = 1/(2√x), and dx = 2u du. Substituting these into the integral, we get:

Total cost = ∫₀⁵ √14/u du

This can be integrated using the power rule of integration. We have:

Total cost = 2√14 [[tex]u^{(3/2)[/tex]/3]₀⁵

Substituting back u = √x, we get:

Total cost = 2√14 [[tex](\sqrt{x})^{(3/2)[/tex]/3]₀²⁵

= 2√14 [[tex](\sqrt{25})^{(3/2)[/tex]/3 - [tex](\sqrt{0})^{(3/2)[/tex]/3]

(7.5, -9) is the final value after reflection and dilation.

To reflect a vector across the line y=x, we switch the x and y coordinates. Therefore, the reflection of (6,-5) across the line y=x is (-5,6).

To dilate a vector by a scale of -1.5, we multiply the vector by -1.5. Therefore, the resulting vector is (-5,6) multiplied by -1.5, which gives us:

(-5,6) * (-1.5) = (7.5, -9)

Answer:

Let x be the number of bottles of water that Yui buys, and let y be the number of sports drinks she buys.

Since Yui buys a total of 6 bottles of water and sports drinks, we know that:

x + y = 6

We also know that each bottle of water costs $1.50 and each sports drink costs $2.50, and that Yui spends a total of $10. Therefore, we can write another equation based on the total cost:

1.5x + 2.5y = 10

We now have a system of two equations with two variables:

x + y = 6

1.5x + 2.5y = 10

To solve for x and y, we can use substitution. Rearranging the first equation, we get:

x = 6 - y

Substituting this expression for x into the second equation, we get:

1.5(6 - y) + 2.5y = 10

Expanding and simplifying, we get:

9 - 1.5y + 2.5y = 10

Combining like terms, we get:

y = 2

Substituting this value of y back into the equation x + y = 6, we get:

x + 2 = 6

Solving for x, we get:

x = 4

Therefore, Yui buys 4 bottles of water and 2 sports drinks.

Using the defined iterative process, xₙ ₊ ₁ = 4xₙ(3 - xₙ) with x₀ = 5,

The value of x₁ is -40

The value of x₂ is -6880

From the question, we are to compute the values of x₁ and x₂ from the given iterative process

The definition of the iterative process is:

xₙ ₊ ₁ = 4xₙ(3 - xₙ)

From the given information,

x₀ = 5

To determine the value of x₁, we will substitute n = 0

xₙ ₊ ₁ = 4xₙ(3 - xₙ)

x₀ ₊ ₁ = 4x₀(3 - x₀)

x₁  = 4x₀(3 - x₀)

Substitute x₀ = 5

x₁  = 4(5)(3 - 5)

x₁  = 20(-2)

x₁  = -40

To determine the value of x₂, we will substitute n = 1

xₙ ₊ ₁ = 4xₙ(3 - xₙ)

x₁ ₊ ₁ = 4x₁(3 - x₁)

x₂ = 4x₁(3 - x₁)

Substitute x₁  = -40

x₂ = 4(-40)(3 - (-40))

x₂ = -160(43)

x₂ = -6880

Hence,

The value of x₁ is -40

The value of x₂ is -6880

Car Make and Model that i choose is Toyota RAV4

The Cost of this car as of today is about $27,000

To know the value of car after one year will be:

20% of $27,000

= $5,400.

So the car  value will be:

$27,000 - $5,400

= $21,600 after year 1

3.  Value of car after second year of ownership:

15% of $27,000

= $4,050.

So, the car  value will be:

The measure of the angle of the triangle ∠BCD = 13°

Given data ,

Let the triangle be represented as ΔBCD

Now , in triangle BCD, we are given the following angle measurements:

angle CDE = (9x - 12)°

angle BCD = (2x + 3)°

angle DBC = (3x + 5)°

From the exterior angle theorem , we get

∠CDE = ∠BCD + ∠DBC

On simplifying , we get

9x - 12 = 2x + 3 + 3x + 5

9x - 12 = 5x + 8

Subtracting 5x on both sides and adding 12 , we get

4x = 20

Divide by 4 on both sides , we get

x = 5

So , the measure of angle ∠BCD = 2(5) + 3
