what equation can be used to represent the relation shown in the table ?

Answer:

You can use the formula for the volume of a cuboid, which is Volume = length x width x height

You are given the volume of the cuboid as 108cm^3, the length as 4cm, and the width as 9cm. Let's substitute these values into the formula and solve for the height:

108cm^3 = 4cm x 9cm x height

To solve for height, you can divide both sides by 36 (which is equal to 4cm x 9cm) to isolate height:

108cm^3 ÷ 36 = 4cm x 9cm x height ÷ 36

3cm = height

So the height of the cuboid is 3cm.

From the diagram the value of v is √6

You should recall that Trigonometry is a branch of mathematics concerned with relationships between angles and ratios of lengths.

Using the trigonometrical ratios, we have

Tangent = opposite /adjacent

This implies that

√2/1 = 2√3/v

cross and multiplying to have

v√2 = 2√3

Rationalizing the denominator and making v the subject of the formular we have

v = 2√3/√2 *√2/√2

v = 2√2/2

Therefore the value of v is √6

The marginal cost function is $ 4000.72.

What is the marginal cost function?

The overall costs involved in producing an additional good are what is referred to as the marginal cost. Hence, it can be evaluated by changes in the costs associated with each extra unit. Marginal Cost is calculated as Total Expenditure Change / Unit Production Change.

Here, we have

Given: C(x) = 20+4000x+0.09x²

We have to find the marginal cost function.

We differentiate the given function and we get

C(x) = 20+4000x+0.09x²

C'(x) = 4000 + 2×0.09x

To determine how fast the cost is increasing when x=4.

C'(4) = 4000 + 2×0.09(4)

C'(4)  = 4000.72

Hence, the marginal cost function is $ 4000.72.

The volume of the triangular prism is 135 cm³.

To calculate the volume of a triangular prism, we multiply the area of the triangular base by the height of the prism.

Given the dimensions provided:

Base: Length = 5 cm, Width = 9 cm

Height: 6 cm

To find the area of the triangular base, we use the formula for the area of a triangle:

Area = (1/2) * base * height

Substituting the values:

Area = (1/2) * 5 cm * 9 cm

Area = 22.5 cm²

Now, to calculate the volume of the prism, we multiply the area of the base by the height:

Volume = Area * Height

Volume = 22.5 cm² * 6 cm

Volume = 135 cm³

Consequently, the triangular prism has a 135 cm3 volume.

Answer:

To solve this problem, we can use the laws of indices, specifically the law that states that (a^m)^n = a^(m*n).

So, we have:

(1/64)^(2/3) = (1^(2/3))/(64^(2/3))

Since any number raised to the power of 1 is itself, we can simplify the numerator to just 1.

Now, we have:

(1/64)^(2/3) = 1/(64^(2/3))

To evaluate 64^(2/3), we can use the law of indices again, which states that a^(1/n) = nth root of a. In this case, we have:

64^(2/3) = (64^(1/3))^2 = 4^2 = 16

So, substituting this back into the original expression, we have:

(1/64)^(2/3) = 1/16

Therefore, (1/64)^(2/3) simplifies to 1/16.

Step-by-step explanation:

Answer:

Using the law of indices, we have:

(1/64)^(2/3) = (1^(2/3))/(64^(2/3))

Now we need to simplify the denominator by finding the cube root of 64:

64^(1/3) = 4

Substituting this value in the original expression, we get:

(1/64)^(2/3) = (1^(2/3))/(4^2)

Simplifying further, we have:

(1/64)^(2/3) = 1/16

a) A 2*2 area model would not work to multiply (x + 3)(2x⁴ − 3x³ − 2x² − 4x − 1) because this expression has 5 terms, and a 2*2 area model can only accommodate 4 smaller areas.

b) The area model for (x + 3)(2x⁴ − 3x³ − 2x² − 4x − 1) with the correct lengths and widths labeled has been attached below.

c) The final total area is 2x² - 10x - 15.

An area model is a way to visualize multiplication by breaking up the larger rectangle into smaller rectangles whose areas represent the products of the terms being multiplied. To determine the correct rows and columns for the area model, we count the number of terms in each factor and use that as a guide. For example, if one factor has 3 terms and the other has 4 terms, we would use a 3x⁴ area model, with 3 rows and 4 columns.

a) A 2*2 area model would not work to multiply (x + 3)(2x⁴ − 3x³ − 2x² − 4x − 1) because this expression has 5 terms, and a 2*2 area model can only accommodate 4 smaller areas.

b) The area model for (x + 3)(2x⁴ − 3x³ − 2x² − 4x − 1) with the correct lengths and widths labeled has been attached below.

    2x⁴ − 3x³ − 2x² − 4x − 1

 +---------------------------------------

x  |   2x⁵    -3x⁴    -2x³    -4x²   -x

 |

3  |   6x⁴    -9x³    -6x²    -12x    -3

 +---------------------------------------

c) To find the total area of a rectangle with length (x + 8) and width (x − 5), we can use an area model with 2 rows and 2 columns. The length (x + 8) corresponds to one dimension of the rectangle, while the width (x − 5) corresponds to the other dimension. The area of each smaller rectangle in the model represents the product of one term from each factor.

     x + 8      x - 5

 +--------------------

x  |  x² + 8x   x² - 5x

 |

-5 | -5x + -40   -5x + 25

 +--------------------

The final total area can be found by adding up the areas of the smaller rectangles:

Total area = x² + 8x + x² - 5x - 5x - 40 + 25

= 2x² - 10x - 15

= 2x² - 10x - 15.

We may divide the composite figure into smaller forms and sum up their areas to determine the area of the overall figure. Here is one method for breaking down the figure:

A rectangle and two triangles make up the figure.

The rectangle has an area of 80 square units since it is 10 units long and 8 units wide.

The two triangles have right triangles with four and six unit-long legs, respectively. The equation (base * height) / 2 may be used to calculate each triangle's area.

The area of the triangle on the left is (4 * 8) / 2 or 16 square units since its base is 4 units and its height is 8 units (the length of the rectangle).

Answer:

Find the components of the line (x,y)

And then use Tan ^-1(y/x)= Theta or angle

I hope you understand, and I go explain further.

Step-by-step explanation: In "simple terms". Slope is rise/run. Rise is the change in y value, which will equal the length of the opposite side of the right triangle. Run is the change in x value, which is the length of the adjacent side. The trigonometric function Tangent is opposite/adjacent. Use the inverse tangent of the slope to find the angle.

The only catch is that sometimes inverse tangent will give you a negative angle. It is generally not acceptable to provide the angle in a triangle as the negative angle. If you get a negative angle, use the absolute value of the angle.

The percentage of reduction in consumption required to keep the same expenditure is 25%.

Inflation is an economic phenomenon that occurs when the prices of goods and services increase over time.

To find out the percentage of reduction in consumption, we need to calculate the difference between the current and the original prices of the butter.

This can be done by subtracting the original price of the butter from the current price of the butter (25% costlier).

The difference can be expressed as a percentage by dividing the difference by the original price.

Therefore, the percentage of reduction in consumption required to keep the same expenditure is 25%.

This means that a housewife needs to reduce her consumption of butter by 25% in order to keep her expenditure the same.
