Answer:

I think the answer is 366.6666666666

Step-by-step explanation:

The slope of the line that divides the region bounded by the parabola \(y=5x-3x^2\)and the x-axis into two regions with equal area is 5.

To find the slope of the line that divides the region into two equal areas, we need to determine the point of intersection between the parabola and the x-axis. Since the line passes through the origin, its equation will be y = mx, where m represents the slope.

Setting the equation of the parabola equal to zero, we find the x-values where the parabola intersects the x-axis. By solving the equation\(5x - 3x^2 = 0\), we get x = 0 and x = 5/3.

To divide the region into two equal areas, the line must pass through the midpoint between these x-values, which is x = 5/6. Plugging this value into the equation of the line, we have y = (5/6)m.

Since the areas on both sides of the line need to be equal, we can set up an equation using definite integrals. By integrating the equation of the parabola from 0 to 5/6 and setting it equal to the integral of the line from 0 to 5/6, we can solve for m. After performing the integration, we find that m = 5.

Therefore, the slope of the line that divides the region into two equal areas is 5.

Step-by-step explanation:

Answer:

-8

Step-by-step explanation:

-8 x 3 = -24

-24 is 16 units less than -8

Answer:

(-8,-10)

Step-by-step explanation:

we have the two equations x-2y=12 and y=3x+14.

I'm going to assume this is a system of equations and we are looking for the solution.

we can use the substitution method as y is "defined".

x-2y= 12

substitute y = 3x + 14

x-2(3x+14)=12

distribute

x - 6x -28 = 12

combine like terms

-5x - 28 = 12

add 28 to both sides

-5x = 40

divide both sides by -5

x = -8

Now we plug in the value of x into one of the equations and solve for y

y = 3x + 14

x = -8

y = 3(-8) + 14

y = -24 + 14

y = 10

the solution is (-8,-10)

According to the given image, the given function is increasing at (C) x > 2.

A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X.

The sets X and Y are collectively referred to as the function's domain and codomain, respectively.

The relationship between the input or domain and the output or range is known as the function rule.

If and only if there is a single value in the range for each domain value, a relation is a function.

A function is denoted by the notation f x, where x is the input value.

A function has the general form y = f x.

So, let's consider the given image:

A bell-shaped histogram is a type of graph that displays a normal distribution, which is a probability distribution that is symmetrical and has a characteristic bell shape.

The bell-shaped histogram is created by plotting the data on a horizontal axis and the frequency or probability on a vertical axis. The data points are grouped into intervals called bins, and the number of data points that fall into each bin is plotted as a bar. The bars are typically drawn adjacent to one another and connected with lines to create a continuous curve that represents the normal distribution.

The resulting histogram will have a characteristic bell shape, with a high point at the mean, and decreasing frequency or probability as the values move away from the mean in either direction. The width of the curve is determined by the standard deviation of the data, with wider curves indicating greater variation in the data.

The bell-shaped histogram is commonly used in statistical analysis to represent normally distributed data, such as the heights or weights of a population, test scores, or other measurements that tend to cluster around a central value with a predictable range of variation.

With the help of ratio, we know that when the length will be 1cm then the width of the rectangle will be 2cm.

In mathematics, a ratio shows how frequently one number appears in another.

For instance, the ratio of oranges to lemons in a fruit plate would be eight to six if there were eight oranges and six lemons.

Oranges make up 8:14 of the total fruit, whereas lemons make up 6:8 of the total fruit.

So, 1st we have a rectangle which:

length 7cm

width 14cm

Just get the ratio of length:width:

Answer:

The volume of the solid is 4,503.22 in³.

What is volume?

A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder, or a sphere. Different shapes have different volumes

The volume of a solid with a hollow cylinder can be calculated by subtracting the volume of the inner cylinder from the volume of the outer cylinder.

Assuming the dimensions in the figure are in inches, the outer cylinder has a height of 17 inches and a radius of 9 inches, so its volume is:

\(V_{outer} = \pi * r^2 * h\)

= π × 9² × 17 ≈ 4,842.51 in³

The inner cylinder has a height of 12 inches and a radius of 3 inches, so its volume is:

\(V_{inner} = \pi * r^2 * h\) = π × 3² × 12 ≈ 339.29 in³

To find the volume of the solid, we need to subtract the volume of the inner cylinder from the volume of the outer cylinder:

\(V_{solid }= V_{outer} - V_{inner}\)

≈ 4,842.51 - 339.29 ≈ 4,503.22 in³

Hence, the volume of the solid is 4,503.22 in³.

a. The maximum of the equation Q = 5x + 3y is; 24.

The minimum of the equation Q is; 14.

b) The way the maximum and minimum would change in the new equation compared to the original equation is;

-24 ≤ -5x - 3y ≤ -14.

We are given the equation as;  Q = 5x + 3y

The constraints:

3y + 6 ≥ 5x

y ≤ 3

4x  ≥ 8

The constraint 4x ≥ 8 is basically telling us that x ≥ 2, and then;

3y + 6 ≥ 5x and both together tells us that 10 ≤ 5x ≤ 3y + 6

Thus, we have;

10 + 3y ≤

5x + 3y ≤

6y + 6 ≤

6*3 + 6

= 18 + 6

= 24

Due to the fact that we are given that y ≤ 3, then we must get 10 + 3y ≤ 6y + 6, which suggests that 4 + 3y ≤ 6y.

Thus, 4 ≤ 3y

Now, we have;

14 = 10 + 4 ≤

10 + 3y ≤

5x + 3y ≤ 24, and then also the following:

a. The maximum of Q = 5x + 3y is 24, and the minimum of Q is 14.

b. If the equation Q = 5x + 3y was changed to Q = -5x - 3y, the new maximum would definitely now be the negative of the first original minimum, and as such it means that the new minimum would be the negative of it's original maximum.

This is because from 14 ≤ 5x + 3y ≤ 24, we obtain;

14 ≤ 5x + 3y and 5x + 3y ≤ 24

We can multiply both sides of both inequalities by -1, and then switch the direction of inequalities, and so we now have;

The statement "If C is the input-output matrix for an economy with gross production vector x, then Cx is the net production vector" is describing the relationship between the input-output matrix C, the gross production vector x, and the net production vector.

In an economy, the input-output matrix C represents the interdependencies between different sectors or industries. Each entry in the matrix represents the amount of output from one sector that is required as an input by another sector. The gross production vector x represents the total output produced by each sector without considering the interdependencies.

When we multiply the input-output matrix C by the gross production vector x, the result Cx represents the net production vector.

The net production vector takes into account the interdependencies between sectors by subtracting the inputs required from other sectors from the gross production. It gives us the final production available for consumption or further production.

In summary, by multiplying the input-output matrix C by the gross production vector x, we obtain the net production vector Cx, which accounts for the interdependencies between sectors and represents the final output available for consumption or further production.

To solve for x in the given equation, we need to use the matrix representation of the linear transformation.

Let A be the matrix that represents the linear transformation 2 → 2. Since we know that (1, 2) is mapped to (1 2, 41 52), we can write:

A * (1, 2) = (1 2, 41 52)

Expanding the matrix multiplication, we get:

[ a b ] [ 1 ] = [ 1 ]
[ c d ] [ 2 ]   [ 41 ]
            [ 52 ]

This gives us the following system of equations:

a + 2b = 1
c + 2d = 41
a + 2c = 2
b + 2d = 52

Solving this system of equations, we get:

a = -39/2
b = 40
c = 41/2
d = 5

Now, we can use the matrix A to find the image of (3,8) under the linear transformation:

A * (3,8) = [ -39/2 40 ] [ 3 ] = [ -27 ]
            [ 41/2  5 ] [ 8 ]   [ 206 ]

Aggregate Demand (AD) is a macroeconomic concept that represents the total demand for goods and services in an economy. The X factor in the AD equation represents exports, which are an important part of the economy.

AD is calculated by adding up the individual components of demand, which include consumer spending (C), investment spending (I), government spending (G), and net exports (X-M). The X-M component represents the difference between exports (X) and imports (M).

The X component in the equation represents exports, which are the goods and services produced domestically and sold to foreign countries. Exports are an important part of the economy as they generate income and create jobs. The M component in the equation represents imports, which are the goods and services purchased from foreign countries and consumed domestically. Imports can have a negative impact on the economy as they represent a drain on resources and can lead to a trade deficit. The X factor in the equation is used to represent exports because it is a variable that can change over time. Factors that can affect exports include exchange rates, tariffs, and global demand for certain products. If the exchange rate between two currencies changes, it can make exports more or less expensive for foreign buyers, which can affect the level of exports. Tariffs are taxes on imports, which can make domestic products more competitive in foreign markets.
