The profit when producing 10 units can be calculated by substituting X = 10 into the profit function. Thus, the profit is F = 100(10) - 4(10) - 200 = 1000 - 40 - 200 = 760.
To calculate the profit when the company produces 10 units, we substitute X = 10 into the profit function F = 100X - 4X - 200:
F = 100(10) - 4(10) - 200
= 1000 - 40 - 200
= 760
Therefore, the profit when producing 10 units is £760.
To determine the producer surplus, we need to know either the market price or the cost function. The producer surplus is calculated as the difference between the total revenue and the total variable cost. Without additional information, we cannot determine the exact value of the producer surplus when producing 10 units.
However, if we have the market price or the cost function, we can calculate the total revenue and the total variable cost and then find the producer surplus.

Can anyone help me pls ? ( it’s talking about the blue dot ) will give brainliest!!
Answer:
NO
Step-by-step explanation:
From the graph attached,
Equation of the line parallel to x-axis is y = 3.
Since, the line is dotted line, equation will be an inequality (having sign of < or >)
Now shaded region is below the line so equation of the inequality will be,
y < 3
Any point below the dotted line will be the solution of the given inequality.
Therefore, blue dot on the dotted line represented by y = 3 will not be the solution of the inequality.
Answer is NO.
The temperature at the point (x, y, z) in a substance with conductivity
K = 7.5 is u(x, y, z) = 3y² + 3z².
Find the rate of heat flow inward across the cylindrical surface
y² + z² = 6, 0 ≤ x ≤ 3
The integration is ∫∫(q · dS) = ∫[0 to √6] ∫[0 to √6] (-45y - 45z) dy dz.
The rate of heat flow inward across the cylindrical surface y² + z² = 6, 0 ≤ x ≤ 3 can be determined by calculating the flux of the heat vector field through the surface.
To find the rate of heat flow, we need to calculate the surface integral of the heat flux vector across the given cylindrical surface. The heat flux vector is given by q = -K∇u, where K is the conductivity and ∇u is the gradient of the temperature function u(x, y, z).
First, we find the gradient of u:
∇u = (∂u/∂x)i + (∂u/∂y)j + (∂u/∂z)k
= 0i + (6y)j + (6z)k
Then, we calculate the heat flux vector:
q = -K(∇u)
= -7.5(0i + (6y)j + (6z)k)
= -45yj - 45zk
Next, we calculate the surface area element vector, dS, of the cylindrical surface. Since the surface is defined by y² + z² = 6, we can parameterize it as r(y,z) = yi + zk. Taking the cross product of the partial derivatives, we obtain dS = (∂r/∂y) x (∂r/∂z) dy dz = (-j -k) dy dz.
Finally, we can calculate the surface integral by integrating the dot product of q and dS over the given cylindrical surface:
∫∫(q · dS) = ∫∫(-45yj - 45zk) · (-j -k) dy dz
To find the limits of integration, we note that the surface extends from y² + z² = 6 to the origin, which corresponds to 0 ≤ y² + z² ≤ 6. Since the surface is symmetric, we can integrate over a quarter of the surface, from y = 0 to y = √6 and z = 0 to z = √6.
Performing the integration, we get:
∫∫(q · dS) = ∫[0 to √6] ∫[0 to √6] (-45y - 45z) dy dz
Evaluating this double integral will give us the rate of heat flow inward across the cylindrical surface.

Find the deflection u (x, y, t) satisfying the wave equation utt = 4 (uxx + Uyy) for a rect- = angular plate with fixed ends and dimensions: horizontal a = 2pi and vertical b initial velocity is g(x, y) = 0 The initial displacement is f(x, y) = - 3sin(5x) * sin(6y) + 11sin(6x) * sin(9y)
TheThe general solution to the wave equation utt = 4 (uxx + Uyy) is given by the D’Alembert’s formula. Therefore, the solution to the given problem is obtained by finding the specific form of the initial conditions u (x, y, 0) = f (x, y) and ut (x, y, 0) = g (x, y) and then use these values to find u (x, y, t) using the D’Alembert’s formula.
Let us find the form of the wave u(x,y,t) that satisfies the wave equation utt = 4 (uxx + Uyy) given the initial displacement f(x,y) = -3sin(5x)sin(6y) + 11sin(6x)sin(9y) and g(x,y) = 0.
Solution:
The D’Alembert’s formula for the wave equation is given by:
`u(x,y,t) = (1/2) [f(x+ct,y) + f(x-ct,y)] + (1/(2c)) ∫_((x-ct))^(x+ct)∫_((y-c(t-s)))^(y+c(t-s)) g(s,r) dr ds`
where c is the speed of the wave. Comparing with the wave equation `utt = c^2(uxx + uyy)` we have `c = 2`
Therefore, the solution to the wave equation is given by:
`u(x,y,t) = (1/2) [-3sin(5(x+2t))sin(6y) -3sin(5(x-2t))sin(6y) +11sin(6(x+2t))sin(9y) +11sin(6(x-2t))sin(9y)]`
Hence, the solution is:
`u(x,y,t) = (1/2) [-3sin(5(x+2t))sin(6y) -3sin(5(x-2t))sin(6y) +11sin(6(x+2t))sin(9y) +11sin(6(x-2t))sin(9y)]`
So, this is the required solution.

To determine whether the equation y'' = −3x([tex]y')^2[/tex]is a second-order linear differential equation, we need to examine its form.
A second-order linear differential equation has the general form:

In the given equation, [tex]y'' = -3x(y')^2,[/tex]we can observe that the dependent variable y only appears in the squared term [tex](y')^2.[/tex]This indicates that the equation is not linear in y or its derivatives. It contains a non-linear term [tex](y')^2[/tex]multiplied by the function -3x.

Suppose Y varies directly with X and Y equals 10 when X equals -3 what direct variation equation relates XNY what is the value of Y when X equals -1
Answer:
Expression: Y = -10/3 X
Y = 10/3
Step-by-step explanation:
If Y varies directly as X, then;
Y∝X
Y = kX
k is the constant of variation
If Y = 10 and X = -3
10 = -3k
k = -10/3
Substitute k = -10/3 into the expression Y = kX
Y = -10/3 X
This gives the required expression
To get the value of Y when X = -1
Recall that Y = kX
Y = -10/3 (-1)
Y = 10/3
Hence the value of Y is 10/3

Answer:

Step-by-step explanation:
If the 3 points are collinear then:
Slope of AB = Slope of BC and so
(0-2)/(b + 6) = (-4-0)/( 3 - b)

A. Add 3 to both sides and substract 8x from both sides
B. The equation is already in standard from
C. Substract 3 from sides and substract 8x from both sides
D. Add 3 to both sides and add 8x from both sides
The two necessary steps to put this equation into standard form is A) Add 3 to both sides and subtract 8x from both sides.
To put the equation x² - 3x + 27 = 8x - 3 into standard form, the two necessary steps are:
A. Add 3x to both sides: By adding 3 to both sides of the equation, we eliminate the constant term -3 on the right side and move it to the left side.
x² - 3x + 3x + 27 = 8x - 3 + 3x
x² + 27 = 11x
B. Subtract 11x from both sides: By subtracting 8x from both sides of the equation, we eliminate the term 8x on the right side and move it to the left side.
x² + 27 - 11x = 11x - 11x
x² - 11x + 27 = 0
Therefore, the equation in standard form is x² - 11x + 27 = 0. Therefore, the correct answer is option A.

A = 672 cm²
Given that;
In a hexagon;
Apothem of the hexagon = 14 cm
And, perimeter of the hexagon: 96 cm
Since, We know that,
Area of the hexagon = [(3√3) / 2] a²
where, a is the measure of the side
Since, hexagon has 6 sides.
Perimeter = 6a
96 cm = 6a
96 cm / 6 = a
16 = a
We can also use the area of a triangle to approximate the area of the hexagon. There are 6 triangles in the hexagon .
Area of a triangle = (height x base) / 2
A = (14 cm x 16 cm) / 2
A = 224 / 2

What is the appropriate measure of variability for the data shown, and what is its value?

The range is the best measure of variability, and it equals 45.
The IQR is the best measure of variability, and it equals 45.
The range is the best measure of variability, and it equals 16.
The appropriate measure of variability for the given data is the IQR, and its value is 16.
Based on the given stem-and-leaf plot, which represents the scores earned in a flower-growing competition, we can determine the appropriate measure of variability for the data.
The stem-and-leaf plot shows the individual scores, and to measure the spread or variability of the data, we have two commonly used measures: the range and the interquartile range (IQR).
The range is calculated by subtracting the smallest value from the largest value in the dataset. In this case, the smallest value is 20, and the largest value is 65. Therefore, the range is 65 - 20 = 45.
The interquartile range (IQR) is a measure of the spread of the middle 50% of the data. It is calculated by subtracting the first quartile (Q1) from the third quartile (Q3). Looking at the stem-and-leaf plot, we can identify the quartiles. The first quartile (Q1) is 25, and the third quartile (Q3) is 41. Therefore, the IQR is 41 - 25 = 16.
In this case, both the range and the IQR are measures of variability, but the IQR is generally preferred when there are potential outliers in the data. It focuses on the central portion of the dataset and is less affected by extreme values. Therefore, the appropriate measure of variability for the given data is the IQR, and its value is 16.
