Answer:

y = -3x + 5

Step-by-step explanation:

You want it in y = mx + b  form

-5 = -y - 3x

Add y to both sides

-5 + y = -y + y - 3x

-5 + y = -3x

Add 5 to both sides

- 5 + 5 + y = -3x + 5

y = -3x + 5

Step-by-step explanation:

(A) The maximum profit for standard model is $28,480. (B)The maximum profit for portable model is $28,480.

The given problem is related to profit maximization and a company that manufactures two types of personal computers, a standard model, and a portable model. Production requires capital expenditure and labor hours, and the firm has limited resources of capital and labor hours available.

Part A:

We can use linear programming to find the optimal solution.

Let x and y be the number of standard computers and portable computers manufactured, respectively.

We have the following objective function and constraints:

Objective Function: Profit = 320x + 220y

Maximize profit (z)Subject to:400x + 250y ≤ 20,000 (Capital expenditure constraint)

40x + 30y ≤ 2,160 (Labor hours constraint)where x and y are non-negative.

Using these inequalities, we can plot the feasible region as follows:

graph{(20000-400x)/250<=(2160-40x)/30 [-10, 100, -10, 100]}

The feasible region is a polygon enclosed by the lines 400x + 250y = 20,000, 40x + 30y = 2,160, x = 0, and y = 0.

Now, we need to find the corner points of the feasible region to determine the maximum profit that the company can make by producing the maximum number of computers.

To do so, we can solve the system of equations for each pair of lines:400x + 250y = 20,000 → 4x + 2.5y = 200, 40x + 30y = 2,160 → 4x + 3y = 216, x = 0 → x = 0, y = 0 → y = 0

The corner points of the feasible region are (0, 72), (48, 60), and (50, 0).

We can substitute these values into the objective function to determine the maximum profit:

Profit = 320x + 220y = 320(0) + 220(72) = $15,840 (at point A),

320(48) + 220(60) = $28,480 (at point B),

320(50) + 220(0) = $16,000 (at point C).

Therefore, the maximum profit is $28,480, which can be obtained by producing 48 standard computers and 60 portable computers.

Part B:

Each standard computer contributes a profit of $320 and each portable computer contributes a profit of $220.

To find out how much profit the company will make by producing the maximum number of computers determined in part A, we can use the following formula:

Profit = 320x + 220ywhere x = 48 (number of standard computers) and y = 60 (number of portable computers)

Substituting these values, we getProfit = 320(48) + 220(60) = $28,480

Therefore, the company will make a profit of $28,480 by producing the maximum number of computers determined in part A.

Answer:

Question 1

Ordered pair (2, -3) satisfies y ≥ x - 5 but does not satisfy y ≤ 2x-8

Question 2

Ordered pair (0,4) does satisfy both inequalities:
y ≤ -x + 4 and y ≥ 5x - 3

Step-by-step explanation:

Question 1

The ordered pair is (2, -3); therefore x = 2, y = -3

Plug these values into the left and right side of each inequality and see if these values satisfy the inequality

For y ≥ x - 5
LHS = -3, RHS = 2 - 5 = -3

Is -3 ≥ -3? Of course; in fact it is = and it only need to satisfy either = or >

For y ≤ 2x-8
LHS = -3, RHS = 2(2) - 8 = 4 - 8 = -4

Is -3 ≤ -4? NO. -3 is greater than -4
(remember in negative  numbers -4 lies further to the left than -3 on the number line so -4 is less than -3)

Question 2

Given ordered pair is (0,4)

For y ≤ -x + 4

LHS = 4, RHS = -0 + 4 = 4

Is 4 ≤ 4? YES

For y ≥ 5x -3

LHS = 4, RHS = 5(0) -3 = 0 - 3 = -3

Is 4 ≥ -3? Of course. All positive numbers are greater than negative numbers

The length of the midsegment of this trapezoid is 8 units. Mid segment of a trapezoid is equal to half of sum of its two parallel sides.

A midsegment of a triangle is defined as a line segment that connects the midpoints or center of two opposite sides of a triangle or adjacent sides of a triangle. The midsegment theorem is defined as a line segment that joins the midpoints of any two sides of a triangle is parallel to the third side of a triangle and is half of it.

The converse of the midsegment theorem states that When a line segment joins two midpoints of two opposite sides of a triangle and is parallel to the third side of a triangle.

So,

Length of mid segment = 1/2(AB+CD)

Applying distance formula,

AB = \(\sqrt{(7-2)^{2} + (4-4)^{2} }\) = \(\sqrt{5^{2} + 0 }\) = 5

CD = \(\sqrt{(9+2)^{2} + (-1+1)^{2} }\) = \(\sqrt{11^{2} + 0 }\) = 11

Hence,

the length of mid-segment = 1/2(5 + 11) = 1/2(16).

⇒ length of mid-segment = 8 unit.

The diameter of a hemisphere with a volume of 7195 in^3 is 117.2 in.

In the given question we have to find the diameter of a hemisphere with a volume of 7195 in^3.

As we know that the volume of hemisphere is (2/3)πr^3 cubic unit.

The given volume of hemisphere is 7195 in^3.

Now we firstly finding the radius of hemisphere then we find the diameter of hemisphere

The volume of hemisphere = 7195 in^3

(2/3)πr^3 = 7195

We know that; π = 22/7

(2/3) * (22/7) *r^3 = 7195

44/21 * r^3 = 7195

Multiply by 21/44 on both side, we get

r^3 = 7195*21/44

r^3 = 3433.98

r^3 = 3434 (approx)

Taking cube root on both side, we get

r = 58.60

Now finding the diameter,

Diameter = 2*radius

Diameter = 2*58.60

the critical load of the round wooden dowel is determined by using the Euler buckling formula, which is given by:

P_cr = (π^2 * E * I) / L^2

Where P_cr is the critical load, E is the modulus of elasticity (given as 12 GPa), I is the area moment of inertia (for a round wooden dowel it is π*d^4/64), and L is the length of the dowel (given as 0.75 m). Substituting these values, we get:

P_cr = (π^2 * 12e9 * π*(10/1000)^4/64) / (0.75^2)

P_cr = 91.34 N

Therefore, the critical load of the round wooden dowel is 91.34 N.

In explanation, the Euler buckling formula is used to determine the critical load of slender columns or rods that are subjected to compressive forces. The formula takes into account the modulus of elasticity of the material, the length of the column, and the area moment of inertia of the cross-section. The critical load is the maximum load that the column can withstand without buckling or collapsing under compressive forces.

The volume V of solid S is e - 1 cubic unit.

What is Volume?

Volume refers to the measure of three-dimensional space occupied by an object or a region. It quantifies the amount of space enclosed by the boundaries of an object or contained within a given region. In mathematical terms, volume is often calculated by integrating the cross-sectional areas of the object or region along a particular axis. Volume is typically expressed in cubic units, such as cubic meters (m^3) or cubic centimeters (cm^3). It is an essential concept in geometry, physics, engineering, and other scientific fields where the measurement of three-dimensional space is involved.

To find the volume of solid S, we need to integrate the areas of the cross sections perpendicular to the x-axis along the interval \([e, \infty).\)

The area of each square cross-section is equal to the square of the side length, which in this case is \(y = \sqrt{\ln(x)}.\)

Therefore, the volume V of solid S can be calculated as:

\(V = \int_{e}^{\infty} (\sqrt{\ln(x)})^2 dx\)

To evaluate this integral, we can simplify the expression:

\(V = \int_{e}^{\infty} \ln(x) dx\)

Using integration by parts, we let \(u = \ln(x)\)and dv = dx:

\(du = \frac{1}{x} dx\\v = x\)

Applying the integration by parts formula:

\(V = [uv] - \int v du= [x \ln(x)] - \int x \left(\frac{1}{x}\right) dx= x \ln(x) - \int dx= x \ln(x) - x + C\)

Evaluating the definite integral:

\(V = [x \ln(x) - x]_{e}^{\infty}= (\infty \cdot \ln(\infty) - \infty) - (e \cdot \ln(e) - e)= \infty - 0 - (1 - e)= e - 1\)

Therefore, the volume V of solid S is e - 1 cubic unit.

The vector function that represents the curve of intersection of the cone and the plane is:

r(t) = [t, (t^2 - 9) / 6, √(t^2 + ((t^2 - 9)/6)^2)]

For a vector function that represents the curve of intersection between the cone and the plane, we need to set the equations of the cone and the plane equal to each other and solve for x, y, and z.

The cone equation is given as: z = √(x^2 + y^2)

The plane equation is given as: z = 3 + y

Setting these two equations equal to each other, we have:

√(x^2 + y^2) = 3 + y

To eliminate the square root, we can square both sides of the equation:

x^2 + y^2 = (3 + y)^2

x^2 + y^2 = 9 + 6y + y^2

Simplifying the equation, we have:

x^2 - 6y = 9

Now we can express x and y in terms of a parameter t to create the vector function r(t):

x = t

y = (t^2 - 9) / 6

Substituting these values back into the cone equation to find z:

z = √(x^2 + y^2) = √(t^2 + ((t^2 - 9)/6)^2)

Therefore, the vector function that represents the curve of intersection of the cone and the plane is:

r(t) = [t, (t^2 - 9) / 6, √(t^2 + ((t^2 - 9)/6)^2)]

Note that this is a parametric representation of the curve, where t is the parameter that determines points on the curve.
