The can constructed using the LEAS (Lowest Empty Space) algorithm should have a diameter between 4 cm and 8 cm and a capacity of 250 cm.

The LEAS algorithm aims to minimize the empty space in a container while maintaining the desired capacity. To determine the dimensions of the can, we need to find the height and diameter that satisfy the given conditions.

Let's assume the diameter of the can is d cm. The radius of the can would then be r = d/2 cm. To calculate the height, we can use the formula for the volume of a cylinder: V = πr^2h, where V is the desired capacity of 250 cm. Rearranging the formula, we have h = V / (πr^2).

To minimize the empty space, we can use the lower limit for the diameter of 4 cm. Substituting the values into the formulas, we find that the radius is 2 cm and the height is approximately 19.87 cm.

Next, let's consider the upper limit for the diameter of 8 cm. Using the same formulas, we find that the radius is 4 cm and the height is approximately 9.93 cm.

Therefore, the can constructed using the LEAS algorithm can have dimensions of approximately 4 cm in diameter and 19.87 cm in height, or 8 cm in diameter and 9.93 cm in height, while maintaining a capacity of 250 cm.

The required step is Multiply the top equation by -3 and the bottom equation by 2.

In this case, looking at the coefficients of y in the two equations, we can see that multiplying the top equation by -3 and the bottom equation by 2 will make the coefficients of y additive inverses:

(-3)(4x - 2y) = (-3)(7)

2(3x - 3y) = 2(15)

This simplifies to:

-12x + 6y = -21

6x - 6y = 30

Now, when you add these two equations, the variable y will be eliminated:

Answer:

A

Step-by-step explanation:

The derivative of f(x) = 2 + 7√x is f'(x) = (7/2√x). Evaluating f(1), f'(2), and f'(3) gives f(1) = 9, f'(2) = 7/4, and f'(3) = 7/6.

To find the derivative f'(x) of the given function f(x) = 2 + 7√x, we can use the four-step process:

Step 1: Identify the function. In this case, the function is f(x) = 2 + 7√x.

Step 2: Apply the power rule. The power rule states that if we have a function of the form f(x) = a√x, the derivative is f'(x) = (a/2√x). In our case, a = 7, so f'(x) = (7/2√x).

Step 3: Simplify the expression. The expression (7/2√x) cannot be further simplified.

Step 4: Substitute the given values to find f(1), f'(2), and f'(3).

- f(1) = 2 + 7√1 = 2 + 7(1) = 2 + 7 = 9.

- f'(2) = (7/2√2) is the derivative evaluated at x = 2.

- f'(3) = (7/2√3) is the derivative evaluated at x = 3.

Therefore, f(1) = 9, f'(2) = 7/4, and f'(3) = 7/6.

The limits of integration are from 1 to 5 because we are rotating the curve on the interval 1 < x < 5.

To calculate the surface area of the solid, we can use the formula for the surface area of a solid of revolution:

S = ∫[a,b] 2πy√(1+(dy/dx)^2) dx.

First, we need to find the derivative dy/dx of the given curve y = 5xe^(-6x). Taking the derivative, we get dy/dx = 5e^(-6x) - 30xe^(-6x).

Next, we substitute the expression for y and dy/dx into the formula:

S = ∫[1,5] 2π(5xe^(-6x))√(1+(5e^(-6x) - 30xe^(-6x))^2) dx.

This integral represents the surface area of the curved portion of the solid.

To account for the flat portion of the solid, we need to add the surface area of the circle formed by rotating the line x = -1. The radius of this circle is the distance between the line x = -1 and the curve y = 5xe^(-6x). We can find this distance by subtracting the x-coordinate of the curve from -1, so the radius is (-1 - x). The formula for the surface area of a circle is A = πr^2, so the surface area of the flat portion is:

A = π((-1 - x)^2) = π(x^2 + 2x + 1).

Thus, the integral for the total surface area is:

S = ∫[1,5] 2π(5xe^(-6x))√(1+(5e^(-6x) - 30xe^(-6x))^2) dx + ∫[1,5] π(x^2 + 2x + 1) dx.

Let's evaluate the limits one by one:

(a) [tex]\(\lim_{{x \to -3}} \frac{{3x^2 + 2x - 15}}{{5 - x}}\)[/tex]

To find the limit, we substitute the value -3 into the expression:

[tex]\(\lim_{{x \to -3}} \frac{{3(-3)^2 + 2(-3) - 15}}{{5 - (-3)}} = \lim_{{x \to -3}} \frac{{9 - 6 - 15}}{{5 + 3}} = \lim_{{x \to -3}} \frac{{-12}}{{8}} = -\frac{{3}}{{2}}\)[/tex]

Therefore, the limit is [tex]\(-\frac{{3}}{{2}}\)[/tex].

(b) [tex]\(\lim_{{u \to 2}} \frac{{2u + 2}}{{u^2 + 3}}\)[/tex]

Again, we substitute the value 2 into the expression:

[tex]\(\lim_{{u \to 2}} \frac{{2(2) + 2}}{{2^2 + 3}} = \lim_{{u \to 2}} \frac{{4 + 2}}{{4 + 3}} = \lim_{{u \to 2}} \frac{{6}}{{7}} = \frac{{6}}{{7}}\)[/tex]

Therefore, the limit is [tex]\(\frac{{6}}{{7}}\)[/tex].

(c) [tex]\(\lim_{{x \to 0}} \frac{{\sqrt{{9x^2 + 5x + 1}}}}{{2x - 1}}\)[/tex]

Substituting 0 into the expression:

[tex]\(\lim_{{x \to 0}} \frac{{\sqrt{{9(0)^2 + 5(0) + 1}}}}{{2(0) - 1}} = \lim_{{x \to 0}} \frac{{\sqrt{{1}}}}{{-1}} = \lim_{{x \to 0}} -1 = -1\)[/tex]

Therefore, the limit is -1.

(d) [tex]\(\lim_{{x \to \infty}} (1 - 2020x)^{\frac{{1}}{{2}}}\)[/tex]

As x approaches infinity, the term [tex]\((1 - 2020x)\)[/tex] tends to be negative infinity. Therefore, the expression [tex]\((1 - 2020x)^{\frac{{1}}{{2}}}\)[/tex] is undefined.

Therefore, the limit does not exist (DIV).

To evaluate the given integral, we can apply integration by parts, which is a technique used to integrate the product of two functions. The integration by parts formula is given as ∫u dv = uv - ∫v du, where u and v are functions of the variable of integration.

Let's choose u = sec(-42) and dv = de. We need to find du and v in order to apply the integration by parts formula. Differentiating u with respect to the variable of integration, we have du = sec(-42)tan(-42)d(-42), which simplifies to du = sec(-42)tan(-42)d(-42). To find v, we integrate dv, which gives v = e.

Applying the integration by parts formula, we have ∫2sec(-42) de = 2sec(-42)e - ∫e(sec(-42)tan(-42)d(-42)). Simplifying the expression, we have ∫2sec(-42) de = 2sec(-42)e + ∫sec(-42)tan(-42)d(-42).

To find the equation of a line perpendicular to the given function y = 3x + 7 at x = 0, we first need to determine the slope of the given function. The given function is in the form y = mx + b, where m is the slope. In this case, the slope is 3.

For a line to be perpendicular to another line, their slopes must be negative reciprocals of each other. The negative reciprocal of 3 is -1/3.

Using the slope-intercept form, y = mx + b, we can write the equation of the line perpendicular to y = 3x + 7 as y = (-1/3)x + b.

To find the value of b, we substitute the point (x, y) = (0, 5) into the equation:

5 = (-1/3)(0) + b

5 = b

Therefore, the equation of the line perpendicular to y = 3x + 7 at x = 0 is y = (-1/3)x + 5.

limits for v are ([tex]\frac{x1864}{525}[/tex]) to ([tex]\frac{15u-12}{9}[/tex].

To evaluate the given integral using the transformation u = x + y and v = x + 4y, we need to find the

Jacobian

of the transformation and express the region R in terms of u and v.

Let's find the Jacobian first:

J = ∂(x, y) / ∂(u, v)

To do this, we need to find the

partial derivatives

of x and y with respect to u and v.

From u = x + y, we can express x in terms of u and v:

x = u - v

Similarly, from v = x + 4y, we can express y in terms of u and v:

v = x + 4y

v = (u - v) + 4y

v = u + 4y - v

2v = u + 4y

y = (u - 2v) / 4

Now, let's find the partial derivatives:

∂x/∂u = 1

∂x/∂v = -1

∂y/∂u = 1/4

∂y/∂v = -1/2

The Jacobian is given by:

J = (∂x/∂u * ∂y/∂v) - (∂y/∂u * ∂x/∂v)

J = (1 * (-1/2)) - (1/4 * (-1))

J = -1/2 + 1/4

J = -1/4

Now, let's express the region R in terms of u and v.

The lines that bound the region R in the xy-plane are:

y = -26x

y = -3x + 3

y = -x

y = -x - 2 + 9xy + 4y

We can rewrite these equations in terms of u and v using the

inverse transformation

:

x = u - v

y = (u - 2v) / 4

Substituting these values in the equations of the lines, we get:

(u - 2v) / 4 = -26(u - v)

(u - 2v) / 4 = -3(u - v) + 3

(u - 2v) / 4 = -(u - v)

(u - 2v) / 4 = -(u - v) - 2 + 9(u - 2v) + 4(u - 2v)

Simplifying these equations, we have:

u - 2v = -104(u - v)

u - 2v = -12(u - v) + 12

u - 2v = -u + v

u - 2v = -u + v - 2 + 9u - 18v + 4u - 8v

Further simplifying, we get:

104(u - v) = -u + v

12(u - v) = -u + v - 12

2u - 3v = -2u - 6v + 2u - 10v

Simplifying the above equations, we find:

105u - 103v = 0

15u - 9v = 12

v = (15u - 12) / 9

Now, let's evaluate the integral:

[tex]\int\limits^a_b {\int\limits^a_b {R 279xy^4y} \, dx dy} =\int\limits^a_b {\int\limits^a_b {D f(u,v) |J|} \, du dv}[/tex]

Substituting the values of x and y in terms of u and v in the integrand, we have:

[tex]279(u - v)(u - 2v)^4(u - 2v) |J|[/tex]

Since J = -1/4, we can simplify the expression:

[tex]-279(u - v)(u - 2v)^4(u - 2v) / 4[/tex]

The region D in the uv-plane is determined by the equations:

105u - 103v = 0

15u - 9v = 12

Solving these equations, we find the limits of integration for u and v:

u = (1232/525)

v = (1864/525)

Therefore, the integral becomes:

[tex]\int\limits^a_b {\frac{D -279(u - v)(u - 2v)^4(u - 2v)}{4} dudv}[/tex], where the

limits

of integration for u are (1232/525) to 1 and the limits for v are (1864/525) to (15u - 12) / 9.

The exact value of sin θ can be determined by using the Pythagorean identity and the given information that cos θ is equal to 3/4 in Quadrant IV. The simplified form of sin θ is -√7/4.

In Quadrant IV, the cosine value is positive (given as 3/4). To find the sine value, we can use the Pythagorean identity: sin^2 θ + cos^2 θ = 1.

Plugging in the given value of cos θ:

sin^2 θ + (3/4)^2 = 1.

Rearranging the equation and solving for sin θ:

sin^2 θ = 1 - (9/16),

sin^2 θ = 16/16 - 9/16,

sin^2 θ = 7/16.

Taking the square root of both sides:

sin θ = ± √(7/16).

Since we are in Quadrant IV, where the sine is negative, we take the negative sign:

sin θ = - √(7/16).

To simplify the radical, we can factor out the perfect square from the numerator and the denominator:

sin θ = - √(7/4) * √(1/4),

sin θ = - (√7/2) * (1/2),

sin θ = - √7/4.

Therefore, the exact value of sin θ, in simplest form, is -√7/4.

The appropriate substitution to evaluate the integral ∫x^2 cos(x) sin^4(x) dx is u = sin(x). This simplifies the integral to ∫u^2 sin^3(u) du, which can be evaluated using integration techniques or a table of integrals.

To evaluate the integral ∫x^2 cos(x) sin^4(x) dx, we can use the substitution u = sin(x).

First, we need to find the derivative of u with respect to x. Differentiating both sides of the equation u = sin(x) with respect to x gives du/dx = cos(x).

Next, we substitute u = sin(x) and du = cos(x) dx into the integral. The x^2 term becomes u^2 since x^2 = (sin(x))^2. The cos(x) term becomes du since cos(x) dx = du.

Therefore, the integral simplifies to ∫u^2 sin^3(u) du. We can now integrate this expression with respect to u.

Using integration techniques or a table of integrals, we can find the antiderivative of u^2 sin^3(u) with respect to u.

Once the antiderivative is determined, we obtain the solution of the integral by substituting back u = sin(x).

It is important to note that the choice of substitution is not unique and can vary depending on the integrand. In this case, substituting u = sin(x) simplifies the integral by replacing the product of cosine and sine terms with a single variable, allowing for easier integration.

The solution to the given initial value problem, dp/dt = 5pt, p(1) = 6, is p(t) = 6e^(2t^2-2).

To solve the differential equation, we begin by separating the variables. We rewrite the equation as dp/p = 5t dt. Integrating both sides gives us ln|p| = (5/2)t^2 + C, where C is the constant of integration.

Next, we apply the initial condition p(1) = 6 to find the value of C. Substituting t = 1 and p = 6 into the equation ln|p| = (5/2)t^2 + C, we get ln|6| = (5/2)(1^2) + C, which simplifies to ln|6| = 5/2 + C.

Solving for C, we have C = ln|6| - 5/2.

Substituting this value of C back into the equation ln|p| = (5/2)t^2 + C, we obtain ln|p| = (5/2)t^2 + ln|6| - 5/2.

Finally, exponentiating both sides gives us |p| = e^((5/2)t^2 + ln|6| - 5/2), which simplifies to p(t) = ± e^((5/2)t^2 + ln|6| - 5/2).

Since p(1) = 6, we take the positive sign in the solution. Therefore, the solution to the differential equation with the initial condition is p(t) = 6e^((5/2)t^2 + ln|6| - 5/2), or simplified as p(t) = 6e^(2t^2-2)

The area of region R is 3√3 - √3/3 square units.

To find the area of region R bounded by the parabola y = 4 - x^2 and the line y = 1 in the first quadrant, we need to find the points of intersection between the parabola and the line.

First, set y = 4 - x^2 equal to y = 1: 4 - x^2 = 1

Rearranging the equation, we have:x^2 = 3

Taking the square root of both sides, we get: x = ±√3

Since we are only considering the first quadrant, we take the positive value: x = √3.

Now, to find the area of region R, we integrate the difference of the two curves with respect to x from 0 to √3.

Area of R = ∫[0, √3] (4 - x^2 - 1) dx

Simplifying the integrand, we have: Area of R = ∫[0, √3] (3 - x^2) dx

Integrating term by term, we get: Area of R = [3x - (x^3/3)] evaluated from 0 to √3

Plugging in the limits, we have: Area of R = [3√3 - (√3)^3/3] - [3(0) - (0^3/3)] , Area of R = 3√3 - (√3)^3/3

Simplifying further, we get: Area of R = 3√3 - √3/3

The answer explains how to find the derivative of the given function and then determine the equation of the tangent line at a specific point. It involves finding the derivative using the limit definition and using the derivative to find the equation of a line.

To find the derivative of the function f(x) = lim (x→a) (-8x + 9), we need to apply the limit definition of the derivative. The derivative represents the rate of change of a function at a given point.

Using the limit definition, we can compute the derivative as follows:

f'(x) = lim (h→0) [f(x+h) - f(x)] / h,

where h is a small change in x.

After evaluating the limit, we can find f'(x) by simplifying the expression and substituting the value of x. This will give us the derivative function.

Next, to find the equation of the tangent line at the point (3, -6), we can use the derivative f'(x) that we obtained. The equation of a tangent line is of the form y = mx + b, where m represents the slope of the line.

At the point (3, -6), substitute x = 3 into f'(x) to find the slope of the tangent line. Then, use the slope and the given point (3, -6) to determine the value of b. This will give you the equation of the tangent line at that point.

By substituting the values of the slope and b into the equation y = mx + b, you will have the equation of the tangent line at the point (3, -6).

S, obtained by revolving the bounded region R enclosed by the curve y = x^2 - 2x and the x-axis about the x-axis, we can use the disk method. The volume of S can be obtained by integrating the cross-sectional areas of the disks formed by slicing R perpendicular to the x-axis.

The curve y = x^2 - 2x intersects the x-axis at x = 0 and x = 2. To apply the disk method, we integrate the area of each disk formed by slicing R perpendicular to the x-axis.

The cross-sectional area of each disk is given by A(x) = πr², where r is the radius of the disk. In this case, the radius is equal to the y-coordinate of the curve, which is y = x^2 - 2x.

To compute the volume, we integrate the area function A(x) over the interval [0, 2]:

V = ∫[0, 2] π(x^2 - 2x)^2 dx.

Expanding the squared term and simplifying, we have:

V = ∫[0, 2] π(x^4 - 4x^3 + 4x^2) dx.

Integrating each term separately, we obtain:

V = π[(1/5)x^5 - (1/4)x^4 + (4/3)x^3] |[0, 2].

Evaluating the integral at the upper and lower limits, we get:

V = π[(1/5)(2^5) - (1/4)(2^4) + (4/3)(2^3)] - π(0).

Simplifying the expression, we find:

V = π[32/5 - 16/4 + 32/3] = π[32/5 - 4 + 32/3].

Therefore, the volume of the solid S, obtained by revolving the bounded region R about the x-axis, using the disk method, is π[32/5 - 4 + 32/3].

The volume of the solid bounded below by the xy-plane, on the sides by p=18, and above by p=16 is 32π units cubed.

To find the volume of the solid, we need to integrate the function over the given region. In this case, the region is bounded below by the XY-plane, on the sides by p=18, and above by p=16.

Since the region is in polar coordinates, we can express the volume element as dV = p dp dθ, where p represents the distance from the origin to a point in the region, DP is the differential length along the radial direction, and dθ is the differential angle.

To integrate the function over the region, we set up the integral as follows:

V = ∫∫R p dp dθ,

where R represents the region in the polar coordinate system.

Since the region is bounded by p=18 and p=16, we can set up the integral as follows:

[tex]V = ∫[0,2π] ∫[16,18] p dp dθ.[/tex]

Evaluating the integral, we get:

[tex]V = ∫[0,2π] (1/2)(18^2 - 16^2) dθ[/tex]

[tex]= ∫[0,2π] (1/2)(324 - 256) dθ[/tex]

[tex]= (1/2)(324 - 256) ∫[0,2π] dθ[/tex]

To find the arc length, we need to integrate the expression √(1 + (dy/dx)²) with respect to x over the given interval. In this case, the given function is y = 3x²− (1/24) ln x.

The equation that models the trout population in terms of time is P = 1650[tex]e^{(-t/15)[/tex], the population after 17 days is approximately 1287.81, and according to this model, the trout population will never reach zero and will not completely die off.

(a) To find the equation that models the population P in terms of time t, we need to solve the differential equation:

dP/dt = [tex]-110e^{(-t/15)[/tex]

To do this, we can integrate both sides of the equation with respect to t:

∫ dP = ∫[tex]-110e^{(-t/15) }dt[/tex]

Integrating the right side gives us:

P = -110 ∫[tex]e^{(-t/15)}dt[/tex]

To integrate [tex]e^{(-t/15),[/tex] we can use the substitution u = -t/15:

du = (-1/15)dt

dt = -15du

Substituting these values into the equation, we get:

P = -110 ∫ [tex]e^{u[/tex] (-15du)

P = 1650[tex]e^{(-t/15)[/tex]+ C

Since we know that when t = 0, the population is 1650, we can substitute those values into the equation to solve for C:

1650 = 1650[tex]e^{(0/15)[/tex] + C

1650 = 1650 + C

C = 0

Therefore, the equation that models the population P in terms of time t is:

P = 1650[tex]e^{(-t/15)[/tex]

(b) To find the population after 17 days, we can substitute t = 17 into the equation:

P = 1650[tex]e^{(-17/15)[/tex]

P ≈ 1287.81

The population after 17 days is approximately 1287.81.

(c) According to the model, the entire trout population will die when P = 0. We can set up the equation and solve for t:

0 = 1650[tex]e^{(-t/15)[/tex]

Dividing both sides by 1650:

0 = [tex]e^{(-t/15)[/tex]

Taking the natural logarithm (ln) of both sides:

ln(0) = -t/15

Since the natural logarithm of 0 is undefined, there is no solution to this equation. Therefore, according to this model, the trout population will never reach zero and will not completely die off.

Therefore, the equation that models the trout population in terms of time is P = 1650[tex]e^{(-t/15)\\[/tex], the population after 17 days is approximately 1287.81, and according to this model, the trout population will never reach zero and will not completely die off.

The dimensions of the poster that will minimize the amount of paper used are 7 inches for the vertical height and 16 inches for the horizontal width.

We need to design a rectangular poster to fit 75 square inches of printing with a 6-inch margin at the top and bottom and a 2-inch margin on either side. This means the total area of the poster will be 75 + (6 x 2) x (2 x 2) = 99 square inches. To minimize the amount of paper used, we need to find the dimensions of the poster that will give us the smallest area. Let the vertical height of the poster be h and the horizontal width be w. Then we have h + 12 = w + 4  (since the total width of the poster is h + 4 and the total height is w + 12)75 = hw. We can solve the first equation for h in terms of w: h = w - 8 + 12 = w + 4. Substituting this into the second equation, we get:75 = w(w + 4)w² + 4w - 75 = 0w = (-4 ± √676)/2 = (-4 ± 26)/2 = 11 or -15The negative value doesn't make sense in this context, so we take w = 11.

Step-by-step explanation:

You need to either graph the equation or manipulate the equation into the standard form for a circle  ( often requiring 'completing the square' procedure)

circle equation:

        (x-h)^2 + (y-k)^2  = r^2    where (h,l) is the center   r = radius

x^2  - 6x      +     y^2 + 10 y  = 2    'complete the square for x and y

x^2 -6x +9    +     y^2 +10y + 25   = 2  + 9   + 25      reduce both sides

(x-3)^2           +  (y+5)^2    = 36     (36 is 6^2   so r = 6)

The derivative of f(x) = 5x sin(6x) is f'(x) = 2/x - 6sin(6x) and the derivative of f(x) = ln(2x) + cos(6x) is f'(x) = 2/x - 6sin(6x)

To obtain f'(x) for the function f(x) = 5x sin(6x) we will follow the following steps:

1. Apply the product rule.

Let u = 5x and v = sin(6x).

Then, using the product rule: (u*v)' = u'v + uv'

2. Obtain the derivatives of u and v.

u' = 5 (derivative of 5x with respect to x)

v' = cos(6x) * 6 (derivative of sin(6x) with respect to x)

3. Plug the derivatives into the product rule.

f'(x) = u'v + uv'

= 5 * sin(6x) + 5x * cos(6x) * 6

= 5sin(6x) + 30xcos(6x)

Therefore, f'(x) = 5sin(6x) + 30xcos(6x).

Now, let's obtain f'(x) for the function f(x) = ln(2x) + cos(6x):

1. Apply the sum rule and chain rule.

f'(x) = (ln(2x))' + (cos(6x))'

2. Obtain the derivatives of ln(2x) and cos(6x).

(ln(2x))' = (1/x) * 2 = 2/x

(cos(6x))' = -sin(6x) * 6 = -6sin(6x)

3. Combine the derivatives.

f'(x) = 2/x - 6sin(6x)

Therefore, f'(x) = 2/x - 6sin(6x).
