Answer:

w=17.613

l=15.613

Step-by-step explanation:

w×l=area

l=w-2

therefore w×(w-2)=575

rearrange the equation to make a quadratic

(w^2)-2w-575=0

w=-(b+ or - sqrt (b^2-4ac))/2a

a=1

b=-2

c=-575

using quadraric formula to solve

w=17.613 or -15.613

cant be -15.613

l=w-2

=15.613

When the length and width of a rectangle change by a factor of 6, the area of the rectangle changes by a factor equal to the product of the changes in length and width. Since both the length and width are multiplied by 6, the area will be multiplied by 6 * 6, which is equal to 36.

This means that the area of the rectangle will increase by a factor of 36. In other words, the new area will be 36 times larger than the original area. This is because the area of a rectangle is calculated by multiplying the length by the width, so when both dimensions are multiplied by 6, the resulting area is the product of 6 * 6, which is 36 times larger than the original area.

For example, if the original area of the rectangle was 10 square units, after the change, the new area will be 10 * 36 = 360 square units. Therefore, the area of the rectangle is significantly increased when both the length and width are multiplied by the same factor.

The value of the integral (x² + y²)dA over the triangle T is 1/3.

To evaluate the expression (x² + y²)dA over the triangle T, we need to set up a double integral over the region T.

The triangle T can be defined by the following bounds:

0 ≤ x ≤ 1

0 ≤ y ≤ x

Thus, the integral becomes:

∫∫T (x² + y²) dA = ∫₀¹ ∫₀ˣ (x² + y²) dy dx

We will integrate first with respect to y and then with respect to x.

∫₀ˣ (x² + y²) dy = x²y + (y³/3) |₀ˣ

= x²(x) + (x³/3) - 0

= x³ + (x³/3)

= (4x³/3)

Now, we integrate this expression with respect to x over the bounds 0 ≤ x ≤ 1:

∫₀¹ (4x³/3) dx = (x⁴/3) |₀¹

= (1/3) - (0/3)

= 1/3

Therefore, the value of the integral (x² + y²)dA over the triangle T is 1/3.

The areas of the sectors are:

For an arc length of 2π, the area of the sector is 6π square units.

For an arc length of 3π, the area of the sector is 9π square units.

For an arc length of 4π, the area of the sector is 6π square units.

For an arc length of π, the area of the sector is 3π/2 square units.

The total circumference of the circle is given by:

C = 2πr = 2π(6) = 12π

The total area of the circle is given by:

A = πr^2 = π(6^2) = 36π

To find the area of a sector, we need to know the central angle θ that defines the arc length. The central angle θ is measured in radians and is related to the arc length s and the radius r by the formula:

θ = s/r

So, the area of the sector is given by:

A_sector = (θ/2π)A

where A is the total area of the circle.

Let's find the area of the sector for different arc lengths:

For an arc length of s = 2π, the central angle is:

θ = s/r = 2π/6 = π/3

The area of the sector is:

A_sector = (π/3)/(2π) * 36π = 6π

For an arc length of s = 3π, the central angle is:

θ = s/r = 3π/6 = π/2

The area of the sector is:

A_sector = (π/2)/(2π) * 36π = 18π/2 = 9π

For an arc length of s = 4π, the central angle is:

θ = s/r = 4π/6 = 2π/3

The area of the sector is:

A_sector = (2π/3)/(2π) * 36π = 12π/2 = 6π

For an arc length of s = π, the central angle is:

θ = s/r = π/6

The area of the sector is:

A_sector = (π/6)/(2π) * 36π = 3π/2

So, the areas of the sectors are:

For an arc length of 2π, the area of the sector is 6π square units.

For an arc length of 3π, the area of the sector is 9π square units.

For an arc length of 4π, the area of the sector is 6π square units.

For an arc length of π, the area of the sector is 3π/2 square units.

The population growth of Farmville was approximately 100-141%

For the population growth of Farmville, we need to calculate the percentage increase from 1950 to 2000.

First, We find the absolute increase in population:

25,370 - 10,520 = 14,850

Next, the percentage increase:

(14,850 / 10,520) x 100 = 141%

So, the population of Farmville grew by approximately 141% from 1950 to 2000.

Alternatively, we can also use the rule of 70 to estimate the population growth.

The rule of 70 states that if a quantity grows at a constant rate, it will double in size approximately every 70 divided by the growth rate.

In this case, the population growth rate can be calculated as:

ln(25,370/10,520)/50 = 0.025

So the population of Farmville grew at a rate of approximately 2.5% per year. Using the rule of 70, we can estimate the number of years it took for the population to double:

70 / 2.5 = 28

So the population of Farmville doubled approximately every 28 years. This means that the population would have doubled once between 1950 and 2000, resulting in a growth rate of around 100%.

Therefore, both methods suggest that the population growth of Farmville was , 100-141%

Step-by-step explanation:

The optimal allocation of funds for the manufacturing firm is $30,000 on labor and $30,000 on materials. This will result in the maximum monthly output of the firm, which is $3,600.

The manufacturing firm has allocated $60,000 per month for labor and materials. To find the allocation that will result in the maximum output, we need to find the value of X and Y such that the monthly output is the highest.

The monthly output of the manufacturing firm in terms of x and y is given by

N(x,y) = 4xy−8x.

Let X thousand dollars be allocated to labor and Y thousand dollars to materials. Then,

X+Y = 60

Now, we will find the maximum value of N. We have

N(x,y) = 4xy - 8x

Substituting the value of Y in terms of X, we get:

N(X) = 4X(60-X) - 8X

=> N(X) = -4X^2 + 240X

Now, we will differentiate N(X) w.r.t. X:

dN(X)/dX = -8X + 240

Since we want to find the maximum value of N, we need to find the value of X, for which

dN(X)/dX = 0

dN(X)/dX = 0

=> -8X + 240 = 0

=> X = 30

Hence, the optimal allocation is $30,000 on labor and $30,000 on materials.

Thus, the maximum value of N is:

N(30) = -4(30)^2 + 240(30)

N(30) = $3600

Therefore, the optimal allocation of funds for the manufacturing firm is $30,000 on labor and $30,000 on materials. This will result in the maximum monthly output of the firm, which is $3,600.
