a wire of length 38 m is divided into two pieces and each piece is bent into a square. how should this be done in order to minimize the sum of the areas of the two squares? (give your answer in the form of a comma separated list of the lengths of the two pieces.)

Answers

The lengths of the two pieces of a wire will be 19,19.

Define square.

A square is a closed, two-dimensional object with four equal sides and four vertices. On either side, it has parallel sides.

The square of a square's side determines its area.

Given data -

Length of a wire = 38 m

As the wire is divided into two pieces,

Let the length of two pieces of wire be x and y m respectively.

As per given data, x + y = 38

Therefore, y = 38 - x    

As each piece is bent into a square, area of squares will be

\((x/4)^{2}\)  and  \((y/4)^{2}\)

Therefore, the sum of areas of two squares will be A = \((x/4)^{2}\) +      \((y/4)^{2}\)

A = \(x^{2}\)/16 + \(y^{2}\)/16

A = \(x^{2}\)/16 + \((38-x)^{2}\)/16

By differentiating, we will get

A' = \(\frac{2x}{16}\) - \(\frac{2(38-x)}{16}\)

In order to minimize the the sum of the areas of the two squares, we will take A' = 0

0 = x - (38 - x)

2x = 38

x = 19

Therefore y = 19

The length of two pieces of a wire should be 19 m each.

Step-by-step explanation:

perimeter =5x. where x is the side length

solve differential equation dy/dx=y^2 . 16y(2)=0

Answers

The particular solution corresponding to the initial condition 16y(2) = 0 (which I assume means y(2) = 0), we can plug x = 2 and y = 0 into the equation:
-1/0 = 2 + C

To solve the differential equation dy/dx=y^2, we can separate the variables and integrate both sides.
dy/y^2 = dx

Integrating both sides:
-1/y = x + C

where C is the constant of integration. Solving for y:
y = -1/(x+C)

To solve the second part of the question, 16y(2) = 0, we substitute y(2) into the equation we just found:
y(2) = -1/(2+C)
16y(2) = 16*(-1/(2+C)) = -16/(2+C) = 0

Solving for C:
-16 = 0*(2+C)

Thus, C can be any value since 0 multiplied by any number is 0. Therefore, the solution to the differential equation dy/dx=y^2 and the equation 16y(2)=0 is y = -1/(x+ C), where C is any constant.

Answers

the total amount of money that jayden made when both paychecks were the same is $99.45

To determine the number of hours Jayden worked the week his paycheck was the same for both jobs, we can solve an equation. The equation we'll use is 14.86h + 17.10 = 99.45. We can subtract 17.10 from both sides, leaving 14.86h = 82.35. Then we cane b divide both sides of the equation by 14.86, which will give us the result of h = 5.55 hours. The total amount of money that Jayden made when both paychecks were the same is 99.45. This can be confirmed by combining his earnings for both jobs, which would be 9.64h + 82.35 + 14.86h + 17.10 = 99.45.

Jayden worked 5.55 hours in the week his paycheck was the same for both jobs, and he earned a total of $99.45.

How do you find the domain and range of a square root of a quadratic function?.

Answers

Domain and range of a square root of a quadratic function is as [ 0, ∞ ) , and  [ 0 ,∞ ) respectively which is find by simplification.

Let us consider a square root quadratic function y = √x.

Domain of a square root quadratic function is :

All input values of x are domain of a function.

y = √x

⇒ x = y²

⇒ x ≥ 0

All the input values representing the domain are x > 0.

This implies domain is [0 , ∞ ).

And range of a square root quadratic function is:

All output values of y are range of a function.

y = √x

As we know x = y²

√y² = y > 0 .

Range is [ 0, ∞ ).

Therefore, domain and range of square root of a quadratic function is calculated by simplifying the function.

The equation of slope intercept form is  y =−4x+24

An intercept is a y-axis point through which the slope of a line passes. It is the y-coordinate of a y-axis point at which a straight line or a curve intersects. This is represented by the straight-line equation y = mx+c, where m is the slope and c is the y-intercept.

Given m = -4 and point)-3, -12)

One way to write a line's equation is in slope-intercept form, which looks like this:

y = mx+b

m = slope

b = y-intercept (where the line crosses the y-axis)

The problem has already been given

m = −4

x=-3

y=-12

Normally, the equation of a line is left with x and y being variables, and m and b having values. Since we do not have a value for b, we will plug all those numbers in and solve.

When those are substituted, the equation should look like this.

-12=(4)(-3)+b

-12=12+b

24=b

So the line's equation would be:

y=−4x+24

And this is your equation graphed. Notice how the line crosses the y-axis at 24, and that the slope is −4, just like the equation says.

A number line is a horizonal line in which we can represent all our real numbers.

According to the given question without using a calculator we have to determine locations of √73, 3π and \(7.\overline{81}\) on the number line.

For √73 we know, √64 is 8 and √81 is 9 so √73 lies between 8 and 9 on the number line and more closer to √81 as the distance between √73 and √81 is less than √64 and √73.

For 3π we know, π ≈ 3.14 so 3 times of 3 is 9 and 3 times of 14 is 42 so 3 times of .14 is .42 so it is 9 + .42 = 9.42.So it will lie between 9 and 10 and a just closer to 9 than 10.

Step 1: we will simplify both sides of the equation

16d + 2/3 = (14)(d) + (14)(−2)

16d + 2/3 = 14d + −28

16d + 2/3 = 14d - 28

Step 2: we need to subtract 14d on both sides

16d + 2/3 - 14d = 14d - 28 - 14d

2d + 2/3 = -28vide both

Step 3: we will subtract 2/3 from both sides

2d + 2/3 - 2/3 = -28 - 2/3

2d = -86/3

Step 4: Divide both side by 2

2d/2 = d

-86/3/2 = -43/3

This process may lead to a quadratic equation that needs to be solved, resulting in multiple x-values. These x-values will correspond to the points on the graph of y = f(x) where the tangent line passes through (1, -1).

To find the points on the graph of y = f(x) where the tangent line passes through the point (1, -1), we need to find the x-values that satisfy this condition.

First, we need to find the derivative of the function f(x). The derivative of f(x) = 3x^2 - 4x + 3 is f'(x) = 6x - 4.

Now, let's find the slope of the tangent line passing through the point (1, -1). We can use the point-slope form of a line, which is given by y - y1 = m(x - x1), where (x1, y1) is the point on the line and m is the slope of the line.

Substituting the values (1, -1) into the equation, we get y - (-1) = (6x - 4)(x - 1). Simplifying this equation, we have y + 1 = 6x^2 - 10x - 4.

To find the x-values that satisfy this equation, we can substitute f(x) into y. So, y + 1 = 6(f(x)) - 10x - 4. Substituting f(x) = 3x^2 - 4x + 3, we have y + 1 = 6(3x^2 - 4x + 3) - 10x - 4.

Now, we can simplify the equation and solve for x to find the x-values for which the tangent line passes through (1, -1).

This process may lead to a quadratic equation that needs to be solved, resulting in multiple x-values. These x-values will correspond to the points on the graph of y = f(x) where the tangent line passes through (1, -1).

Likewise a 50% increase correlates to multiply by 1.5

Since we are trying to find the previous amount that experienced the increase, we divide by 1.5 to find the original amount because that amount*1.5 gives us 279.

If land costs $100. 00 per square foot, what is the cost of. 21 acres

Answers

The cost of 0.21 acres of land would be $914,060.00 if the land is measured in square meters and the cost per square foot is $100.00.

There are different ways to approach this problem depending on the units of measurement. Here are a few possible ways to solve the problem:

If the land is measured in square feet:

1 acre = 43,560 square feet (by definition)

0.21 acres = 0.21 x 43,560 = 9,131.6 square feet

Cost of 9,131.6 square feet at $100.00 per square foot = $913,160.00

Therefore, the cost of 0.21 acres of land would be $913,160.00 if the land is measured in square feet.

If the land is measured in square meters:

1 acre = 4,046.86 square meters (by definition)

0.21 acres = 0.21 x 4,046.86 = 849.0446 square meters

1 square meter = 10.7639 square feet (approximately)

849.0446 square meters = 9,140.6 square feet (approximately)

Cost of 9,140.6 square feet at $100.00 per square foot = $914,060.00

Therefore, the cost of 0.21 acres of land would be $914,060.00 if the land is measured in square meters and the cost per square foot is $100.00.
