Answers
To achieve the least area, create two separate square enclosures, each with a side length of 25 m. For the greatest area, make one enclosure with a side length of 49 m and another with a side length of 1 m.
To determine the plans for the least and greatest areas using 200 m of fencing, we'll consider two cases: one square enclosure and two square enclosures.
Case 1: One square enclosure
Perimeter = 200 m
Since the perimeter of a square is 4 * side length (s), we have:
200 = 4 * s
s = 50 m
Area of one square enclosure = s^2 = 50^2 = 2500 m^2
Case 2: Two square enclosures
Let s1 and s2 be the side lengths of the two square enclosures.
Perimeter = 200 m
4 * (s1 + s2) = 200
s1 + s2 = 50
Since the area of a square is side length squared, we have:
Area = s1^2 + s2^2
To minimize the area, make the side lengths equal:
s1 = s2 = 25 m
Minimum area = 2 * (25^2) = 2 * 625 = 1250 m^2
To maximize the area, make one side length as large as possible while keeping the perimeter constraint:
s1 = 49 m, s2 = 1 m
Maximum area = 49^2 + 1^2 = 2401 + 1 = 2402 m^2
Therefore, to achieve the least area, create two separate square enclosures, each with a side length of 25 m. For the greatest area, make one enclosure with a side length of 49 m and another with a side length of 1 m.

You add 4 drops of food coloring to 2 cups of white frosting and get the orange frosting above. Francisco wants his frosting to be the same color as yours, but he has 5 cups of white frosting. He doesn't know how many drops of orange food coloring to add.
Answers
Answer:
Francisco will add 10 drops of food coloring to 5 cups of white frosting and get the orange frosting
Step-by-step explanation:
4 drops of food coloring to 2 cups of white frosting and get the orange frosting.
He has 5 cups of white frosting. He doesn't know how many drops of orange food coloring to add
Let x = drops of food coloring he will add
Drops of food coloring : cups of white frosting
4 : 2 = x : 5
4 / 2 = x / 5
Cross multiplication
4 * 5 = 2 * x
20 = 2x
Divide both sides by 2
x = 20 / 2
= 10
x = 10 drops of food coloring
Therefore, Francisco will add 10 drops of food coloring to 5 cups of white frosting and get the orange frosting

true or false: y=x³-4 is a linear equation
Answers
Answer: false
Step-by-step explanation:
linear equations do not have x's with exponents
Consider the initial-value problem y' = sqrt(1 − y^2), y(0) = 0. a. Show that y = sin x is the solution of this initial-value problem. b. Look for a solution of the initial-value problem in the form of a power series about x = 0. Find the coefficients up to the term in x^3 in this series.
Answers
We have shown that when y = sin(x), the differential equation y' = sqrt(1 - y^2) is satisfied. Additionally, y(0) = 0 is also satisfied when x = 0. Hence, y = sin(x) is the solution to the given initial-value problem.
1. The given initial-value problem is y' = sqrt(1 - y^2), y(0) = 0. To show that y = sin(x) is the solution, we differentiate sin(x) to find its derivative, which is cos(x). Substituting y = sin(x) into the differential equation, we get cos(x) = sqrt(1 - sin^2(x)). Simplifying this equation using the trigonometric identity cos^2(x) + sin^2(x) = 1, we find that cos(x) = cos(x). Since the equation is satisfied, y = sin(x) is indeed a solution to the initial-value problem.
2. To verify that y = sin(x) is a solution to the initial-value problem y' = sqrt(1 - y^2), y(0) = 0, we start by differentiating sin(x). The derivative of sin(x) is cos(x).
3. Next, we substitute y = sin(x) into the differential equation y' = sqrt(1 - y^2). This gives us cos(x) = sqrt(1 - sin^2(x)). We simplify the right side of the equation using the trigonometric identity cos^2(x) + sin^2(x) = 1. This identity allows us to rewrite the equation as cos(x) = sqrt(cos^2(x)).
4. Since cos(x) is always positive or zero, we can take the square root of both sides without changing the equation. This results in cos(x) = cos(x), which is true for all values of x. Therefore, we have shown that when y = sin(x), the differential equation y' = sqrt(1 - y^2) is satisfied. Additionally, y(0) = 0 is also satisfied when x = 0. Hence, y = sin(x) is the solution to the given initial-value problem.

set up, but do not evaluate, an integral for the area of the surface obtained by rotating the curve about the x-axis and the y-axis. y = xe−x, 3 ≤ x ≤ 5
Answers
The integral for the area of the surface obtained by rotating the curve about the x-axis and the y-axis, are:
S = ∫[3,5] 2πxe−x√(1+(e−x−xe−x)²)dx and S = ∫[3e−3,5e−5] 2π(ln(y)/y)√(1+(1/y−ln(y)/y)²)dy respectively.
To set up the integral for the area of the surface obtained by rotating the curve about the x-axis and the y-axis, we need to use the formulas for surface area of revolution.
For rotation about the x-axis, the formula is:
S = ∫2πy√(1+(dy/dx)²)dx
For rotation about the y-axis, the formula is:
S = ∫2πx√(1+(dy/dx)²)dy
Plugging in the given curve y = xe−x and the bounds 3 ≤ x ≤ 5, we get:
For rotation about the x-axis:
S = ∫[3,5] 2πxe−x√(1+(e−x−xe−x)²)dx
For rotation about the y-axis:
S = ∫[3e−3,5e−5] 2π(ln(y)/y)√(1+(1/y−ln(y)/y)²)dy
These are the integrals that need to be evaluated to find the area of the surface obtained by rotating the curve about the x-axis and the y-axis.

Find an expression for the slope, s, of the graph of Q (on the vertical axis) vs. V (horizontal axis). Start with C=VQ. You do not need any data points to do this.

Answers
1. The slope (s) of the graph of C vs. A is ε₀. 2. The slope (s) of the graph of C vs. d₁ is ε₀A. 3. The slope (s) of the graph of Q vs. V is Q.
1. To find the expression for the slope (s) of the graph of C (on the vertical axis) vs. A (horizontal axis) when starting with C = dε₀A, we can use the concept of differentiation.
Differentiating both sides of the equation with respect to A, we have:
dC/dA = d(dε₀A)/dA
Since dε₀A/dA equals ε₀, we can simplify the equation as follows:
dC/dA = dε₀A/dA = ε₀
Therefore, the slope (s) of the graph is equal to ε₀.
2. To find the expression for the slope (s) of the graph of C (on the vertical axis) vs. d₁ (horizontal axis) when starting with C = dε₀A, we again use differentiation.
Differentiating both sides of the equation with respect to d₁, we have:
dC/dd₁ = d(dε₀A)/dd₁
Since dε₀A/dd₁ equals ε₀A, we can simplify the equation as follows:
dC/dd₁ = ε₀A
Therefore, the slope (s) of the graph is equal to ε₀A.
3. To find the expression for the slope (s) of the graph of Q (on the vertical axis) vs. V (horizontal axis) when starting with C = VQ, we can use the concept of differentiation.
Differentiating both sides of the equation with respect to V, we have:
dC/dV = d(VQ)/dV
Using the power rule of differentiation, where d(x^n)/dx = nx^(n-1), we can simplify the equation:
dC/dV = Q
Therefore, the slope (s) of the graph is equal to Q.
In summary:
1. The slope (s) of the graph of C vs. A is ε₀.
2. The slope (s) of the graph of C vs. d₁ is ε₀A.
3. The slope (s) of the graph of Q vs. V is Q.

Water is poured into the top half of a spherical tank at a constant rate. If W(t) is the rate of increase of the depth of the water, then W is: O constant O linear and increasing O linear and decreasing O concave up
Answers
The rate of increase of the depth of the water (W(t)) is constant.
What is rate ?
In mathematics and physics, the rate is a measure of change of a certain quantity with respect to another quantity. The rate can be a number, a ratio or a derivative. It is often represented by the symbol "d" or "dx/dt" or "dy/dt" and it measures how fast a quantity is changing.
Water is poured into the top half of a spherical tank at a constant rate, this means that the rate of increase of the depth of the water (W(t)) is constant.
In this case, W(t) is constant.
It is important to keep in mind that the rate of change of the function doesn't indicate the shape of the function, it just tells us the change of the dependent variable with respect to the independent variable. The shape of the function can be visualized by creating a graph of the function.
So , The rate of increase of the depth of the water (W(t)) is constant.

Answers
To calculate Nathan's net worth, we need to determine his total liabilities (debt) and subtract that from his total assets. The debt ratio tells us that Nathan's liabilities are 80% of his total net worth.
Total liabilities = Car loan + Mortgage + Student loans = $2,000 + $150,000 + $15,000 = $167,000
Nathan's net worth = Total assets = Total liabilities / Debt ratio = $167,000 / 0.8 = $208,750

a quadratic function f is given. f(x) = x2 − 12x 24 (a) express f in standard form f(x) =
(b) Sketch a graph of f.
Answers
The x-intercepts are approximately 0.54 and 11.46. Since the coefficient of x^2 is positive, the graph opens upwards. Combining all of this information, we can sketch a graph of f(x) that looks like a "U" shape with vertex at (6, -12) and x-intercepts at approximately 0.54 and 11.46.
(a) To express f(x) in standard form, we need to complete the square. First, we can factor out the coefficient of x^2 to get:
f(x) = x^2 - 12x + 24
Next, we add and subtract (12/2)^2 = 36 to the expression inside the parentheses to get:
f(x) = (x^2 - 12x + 36) - 36 + 24
The expression inside the parentheses can be rewritten as (x - 6)^2, so we have:
f(x) = (x - 6)^2 - 12
Therefore, the standard form of the quadratic function f(x) is f(x) = (x - 6)^2 - 12.
(b) To sketch a graph of f, we can first identify the vertex as (6, -12) from the standard form. This is the lowest point on the graph since the coefficient of x^2 is positive. We can also find the x-intercepts by setting f(x) = 0:
(x - 6)^2 - 12 = 0
(x - 6)^2 = 12
x - 6 = ±√12
x = 6 ± 2√3.
