The Newton-Raphson algorithm is used to find the root of the equation \(e^{-x^2}\) - \(x^3\) = 0. Three iterations are performed from the starting point x₀ = 1. The estimated root is 0.806553.

The Newton-Raphson algorithm is an iterative method used to find the root of an equation. It involves repeatedly improving an initial guess by using the formula:

xᵢ₊₁ = xᵢ - f(xᵢ)/f'(xᵢ),

where xᵢ is the current approximation, f(xᵢ) is the function value at xᵢ, and f'(xᵢ) is the derivative of the function at xᵢ.

To apply the algorithm to the equation \(e^{-x^2}\) - \(x^3\)= 0, we need to find the derivative of the function. Taking the derivative of \(e^{-x^2}\) gives -2x *\(e^{-x^2}\), and the derivative of \(x^3\) is 3\(x^{2}\).

Starting from x₀ = 1, we can perform three iterations of the Newton-Raphson algorithm to approximate the root. After each iteration, we update the value of x based on the formula mentioned above.

After three iterations, we find that the estimated root is approximately 0.806553.

To estimate the error, we can calculate the difference between the estimated root and the actual root. In this case, the actual root is given as 0.806553. The error can be obtained by taking the absolute value of the difference between the estimated root and the actual root.

Typically, an infant who is 24-hours-old would need to consume around 2-3 ounces of formula per feeding to meet their daily caloric needs on a 4-hour feeding schedule. However, it's important to note that every baby is different and may require more or less formula depending on their individual needs and growth.

To determine the recommended ounces of formula for a 24-hour-old infant on a 4-hour feeding schedule, we need to consider the infant's daily caloric needs. Here's a step-by-step explanation:
1. An average newborn infant requires around 100-120 calories per kilogram (2.2 pounds) of body weight per day.
2. Assuming an average newborn weight of 3.5 kg (7.7 lbs), the infant would need 350-420 calories per day (3.5 kg x 100-120 calories/kg).
3. Formula generally provides around 20 calories per ounce.
4. Divide the total daily caloric needs by the calories per ounce: 350-420 calories ÷ 20 calories/ounce = 17.5-21 ounces of formula per day.
5. Since the infant is on a 4-hour feeding schedule, they will have 6 feedings per day (24 hours ÷ 4 hours/feeding).
6. Divide the total daily ounces by the number of feedings: 17.5-21 ounces ÷ 6 feedings = 2.9-3.5 ounces per feeding.
So, a newborn infant who is 24-hours-old on a 4-hour feeding schedule should receive approximately 2.9-3.5 ounces of formula at each feeding to meet their daily caloric needs.

Answer:

85 ft.

Step-by-step explanation:

8*10=80 (the value of the the rectangle by itself)

then we take the values we are given and find the width and height of the triangle. Knowing it is a right triangle, we perform two equations,

15-10 (the total length of the polygon) 5 ft

and

8-6 (to find the height of the triangle, using the length where the hypotenuse of the triangle cuts off the rectangle) 2 ft

With this, we now have the length and width of the right triangle, and multiply them together to get 10. Because that formula only works on rectangles and squares, but we know that the triangle is a right triangle, we divide the 10 in half to get 5, which is the area of the triangle. Together, the value of the area for the rectangle and the triangle together result in 85 ft (remember to label units when in a written test!)

Step-by-step explanation:

We can set up an equation for this line using slope intercept form:

\(y = mx + b\)

Where \(m\) is the slope of the line and \(b\) is the y-intercept (where the line cross the Y-axis at \(x = 0\)).

We know that the slope of the line is \(-4\) so we can plug that in for \(m\), but we don't know \(b\), so we'll have to use the given point \()(-6, -10)\) to help solve for it:

\(y = -4x + b\)

\(-10 = -4(-6) + b\)

\(-10 = 24 + b\)

\(b = -34\)

This means the equation of the line is \(y = -4x - 34\). Now we can plug in the point \((-9, s)\) and solve for \(s\):

\(y = -4x - 34\)

\(s = -4(-9) - 34\)

\(s = 36 - 34\)

\(s = 2\)

Step-by-step explanation:

The new price was:Selling price after first markdown = 0.8 x 540 = $432The table was marked down again by 30%. Therefore, the final selling price was:Selling price after second markdown = 0.7 x 432 = $302.40Final reduced price of the table = $302.40

Let the cost of the baseball be x dollars. A markup of 40% on the selling price means that the selling price is 140% of the cost.Selling price = Cost + MarkupSelling price = x + 0.4xSelling price = 1.4xMarkup = Selling price - CostMarkup = 1.4x - xMarkup = 0.4xCost of baseball = x dollarsSelling price of baseball = 1.4x dollars4. If a DVD player is marked up by 50% based on cost, then the selling price is 150% of the cost. Let the cost of the DVD player be x dollars. Therefore, the selling price of the DVD player is:Selling price = Cost + MarkupSelling price = x + 0.5xCost is 100% of the cost, and selling price is 150% of the cost. The markup rate based on the selling price is:Markup rate based on selling price = Markup/ Selling priceMarkup rate based on selling price = (Selling price - Cost)/Selling priceMarkup rate based on selling price = 0.5x/1.5xMarkup rate based on selling price = 1/3 = 33.33%5. A bag is priced at $40. The price is reduced by $20, so the new price is $40 - $20 = $20.The amount of markdown is the difference between the original price and the reduced price.Amount of markdown = Original price - Reduced priceAmount of markdown = $40 - $20Amount of markdown = $206. The table was marked up by 80% based on cost. Therefore, the selling price was 180% of the cost.Selling price = 1.8 x 300 = $540The table was then marked down by 20%.

3. Markup based on selling price is given by the formula:

Markup based on selling price = (Markup/ Selling price) × 100 Markup = 40 %

So, Markup based on selling price = (40/ 100) × Selling price => Markup based on selling price = 0.4

Selling price + Markup = Cost + Selling price Markup = Selling price × 0.4

Given, Markup = $20$20 = Selling price × 0.4

Selling price = $20/0.4 = $50

Therefore, Cost = Selling price - Markup = $50 - $20 = $30.

The cost and selling price of a baseball that is marked up $ 20 with a 40 % markup based on the selling price are $30 and $50 respectively.

4. The conversion formula from markup rate based on cost to markup rate based on selling price is given as:

Markup based on selling price = (Markup/ Cost + Markup) × 100

Markup based on cost = (Markup/ Cost) × 100

Let's say the markup rate based on cost is x %.

So, Markup based on cost = x%

Markup based on selling price = 50%

So, using the conversion formula:

50 = (x/100 + x) × 100=> 50 = x(1 + x/100)=> 50 = x + (x2/100) => x2 + 100x - 5000 = 0=> (x - 50)(x + 100) = 0

The possible solutions are: x = 50% (which is valid) or x = -100% (which is not valid).

Therefore, the markup rate based on selling price of the DVD player is 50%.

5. The amount of markdown can be calculated as follows:

Markdown = Original price - Reduced price

Original price = $40

Reduced price = $40 - $20 = $20

Markdown = $40 - $20 = $20

Therefore, the amount of markdown is $20.6.

The table was bought for $300 and was marked up by 80% based on the cost.

So, the selling price of the table was:

Selling price = Cost + Markup

Markup = 80% of $300 = $240

Selling price = $300 + $240 = $540

Now, the table was marked down by 20% for a promotion, which gives a new selling price:

Selling price after 20% markdown = Selling price - 20% of Selling price= $540 - 20% of $540= $540 - $108= $432

Now, the table is marked down again by 30%, which gives the final reduced price:

Selling price after 30% markdown = Selling price - 30% of Selling price= $432 - 30% of $432= $432 - $129.6= $302.4

Therefore, the final reduced price of the table is $302.4.

The first-order system of equations:x1' = x2, x2' = 3x2 - 7x1 + \(t^2\)

To convert the nonhomogeneous differential equation y′′ + 3y′ + 7y = \(t^2\) to a first order system, we can define two new variables, x1 = y and x2 = y′.

Then, we can express the derivatives of x1 and x2 in terms of themselves and t:

x1' = y' = x2

x2' = y'' = t^2 - 3y' - 7y

Now, we have a system of two first-order differential equations:

x1' = x2

x2' = t^2 - 3x2 - 7x1

We can rewrite this system in matrix form:

[x1']   [0 1][x1]   [0]

[x2'] = [7 -3][x2] + \(t^2\)

where the matrix on the left-hand side is the coefficient matrix, the column vector on the right-hand side contains the forcing functions, and the column vector on the left-hand side contains the derivatives of x1 and x2.

Thus, the first order system for the nonhomogeneous differential equation y′′ + 3y′ + 7y = \(t^2\) is:

[x1'] = [0 1][x1]

[x2']   [7 -3][x2] + \(t^2\)
To convert the nonhomogeneous differential equation y'' - 3y' + 7y =\(t^2\) to a first-order system, let x1 = y and x2 = y'. Then, we have:

x1' = y' = x2
x2' = y'' = 3y' - 7y + \(t^2\)

Now, substitute the expressions for x1 and x2:

x1' = x2
x2' = 3x2 - 7x1 + \(t^2\)

This gives us a first-order system of equations:

x1' = x2
x2' = 3x2 - 7x1 +\(t^2\)

Using proportions, the number of pounds that will be needed for a single serving is: one and three seventh pounds.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The number of pounds for 3 people is given by:

\(3 \frac{3}{7} = 3 + \frac{3}{7} = \frac{24}{7}\)

Hence, for one person, the number of pounds can be divided by three(multiplied by 1/3), hence:

\(\frac{24}{7} \times \frac{1}{3} = \frac{24}{21}\)

24 divided by 21 has a quotient of 1 and remainder of 3, hence as a mixed number, the amount is:

She must buy 90 tiles for the cost to be the same at both stores

Step-by-step explanation:

Let x be the no. of tiles bought for the cost to be the same at both stores

Margo can purchase tile at a store for $0.89 per tile at shop 1

Cost of x tiles =0.89x

She rent a tile saw for $45.

So, total cost at Store 1 = 0.89x+45

At another store she can borrow the tile saw for free if she buys tiles there for $1.39 per tile.

So, cost of 1 tile = 1.39

Cost of x tiles = 1.39x

ATQ

0.89x+45=1.39x

45=1.39x-0.89x

45=0.5x

\(\frac{45}{0.5}=x\)

90=x

Hence She must buy 90 tiles for the cost to be the same at both stores

The two points where the line meets the circle are (3,6) and (8,3).

To find the coordinates of the point where the line 2x+2y=18 meets the circle (x-2)^2+(y-3)^2=16, we need to first solve the system of equations.

We can start by simplifying the equation of the line by dividing both sides by 2, giving us x+y=9. We can then substitute y=9-x into the equation of the circle,

which results in (x-2)^2+(9-x-3)^2=16. Simplifying this equation yields x^2-4x+4+x^2-12x+81=16. Combining like terms and solving for x, we get x=3 or x=8.

The vertex of the Quadratic function with a y-intercept of (5, 0) and an x-intercept of (0, 80) is located at the point (0, 0).

The vertex of a quadratic function given the y-intercept and x-intercept, we need to determine the axis of symmetry, which is the line that passes through the vertex. The x-coordinate of the vertex will be the midpoint between the x-intercepts, while the y-coordinate will be the same as the y-intercept.

Given that the y-intercept is (5, 0) and the x-intercept is (0, 80), we can determine the x-coordinate of the vertex by finding the midpoint of the x-intercepts. The x-coordinate of the midpoint is simply the average of the x-values:

x-coordinate of vertex = (0 + 0) / 2 = 0 / 2 = 0

Since the y-coordinate of the vertex is the same as the y-intercept, the vertex will have the coordinates (0, 0).

Therefore, the vertex of the quadratic function is (0, 0).
