Answer:

A: tom has 15 more roses than ana does.

B: 11:4

Step-by-step explanation:

A: there is a 3:1 and 5:2 ratio of roses to tulips. that means that in tom's, there are 3 roses for every tulip and 5 roses for every 2 tulips in ana's.

we know that they each have 30 tulips so now for Tom.

3:1 so to find roses, we need to multiply the value of tulips to 3.

3×30=90 so we know he has a total of 90 roses.

for ana: she also has 30 tulips. BUT now her ratio is 5:2. so for every 2 tulips she has 5 roses. we need to divide the value of tulips by 2 so 30/2=15 and multiply it by 5, 15*5=75

THAT IS NOT THE ANSWER!! to find the rest of the answer, we have to subtract tom's amount by ana's amount: 90-75=15

B: to find this answer, we have to add all of the roses together and all of the tulips together. roses: 90+75=165. tulips: 30+30=60.

the ratio we get is 165:60. and now we need to simplify it.

Answer:

34,400 = m

Step-by-step explanation:

25,000 = 0.5m + 7,800

-7,800                -7,800          subtract 7,800 from both sides

17,200 = 0.5m

--------     ---------

0.5           0.5                  divide both sides by 0.5

And you should be left with 34,400 = m

To find a positive number such that the sum of and is as small as possible, we need to use optimization. This problem requires optimization over a closed interval. The given problem is as follows, Let x be a positive number. Find a positive number such that the sum of and is as small as possible.

To find a positive number such that the sum of and is as small as possible, we need to use optimization. This problem requires optimization over a closed interval. The given problem is as follows, Let x be a positive number. Find a positive number such that the sum of and is as small as possible. So, we need to minimize the sum of and . Now, let's use calculus to find the minimum value of the sum.To find the minimum value, we have to find the derivative of the sum of and , i.e. f(x) with respect to x, which is given by f '(x) as shown below:

f '(x) = 1/x^2 - 1/(1-x)^2

We can see that this function is defined on the closed interval [0, 1]. The reason why we are using the closed interval is that x is a positive number, and both endpoints are included to ensure that we cover all positive numbers. Therefore, the problem requires optimization over a closed interval. This means that the minimum value exists and is achieved either at one of the endpoints of the interval or at a critical point in the interior of the interval.

Ndidi rides y km at 10 km/hr, then walks 0.5y km at 3 km/hr. She is away from. home less than 4hours.Range of the values of Y is =24/7

Let's call the total time spent riding and walking t hours. We know that t is less than 4 hours, so:

t = time spent riding + time spent walking < 4 hours

The time spent riding is given by y / 10 km/hr and the time spent walking is given by 0.5y / 3 km/hr. So, we can write the inequality as:

t = y / 10 + 0.5y / 3 < 4

Expanding and simplifying the expression on the left side gives:

7/6y < 4 * 6/7

Multiplying both sides by 6/7 gives:

y < 4 * 6/7 * 6/7 = 24/7

So, the range of values of y is 0 < y < 24/7 km. This means that Ndidi rode less than 24/7 km, but more than 0 km.

A gradient vector field represents the direction and magnitude of the gradient of a function at each point in the plane. The function f(x, y) = 2x^2 + 2y^2 corresponds to the gradient vector field plot labeled with the equation "f(x, y) = 2x^2 + 2y^2."

A gradient vector field represents the direction and magnitude of the gradient of a function at each point in the plane. The gradient vector field can be visualized by plotting vectors at different points, with the vectors pointing in the direction of the steepest ascent of the function.

In this case, the function f(x, y) = 2x^2 + 2y^2 represents a quadratic function with the coefficients 2 for both x^2 and y^2 terms. The gradient vector field plot that corresponds to this function would show vectors pointing away from the origin (0, 0) in all directions, indicating the direction of steepest ascent.

By matching the function f(x, y) = 2x^2 + 2y^2 with the gradient vector field plot labeled with the equation "f(x, y) = 2x^2 + 2y^2," we can visually observe the direction and magnitude of the gradient vectors associated with the function at each point in the plane.

a. the costs of non-compliance, enforcement, prevention and evaluation are -75 d/p, -$7500, $17500 and $5000 respectively

b. The percentage of effort devoted to each component is:

a) To calculate the costs of non-compliance, enforcement, prevention, and evaluation, we need to determine the deviations in effort for each component and multiply them by the corresponding cost per person-day.

Non-compliance cost:

Non-compliance cost = Actual effort - Predicted effort

To calculate the actual effort, we need to sum up the effort for each component mentioned:

Actual effort = Plan development + Software development + Reviews + Tests + Training + Methodology

Actual effort = 25 + 75 + 20 + 30 + 20 + 5 = 175 d/p

Non-compliance cost = Actual effort - Predicted effort = 175 - 250 = -75 d/p

Enforcement cost:

Enforcement cost = Non-compliance cost * Cost per person-day

Assuming a cost of $100 per person-day, we can calculate the enforcement cost:

Enforcement cost = -75 * $100 = -$7500 (negative value indicates a cost reduction due to underestimation)

Prevention cost:

Prevention cost = Predicted effort * Cost per person-day

Assuming a cost of $100 per person-day, we can calculate the prevention cost for each component:

Plan development prevention cost = 25 * $100 = $2500

Software development prevention cost = 75 * $100 = $7500

Reviews prevention cost = 20 * $100 = $2000

Tests prevention cost = 30 * $100 = $3000

Training prevention cost = 20 * $100 = $2000

Methodology prevention cost = 5 * $100 = $500

Total prevention cost = Sum of prevention costs = $2500 + $7500 + $2000 + $3000 + $2000 + $500 = $17500

Evaluation cost:

Evaluation cost = Total project cost - Prevention cost - Enforcement cost

Evaluation cost = $25000 - $17500 - (-$7500) = $5000

b) To calculate the percentage of effort devoted to each component out of the total cost, we can use the following formula:

Percentage of effort = (Effort for a component / Total project cost) * 100

Percentage of effort for each component:

Plan development = (25 / 250) * 100 = 10%

Software development = (75 / 250) * 100 = 30%

Reviews = (20 / 250) * 100 = 8%

Tests = (30 / 250) * 100 = 12%

Training = (20 / 250) * 100 = 8%

Methodology = (5 / 250) * 100 = 2%

(c) you can see from the graph, the purple line hits the parabola twice which is y=6   or k=6

(d)  Solving simultaneously can mean to set equal

6x - x² = k                        >subtract k from both sides

6x - x² - k = 0                  >put in standard form

- x² + 6x - k = 0               >divide both sides by a -1

x² - 6x + k = 0

(e) The new equation is the same as the original equation just flipped (see image)

(f)  The discriminant is the part of the quadratic equation that is under the root. (not sure if they wanted the discriminant of new equation or orginal.  I chose new)

discriminant formula = b² - 4ac

equation:   x² - 6x + 6 = 0            a = 1      b=-6    c = 6

discriminant = b² - 4ac

discriminant= (-6)² - 4(1)(6)

discriminant = 36-24

discriminant = 12

Because the discriminant is positive, if you put it back in to the quadratic equation, you will get 2 real solutions.

It will take 120 minutes for smaller hose to fill the complete swimming pool on its own.

Let us represent the complete swimming pool as 1. Now, total time required to fill the swimming pool is 40 hours. So, amount of swimming pool filled in 1 minute = 1/40

Similarly, amount fo swimming pool filled by larger hose in 1 minute = 1/60

Now for the smaller hose, the amount of swimming pool filled in 1 minute = 1/40 - 1/60

The amount of swimming pool filled in 1 minute = (60 - 40)/2400

The amount of swimming pool filled in 1 minute = 20/2400

The amount of swimming pool filled in 1 minute = 1/120

Total time taken to fill swimming pool = 1 ÷ (1/120)

Total time taken to fill swimming pool = 120 minutes

Thus, 120 minutes are required.

The number of significant digits in a measurement is determined by following a specific rule. According to the rule, all non-zero digits in a measurement are considered significant. For example, in the measurement 25.4 cm, there are three significant digits (2, 5, and 4) because they are non-zero.

In addition to non-zero digits, there are two more rules to consider. The first rule states that all zeros between non-zero digits are also significant. For instance, in the measurement 1003 g, there are four significant digits (1, 0, 0, and 3) because the zero between the non-zero digits is significant.

The second rule states that trailing zeros at the end of a number are significant only if they are after the decimal point. For example, in the measurement 2.000 s, there are four significant digits (2, 0, 0, and 0) because the trailing zeros after the decimal point are significant. However, in the measurement 2000 m, there are only one significant digit (2) because the trailing zeros are not after the decimal point.

In summary, the number of significant digits in a measurement is determined by considering all non-zero digits, zeros between non-zero digits, and trailing zeros after the decimal point. These rules help in properly representing the precision and accuracy of a measurement.

That is the answer

For the first polynomial, we cannot determine if any roots are in the Right Half Plane (RHP) without knowing the values of coefficients.

For the second polynomial, we also cannot determine the number of poles in the RHP, LHP, or on the jω axis without knowing the values of coefficients.

For the third polynomial, we also cannot determine if any roots are in the RHP without knowing the values of coefficients.

What is a Routh Table?

A Routh table, also known as a Routh-Hurwitz table, is a tabular method used in control systems engineering to analyze the stability of a linear system. It is named after Edward J. Routh and Adolf Hurwitz, who independently developed the method.

p(s) = s⁶ + 4s⁵ + 3s⁴ + 2s³ + s² + 4s + 4

To determine if any roots are in the Right Half Plane (RHP), we check the signs of the elements in the first column of the Routh array. If any sign changes occur, it indicates roots in the RHP.

In this case, the signs are as follows:

Row 1: 1 (positive)

Row 2: 4 (positive)

Row 3: (2b-12)/4 (unknown)

Row 4: (4e-2c)/4 (unknown)

Row 5: (2c-4d)/4 (unknown)

Row 6: 4d (unknown)

Row 7: f (unknown)

Since we have a row with all unknown signs (Row 3 onwards), we cannot determine if any roots are in the RHP. To make further conclusions, we would need to know the values of the coefficients a, b, c, d, e, and f.

Moving on to the second polynomial:

p(s) = s⁵ + 5s⁴ + 11s³+ 23s² + 28s + 12

To determine the number of poles on the Right Half Plane (RHP), Left Half Plane (LHP), and jω axis, we count the number of sign changes in the first column of the Routh array.

In this case, the signs are as follows:

Row 1: 1 (positive)

Row 2: 5 (positive)

Row 3: (23a-5*12)/23 (unknown)

Row 4: 12b

To determine the sign of the element (23a-5*12)/23 in Row 3, we need to consider two cases:

Case 1: If (23a-512)/23 > 0, then the sign remains positive.

Case 2: If (23a-512)/23 < 0, then the sign changes.

Similarly, for Row 4, if 12b > 0, the sign remains positive. If 12b < 0, the sign changes.

Without knowing the values of coefficients 'a' and 'b', we cannot determine the exact number of sign changes. Therefore, we cannot determine the number of roots in the Right Half Plane (RHP), Left Half Plane (LHP), or on the jω axis for this polynomial.

Moving on to the third polynomial:

p(s) = s⁵ + 3s⁴ + 2s³ + 6s² + 6s + 9

To determine if any roots are in the Right Half Plane (RHP), we check the signs of the elements in the first column of the Routh array.

Row 1: 1 (positive)

Row 2: 3 (positive)

Row 3: (6a-3*9)/6 (unknown)

Row 4: 9b (unknown)

Row 5: c (unknown)

Row 6: d (unknown)

Since we have a row with all unknown signs (Row 3 onwards), we cannot determine if any roots are in the RHP without knowing the values of coefficients 'a', 'b', 'c', and 'd'.

Hence,

For the first polynomial, we cannot determine if any roots are in the Right Half Plane (RHP) without knowing the values of coefficients.

For the second polynomial, we also cannot determine the number of poles in the RHP, LHP, or on the jω axis without knowing the values of coefficients.

An equation that represents the value of the stamp is V(t) = V₀ * (1 + r)ˣ

The value of the stamp after 10 years would be approximately $56.34.

First, let's denote the initial value of the stamp as V₀ and the number of years as t. In this case, V₀ is equal to $50. The annual increase rate is given as 1.2%, which can be expressed as 0.012 in decimal form.

Now, we can start building the equation. Since the value of the stamp increases every year, we need to add the rate of increase to the previous year's value. Mathematically, this can be represented as:

V(t) = V₀ + (V₀ * r) + (V₀ * r) + ... + (V₀ * r)

Here, V(t) represents the value of the stamp after t years, and r represents the rate of increase (0.012 in decimal form).

Since the rate of increase remains constant at 1.2% each year, we can simplify the equation using exponential notation:

V(t) = V₀ * (1 + r)ˣ

Now we have an equation that represents the value of the stamp after t years, where V₀ is the initial value ($50), r is the rate of increase (0.012), and x is the number of years.

To find the value of the stamp after 10 years, we substitute t = 10 into the equation:

V(10) = $50 * (1 + 0.012)¹⁰

Calculating this equation will give us the value of the stamp after 10 years. Let's perform the calculation:

V(10) = $50 * (1.012)¹⁰

V(10) ≈ $50 * 1.1268250301

V(10) ≈ $56.34

The algebraic representation that shows a dilation that is an enlargement is (5/2 x,5/2 y). (Option D)

A dilation is a type of transformation that changes the size of the shape or object.  It refers to a process of changing an object’s size by decreasing or increasing its dimensions by a scaling factor. A dilation produces an image that has the same shape as the original image but is a different size.

A dilation that results in a larger image is called an enlargement while a dilation that generates a smaller image is called a reduction. A dilation is described using the scale factor and the center of the dilation (which is a fixed point in the plane).

For a scale factor > 1, the image is an enlargement; for a scale factor < 1 and  > 0, the image is a reduction; and for a scale factor = 1, the figure and the image are congruent. Hence, for a point (x,y), algebraic representation that shows a dilation that is an enlargement is (5/2 x,5/2 y) as the scale factor is greater than 1. For the remaining options, the scale factor is between 0 and 1, hence they are reduction.
