Part A: The total area of the brick paver border is \(960\) square feet.

Part B: The total cost of the brick pavers needed for this project is $\(7,680\).

Part A: To find the total area of the brick paver border, we need to subtract the area of the pool from the area of the larger rectangle. The area of the pool is \(32\) feet multiplied by 12 feet, which is equal to \(384\)square feet.

The area of the larger rectangle is \(48\) feet multiplied by \(28\) feet, which is equal to \(1,344\) square feet. Therefore, the area of the brick paver border is \(1,344\) square feet minus \(384\) square feet, which equals \(960\) square feet.

Part B: If brick pavers cost $\(8\)per square foot, we can calculate the total cost by multiplying the cost per square foot by the total area of the brick paver border. The total area of the brick paver border is \(960\) square feet, and the cost per square foot is $\(8\).

Therefore, the total cost of the brick pavers needed for this project is $\(8\)multiplied by \(960\) square feet, which equals $\(7,680\).

Note: The calculations provided assume that the border consists of a single layer of brick pavers.

The correct statement regarding the angle measures is given as follows:

m < 1 + m < 4 > m < 3.

The given angle measure is as follows:

m < 3 = 119º.

Angles 3 and 4 form a linear pair, meaning that they are supplementary, that is, the sum of their measures is of 180º.

Hence the measure of angle 4 is given as follows:

m < 4 + m < 3 = 180º.

m < 4 = 180º - 119º

m < 4 = 61º.

Angles 1 and 4 are opposite by the same vertex, hence they are congruent, thus the measure of angle 1 is given as follows:

m < 1 = m < 4

m < 1 = 61º.

Hence:

m < 1 + m < 4 = 2 x 61

m < 1 + m < 4 = 122º

122º > 119º

m < 1 + m < 4 > m < 3.

The total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

From the figure, the area of triangles can be calculated using the:

Area = (1/2)height×base length

Area of three triangle = 1/2(4×6) + 1/2(6×4) + 1/2(4×6)

Area of three triangle = 1/2(24×3) = 36 square units

Area of the figure = area of three triangle + area of the rectangle

= 36 + 6×4

= 60 square units

Thus, the total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

Answer:

36 < (x - 2)² + (y + 3)² and 16 > (x - 4)² + y²

Step-by-step explanation:

This is because the shaded area is inside the first circle (centered at (4, 0) with a radius of 4) but outside the second circle (centered at (2, -3) with a radius of 6). The inequalities reflect these conditions by setting the inequality signs accordingly. The inequality with "<" for the first circle ensures that the shaded area is within the circle, and the inequality with ">" for the second circle ensures that the shaded area is outside the circle.

The required p(x > 4) when the probability of success and number of trials in the binomial process are given is calculated to be 0.01024.

It is given that the success is 40 percent.

So, the probability of success (p) is 0.40.

The number of trials (n) is 5.

Now, let us find out p(x > 4)

p(x > 4) = p(5)

⇒ ⁵C₅ (0.4)⁵ (1 - 0.4)⁰

⇒ 1 × (0.4)⁵ × 0.6

Step-by-step explanation:

Answer:

\( z =\frac{1418-1458}{\frac{354}{\sqrt{313}}}= -2.0\)

\( z =\frac{1498-1458}{\frac{354}{\sqrt{313}}}= 2.0\)

And we can find this probability with this difference and using the normal standard distribution or excel and we got:

\( P(-2<z<2) = P(z<2) -P(z<2)= 0.977-0.0228 = 0.9542\)

Step-by-step explanation:

For this case we know the following parameters:

\( \mu = 1458, \sigma = 354\)

We select a sample size of n = 313 and we want to find the following probability:

\( P( 1458- 40 <\bar X < 1458 + 40)= P(1418< \bar X < 1498)\)

And we can use the z score formula given by:

\( z =\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}\)

And using this formula we have:

\( z =\frac{1418-1458}{\frac{354}{\sqrt{313}}}= -2.0\)

\( z =\frac{1498-1458}{\frac{354}{\sqrt{313}}}= 2.0\)

And we can find this probability with this difference and using the normal standard distribution or excel and we got:

\( P(-2<z<2) = P(z<2) -P(z<2)= 0.977-0.0228 = 0.9542\)

The equation of the parabola is y = 2x²+2x+3 if the points (-1,3),(0.5,4.5) and (0,3) belong to it.

It is defined as the graph of a quadratic function that has something bowl-shaped.

Let's assume the equation of the parabola is:

\(\rm y = ax^2+bx+c\)

The points (-1,3), (0.5,4.5) and (0,3) belong to it.

Putting these points in the parabola equation, we get:

\(\rm 3 = a(-1)^2+b(-1)+c\\\\\rm a-b+c = 3 \ .....(1)\)

\(\rm 0.25a+0.5b+c = 4.5\) ....(2)

\(\rm c = 3\) ....(3)

The above shows a linear equation in three variables after solving, we get:

a = 2, b = 2, and z = 3

\(\rm y = 2x^2+2x+3\)

We can conclude that the hypotheses of the Existence and Uniqueness Theorem are satisfied in any rectangular region in the ty-plane that does not contain the curve t² + y² = -1.

The Existence and Uniqueness Theorem for first-order ordinary differential equations states that if a differential equation of the form y' = f(t, y) satisfies the following conditions in some rectangular region in the ty-plane:

1. f(t, y) is continuous in the region.

2. f(t, y) satisfies a Lipschitz condition in y in the region, i.e., there exists a constant L > 0 such that |f(t, y₁) - f(t, y₂)| ≤ L|y₁ - y₂| for all t and y₁, y₂ in the region.

then there exists a unique solution to the differential equation that passes through any point in the region.

In the case of the differential equation y' = (y cot(2t)) / (t² + y² + 1), we have:

f(t, y) = (y cot(2t)) / (t² + y² + 1)

This function is continuous everywhere except at the points where t² + y² + 1 = 0, which is the curve t² + y² = -1 in the ty-plane. Since this curve is not included in any rectangular region, we can say that f(t, y) is continuous in any rectangular region in the ty-plane.

To check if f(t, y) satisfies a Lipschitz condition in y, we can take the partial derivative of f with respect to y and check if it is bounded in any rectangular region. We have:

∂f/∂y = cot(2t) / (t² + y² + 1) - (2y² cot(2t)) / (t² + y² + 1)²

Taking the absolute value and simplifying, we get:

|∂f/∂y| = |cot(2t) / (t² + y² + 1) - (2y² cot(2t)) / (t² + y² + 1)²|

= |cot(2t) / (t² + y² + 1)| * |1 - (2y² / (t² + y² + 1)))|

Since 0 ≤ (2y² / (t² + y² + 1)) ≤ 1 for all t and y, we have:

1/2 ≤ |1 - (2y² / (t² + y² + 1)))| ≤ 1

Also, cot(2t) is bounded in any rectangular region that does not contain the points where cot(2t) is undefined (i.e., where t = (k + 1/2)π for some integer k). Therefore, we can find a constant L > 0 such that |∂f/∂y| ≤ L for all t and y in any rectangular region that does not contain the curve t² + y² = -1.

The graph representing the solution of the inequalities y < 3/4x + 3 and y ≤ -2x - 1 is option B.

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.

The first inequality is given as y < 3/4x + 3.

The second inequality is given as y ≤ -2x - 1.

To find the intersection point for the system of inequalities without graphing, we need to solve the two inequalities simultaneously by finding the values of x and y that satisfy both of them.

We can start by setting the two inequalities equal to each other -

y = 3/4x + 3 (from the first inequality)

y = -2x - 1 (from the second inequality)

Since both equations are equal to y, we can set them equal to each other -

3/4x + 3 = -2x - 1

We can simplify and solve for x -

3/4x + 2x = -1 - 3

11/4x = -4

x = -16/11

To find the value of y that corresponds to this value of x, we can substitute it into either equation.

Using the second equation, we have -

y = -2(-16/11) - 1

y = 29/11

So, the intersection point for the system of inequalities is (-16/11, 29/11).

The graph for inequality y ≤ -2x - 1 will be a straight line denoting (≤,≥) symbol.

The graph for inequality y < 3/4x + 3 will be a dotted line denoting (<,>) symbol.

Therefore, the graph that shows this intersection point and satisfies the condition is graph of option B.
