Answer:

50%

Step-by-step explanation:

percent change = (new number - old number)/(old number) × 100%

Here, the new number is 2.

The old number is 4.

percent change = (2 - 4)/(4) × 100%

percent change = -2/4 × 100%

percent change = -50%

Since the percent change is negative, it's a percent decrease.

The percent decrease is 50%.

Real-life problem:

A farmer has a rhombus-shaped field with a side length of 50 meters and a height of 30 meters. He wants to build a fence around the field to keep his cows from wandering off. If he plans to use wire fencing that costs $4 per meter, how much will he spend on fencing?

Solution:

To find the perimeter of the field, we need to calculate the length of each side. Since a rhombus has four equal sides, we can use the Pythagorean theorem to find the length of each side:

a^2 + b^2 = c^2

where a and b are the side lengths, and c is the diagonal.

Since the height of the rhombus is 30 meters and the side length is 50 meters, we can use these values to find the diagonal:

c^2 = 30^2 + 50^2

c^2 = 900 + 2500

c^2 = 3400

c = sqrt(3400)

c = 58.31 meters

Therefore, the perimeter of the field is 4 x 50 = 200 meters.

The farmer plans to use wire fencing that costs $4 per meter. So, the total cost of fencing will be:

Cost = perimeter x cost per meter

Cost = 200 x 4

Cost = $800

Answer:

The farmer will spend $800 on fencing the rhombus-shaped field.

Answer:

AA similarity (Postulate).

Step-by-step explanation:

The AA Similarity Postulate states that two triangles are similar if all their corresponding angles are congruent, and their corresponding sides are proportional.

In this case:

∡ACE ≅ ∡DBE (Given)

∡BED ≅ ∡AEC (Vertical Angles Theorem)

For Proportionality, you will have to get more information on the measurements of the sides. As side measurements are not given, you cannot use any similarities based on sides to prove the similarities of the triangles.

The equation of the tangent line to f(x)=ln(x) at x=2 is given by y = 1/2x - ln(2).

To find the formula for the tangent line to f(x)=ln(x) at x=2, we first need to take the derivative of the function:

f'(x) = 1/x

At x=2, the derivative is:

f'(2) = 1/2

The equation of the tangent line at x=2 is given by:

y - f(2) = f'(2)(x - 2)

Substituting the values of f(2) and f'(2) gives:

y - ln(2) = 1/2(x - 2)

Simplifying this equation gives us the equation of the tangent line:

y = 1/2x - ln(2) + ln(2)

Therefore, the equation of the tangent line to f(x)=ln(x) at x=2 is given by y = 1/2x - ln(2).

What is midpoint ?

The point on a line that is at an equal distance from either end.

Here, the coordinates of \(A(1,-1),P(3,7),Q(\frac{-1}{2},\frac{7}{2})\)

The general formula of the midpoint is

\((x_m,y_m)=(\frac{x_1+x_2}{2},\frac{y_1+t_2}{2})\)

The equation of \(AP\) is

\(AP=(\frac{1+3}{2},\frac{7-1}{2})\\AP=(\frac{4}{2},\frac{6}{2})\\AP=(2,3)\\\)

When more than 25 shirts are ordered, the price is $15 per shirt, plus $15 shipping and handling.  If $720 was spent on shirts,  the student council ordered 47 shirts.

Let x be the number of shirts ordered. We can set up an equation based on the given information:

If x ≤ 25, then the cost of the shirts is 20x + 20.

If x > 25, then the cost of the shirts is 15x + 15.

We know that the total cost of the shirts is $720. So, we can write:

20x + 20 if x ≤ 25

15x + 15 if x > 25

Setting these equal to each other, we get:

20x + 20 = 15x + 15

5x = 5

x = 1

This doesn't make sense, because the number of shirts ordered must be greater than 1. Therefore, we know that the student council ordered more than 25 shirts.

Using the equation 15x + 15 = 720, we can solve for x:

15x + 15 = 720

15x = 705

x = 47

To check, we can calculate the cost of the shirts:

If 47 shirts are ordered, then the cost is 15(47) + 15 = $720.

As a result, the parabola's equation for B  is y = -1/2(x - 1)² + 4.

A parabola with vertex (h,k) has the basic equation y = a(x-h)² + k². In this instance, h=0 and k=-5 are equal because the vertex is at $(0,-5)$. Moreover, the parabola has a point at (-1 . 2). When we substitute these numbers in the general parabola equation, we obtain:

2 = a(-1-0)² -5

7 = a

The parabola's equation is therefore y = 7x2 - 5$1.

A cone and a plane perpendicular to its side cross to create a symmetrical open plane curve known as a parabola1. It is a U-shaped curve whose vertex and axis of symmetry characterise it. The line dividing the parabola into its two mirror counterparts is known as the axis of symmetry. The parabola's vertex is where the axis of symmetry intersects it.

A parabola's vertex is represented by the equation y = a(x - h)²+ k, where (h,k) represents the vertex. We may utilise the vertex version of the equation and substitute the values of h, k, and the x and y coordinates of the point to determine the equation of a parabola that passes through a particular point and has a certain vertex.

B.  Here, the vertex is (1, 4), and the point (5,-4). In the vertex form equation, we may therefore substitute h=1, k=4, x=5, and y=-4 to obtain:

Answer: "Point A is a solution because it is in the shaded area

Step-by-step explanation:

When we have an inequality like the one shown in the graph, the shaded area represents the possible solutions to the inequality.

If we have a dashed line, then the points in the line are not solutions (this is the case of the symbols > and < )

If the line is solid, then the points of the line are solutions (this is the case of the symbols ≤ and ≥)

In the graph we can see that point A is inside the shaded area, then point A is a solution.

Then the correct option is:

"Point A is a solution because it is in the shaded area"

Therefore, the solution to Equation (5) is:

\(V_y(x, y, t) = ± √(m^2 - 5m/q^2) exp(±imV_B t + i sin(y))\)

To solve the given partial differential equations, we will start by solving Equation (4) and then use the solution to solve Equation (5). Let's go through the steps:

Step 1: Solve Equation (4):

We are given the equation:

∂^2V_x/∂t^2 = - (mV_B)^2V_x

To solve this equation, we assume a solution of the form V_x(x, y, t) = V_1 exp(±iω_c t + i sin(y))

Substituting this solution into Equation (4), we get:

\((-ω_c^2) V_1 exp(±iω_c t + i sin(y)) = - (mV_B)^2 V_1 exp(±iω_c t + i sin(y))\)

Dividing both sides by V_1 exp(±iω_c t + i sin(y)), we obtain:

\(-ω_c^2 = - (mV_B)^2\)

Simplifying, we get:

ω_c = ± mV_B

Therefore, the solution to Equation (4) is:

V_x(x, y, t) = V_1 exp(±imV_B t + i sin(y))

Step 2: Solve Equation (5):

We are given the equation:

\(∂^2V_y/∂t^2 = - (m/qz)^2 V_y - 5 V(x, y)\)

Using the solution from Step 1, we have:

V(x, y) = V_1 exp(±imV_B t + i sin(y))

Substituting this into Equation (5), we get:

\((-ω_c^2) V_1 exp(±imV_B t + i sin(y)) = - (m/qz)^2 V_y - 5 V_1 exp(±imV_B t + i sin(y))\)

Dividing both sides by V_1 exp(±imV_B t + i sin(y)), we obtain:

\(-ω_c^2 = - (m/qz)^2 - 5\)

Substituting ω_c = ± mV_B, we have:

\(-(mV_B)^2 = - (m/qz)^2 - 5\)

Simplifying, we get:

\((qz)^2 = m^2 - 5m/q^2\)

Taking the square root, we have:

\(qz = ± √(m^2 - 5m/q^2)\)

Therefore, the solution to Equation (5) is:

\(V_y(x, y, t) = ± √(m^2 - 5m/q^2) exp(±imV_B t + i sin(y))\)
