How many solutions does this equation have?

7h - 7h = 0

Answer:

175 tickets

Step-by-step explanation:

The total cost is 875

y = mx

The y is the total cost.  The m is the cost of a ticket and x is the number of tickets that need to be sold

875 = 5x  Divide both sides by 5

175 = x

Answer:7  tickets

because 625+250 is 875 ..875/25=35

each ticket is $5 and 35/5 is 7

Using Euler's Method with a step size of h = 0.1, the approximate values of the solution at t = 0.1, 0.2, 0.3, 0.4, and 0.5 are:

t = 0.1: y ≈ 1.1

t = 0.2: y ≈ 1.22

t = 0.3: y ≈ 1.34

t = 0.4: y ≈ 1.47

t = 0.5: y ≈ 1.61

To use Euler's Method, we start with an initial condition. In this case, the given initial condition is y(0) = 1. We can then iteratively calculate the approximate values of the solution at each desired time point using the formula:

Yn = Yn-1 + h * F(Xn-1, Yn-1)

Here, h represents the step size (0.1 in this case), Xn-1 is the previous time point (t = Xn-1), Yn-1 is the solution value at the previous time point, and F(Xn-1, Yn-1) represents the derivative of the solution function.

For the given differential equation +2y = 2 - ey, we can rearrange it to the form y' = (2 - ey) / 2. The derivative function F(Xn-1, Yn-1) is then (2 - eYn-1) / 2.

Using the initial condition y(0) = 1, we can proceed with the calculations:

t = 0.1:

Y1 = Y0 + h * F(X0, Y0)

= 1 + 0.1 * [(2 - e^1) / 2]

≈ 1 + 0.1 * (2 - 0.368) / 2

≈ 1 + 0.1 * 1.316 / 2

≈ 1 + 0.1316

≈ 1.1

Similarly, we can calculate the approximate values of the solution at t = 0.2, 0.3, 0.4, and 0.5 using the same formula and previous results.

Using Euler's Method with a step size of h = 0.1, we found the approximate values of the solution at t = 0.1, 0.2, 0.3, 0.4, and 0.5 to be 1.1, 1.22, 1.34, 1.47, and 1.61, respectively.

The bottom of a 25 feet ladder is propped up against a wall, which is 7 feet away. When the ladder is 15 feet above the ground, 23.3 feet per second is the top of the ladder falling down the wall.

Given that,

The bottom of a 25 feet ladder is propped up against a wall, which is 7 feet away. A feet per second of the ladder's bottom begins to slide away from the wall.

We have to find when the ladder is 15 feet above the ground, how many feet per second is the top of the ladder falling down the wall.

Let us take x = height where the ladder hits the building

7 squared + x squared=25 squared

49+x squared=625

x squared=576

x=24 feet

Now,

If it slips 15 feet that 24-15=9 feet

Let x = distance from wall:

x² + 9² = 25²

x² + 81= 625

x² = 544

x = 23.3 feet

Therefore, when the ladder is 15 feet above the ground, 23.3 feet per second is the top of the ladder falling down the wall.

Answer:

≈ 83.9 cm²

Step-by-step explanation:

Given:

Then:

Area of  the triangle is found by using Herons formula:

where s = P/2 = 44/2 = 22 cm

Answer:

\(\huge \boxed{\mathrm{83.9 \ cm^2}}\)

Step-by-step explanation:

Two sides of the triangle are given.

The perimeter is given.

We need to solve for the third side.

\(P=a+b+c\)

\(P= \sf perimeter\)

\(a,b,c= \sf side \ lengths\)

\(44=18+12+c\)

\(c=14\)

The measure of the third side is 14 cm.

When three sides of the triangle are given, we can solve for the area using Heron’s formula.

\(A=\sqrt{s(s-a)(s-b)(s-c)}\)

\(s=\sf semi \ perimeter\)

\(\displaystyle s=\frac{P}{2} =\frac{44}{2} =22\)

Plugging in the values and evaluating.

\(A=\sqrt{22(22-18)(22-12)(22-14)}\)

\(A = 83.904708...\)

The area of the triangle is approximately 83.9 cm².

The value of the expression after evaluating it according to the values of c and d is 42.

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Since, no expression is given, let us assume that the expression is

c + d / 4

Now we have to evaluate the value of the expression according to the values of c and d,

For that, we will simply put the given values in the expression and solved it accordingly,

Put c = 36 and d = 24 in the expression we assumed,

c + d / 4 = 36 + 24/4

= 36 + 6 = 42

Hence, the value of the expression after evaluating it according to the values of c and d is 42.

Answer:D

(Sorry if I’m wrong)

The optimal solution using the two-phase simplex method for the given linear programming problem, we first need to convert it into standard form by introducing slack and surplus variables.

The problem can be rewritten as follows: Minimize Z = 2x1 + 3x2
subject to: 2x1 + 4x2 + s1 = 4
-x1 - 3x2 - s2 = -36
x1 + x2 = 10
x1, x2, s1, s2 ≥ 0

In the first phase of the simplex method, we introduce artificial variables and solve the problem to obtain an initial feasible solution. The initial tableau is constructed with the objective row as [0, 0, -M, -M, 0] and the constraint rows corresponding to the coefficients of the variables and artificial variables. Here, M represents a large positive number.

Next, we perform the simplex iterations to improve the solution. At each iteration, we pivot to select the entering and leaving variables until the optimal solution is reached. The iterations involve calculating the ratios of the right-hand side to the pivot column elements and selecting the minimum ratio as the pivot row.

In the second phase, we remove the artificial variables and proceed with the simplex iterations using the revised tableau. The iterations continue until the optimal solution is obtained, and the objective function value is minimized.

Unfortunately, I cannot generate the detailed steps and iterations of the two-phase simplex method in this text-based format. It requires a series of calculations and tabular representation. However, by following the steps of the two-phase simplex method, including initializing the tableau, performing simplex iterations, and removing the artificial variables in the second phase, you can find the optimal solution for the given problem.

Answer:

  walk area = 125.6 m²

Step-by-step explanation:

You are asked for the area of a sidewalk of given width that is around a circle of given radius. The pattern you're asked to fill in would have you compute the area of the inner circle, and of the outer circle, then find the difference between the areas.

__

The formula for the area of a circle is ...

  A = πr²

The radius is shown as 11 m, so its area is ...

  A = π(11 m)² = 121π m² = 379.94 m²

The radius is shown as 9 m, so its area is ...

  A = π(9 m)² = 81π m² = 254.34 m²

The difference between the two areas is ...

  walk area = big circle area - small circle area

  walk area = 379.94 m² -254.34 m² = 125.6 m²

_____

Additional comment

The area can also be computed by multiplying the centerline length of the sidewalk by its width. The center of the walk is (9+11)/2 = 10 m from the centers of the circles, so the circumference (centerline length) is

  C = 2πr = 2(3.14)(10 m) = 62.8 m

The width of the sidewalk is 11 -9 = 2 meters, so its area is ...

  (2 m)(62.8 m) = 125.6 m² . . . . sidewalk area

The equivalent equation of x^2 + 6x = 16 are (x + 3)^2 = 25 and x^2 + 6x + 9 = 25

From the question, we have the following parameters that can be used in our computation:

x2+6x=16

Express properly

So, we have the following representation

x^2 + 6x = 16

Add 9 to both sides of the equation

x^2 + 6x + 9 = 25 --- this represents option (c)

Expand

x^2 + 3x + 3x + 9 = 25

When the expression is factorized, we have

(x + 3)^2 = 25

the total parcel size is 88 acres.

Let's denote the total parcel size as X acres.

According to the given information, 1/4 of the land is allocated to shopping, which amounts to 22 acres. Therefore, we can set up the following equation:

(1/4) * X = 22

To find the value of X, we need to solve this equation for X.

Multiplying both sides of the equation by 4, we get:

X = 22 * 4

X = 88

Therefore, the total parcel size is 88 acres.

what is equation?

In mathematics, an equation is a statement that asserts the equality of two expressions. It consists of two sides, known as the left-hand side (LHS) and the right-hand side (RHS), connected by an equals sign (=).

The general form of an equation is:

LHS = RHS

The LHS and RHS can contain variables, constants, mathematical operations (such as addition, subtraction, multiplication, and division), functions, and other mathematical expressions.

The goal when working with equations is to find the values of the variables that satisfy the equation, making both sides equal. This process is often referred to as solving the equation.

For example, the equation "2x + 5 = 13" states that the expression "2x + 5" is equal to 13. To find the value of x that satisfies this equation, we can manipulate the equation to isolate the variable:

2x + 5 - 5 = 13 - 5  (subtract 5 from both sides)

2x = 8

2x/2 = 8/2  (divide both sides by 2)

x = 4

In this case, the value of x that satisfies the equation is 4.
