Therefore, Wildhorse needs to service at least 2 lawns per month to break even and cover its operating costs.

To determine the break-even point for Wildhorse in terms of the number of lawns serviced per month, we need to calculate the total cost and the contribution margin per lawn.

Total cost per lawn = Depreciation + Advertising + Insurance + Weed and feed materials + Direct labor + Fuel

= $1,400 + $150 + $2,475 + $20 + $12 + $3

= $4,060

Contribution margin per lawn = Revenue per lawn - Total cost per lawn

= $70 - $4,060

= -$3,990

The contribution margin is negative, indicating that the company incurs a loss of $3,990 per lawn serviced.

To determine the break-even point, we divide the fixed costs by the contribution margin per lawn:

Break-even point (in number of lawns) = Total fixed costs / Contribution margin per lawn

= $4,060 / (-$3,990)

≈ 1.019 lawns

Since we can't have a fraction of a lawn, the break-even point is rounded up to 2 lawns serviced per month.

Matrices are a powerful mathematical tool that can be used to solve equations, represent transformations, and analyze data in many different fields.

A matrix is a rectangular array of numbers. In mathematics, matrices are commonly used to solve systems of linear equations. The determinant is a scalar value that can be calculated from a square matrix. Matrices can be used in many applications, including engineering, physics, and computer science.To perform operations on matrices, it is important to understand matrix arithmetic. Addition and subtraction are straightforward: simply add or subtract the corresponding elements of each matrix. However, multiplication is more complex. To multiply two matrices, you must use the dot product of rows and columns. This requires that the number of columns in the first matrix match the number of rows in the second matrix. The product of two matrices will result in a new matrix that has the same number of rows as the first matrix and the same number of columns as the second matrix.A 2 × 2 matrix is a special case that is particularly useful in transformations of the plane. A 2 × 2 matrix can be used to represent a transformation that stretches, shrinks, rotates, or reflects a shape. The determinant of a 2 × 2 matrix can be used to find the area of the shape that is transformed. Specifically, the absolute value of the determinant represents the factor by which the area is scaled. If the determinant is negative, the transformation includes a reflection that flips the shape over.

Answer: x = -4 and x = 2.

To factor a quadratic equation in the form of x^2 + bx + c = 0, we need to find two numbers that when multiplied together, give us c, and when added or subtracted, give us b.

We need to find two numbers whose product is -8 and whose sum is 2. These numbers are 4 and -2, so we can write:

x^2 + 2x - 8 = (x + 4)(x - 2) = 0

Setting each factor to zero, we get:

x + 4 = 0 or x - 2 = 0

Solving for x in each equation, we get:

x = -4 or x = 2

So, the solutions to the equation x^2 + 2x - 8 = 0 are x = -4 and x = 2.

Greatest number that divides 300, 560 and 500 is 20 .

Given numbers : 300, 560 and 500

the number of different possible teams that can be formed is equal to nCr, or n!/(r!(n-r)!).

Assuming that the state narcotics bureau has more than 5 agents from which to choose, the number of different possible teams that can be formed is equal to the number of combinations of 5 agents out of the total number of agents the bureau has. This can be calculated using the formula nCr (n choose r), where n is the total number of agents and r is the number of agents in each team, which in this case is 5.

Therefore, the number of different possible teams that can be formed is equal to nCr, or n!/(r!(n-r)!).

Considering the definition of an inequality, the number of days Sebastian can afford to rent while staying within his budget is less than or equal to 6.

An inequality is the existing inequality between two algebraic expressions, connected through the signs:

An inequality contains one or more unknown values ​​called unknowns, in addition to certain known data.

Solving an inequality consists of finding all the values ​​of the unknown for which the inequality relation holds.

In this case, you know that:

Being "d" the number of days Sebastian can afford to rent while staying within his budget, the inequality that expresses the previous relationship is

40.50×d - 400×0.12 ≤ 210

Solving:

40.50×d - 48 ≤ 210

40.50×d ≤ 210 + 48

40.50×d ≤ 258

d ≤ 258÷ 40.50

No, at 0°F the ticket sales would be -631.25 and it is not reasonable (or possible) to have negative ticket sales in a linear regression model for predicting ticket sales.

In the statistics, the concept of regression analysis is useful for creating a predictive model that predicts the value of a target or dependent variable using all the controlling independent or explanatory variables. Depending on the number of independent variables, regression can be called simple regression or multiple regression. We have a linear regression model that predicts ticket sales for popular water parks.

The regression line equion in this model is written as -631.25 + 11.25 (current temperature in degree F). Comparing above equation with y = a + bx, here, the interaction in the equation above means that hourly ticket sales will be -631.25 when the current temperature (in degrees Fahrenheit) is 0. This does not make sense because hourly ticket sales can be at least 0 but never a negative number. So, it is not reasonable interpretation.

The probability of the soft drink machine filling a cup between 2121 and 3030 ounces with a normal distribution of the mean of 2727 ounces and a standard deviation of 33 ounces is 0.

It is given that the soft drink machine's output is normally distributed.

We know that for any normal distribution with X~(μ,σ)

f(z)= 1/σ√2π . e^(-(x - μ)²/2σ²),for all z ∈ R.

where  μ = The mean of the distribution

σ = the standard deviation of the distribution

Here

μ = 2727

σ = 33

We need to find

P(2121< x < 3030)

We know that the relation between a normal distribution and its Z-score is

P(a < X < b) = Φ((b- μ)/ σ)  -  Φ(a - μ/ σ)

here a = 2121  and  b = 3030

Therefore we get

P(2121< x < 3030) = Φ((3030- 2727)/ 33)  -  Φ(2121 - 2727/ 33)

= Φ((303)/ 33)  -  Φ(-606/ 33)

= Φ((303)/ 33)  -  Φ(-606/ 33)

= Φ((9.181818)  -  Φ(-18.363636)

Step-by-step explanation:

Put a negative next to 2^8 and you'll get your answer.

The equation that describes the simple harmonic motion of the particle is:

x = 7 * sin(2t + φ)

The equation that describes the simple harmonic motion of a particle moving uniformly around a circle can be represented as:

x = A * sin(ωt + φ)

In this equation:

x represents the displacement of the particle at time t.

A represents the amplitude of the motion.

ω represents the angular frequency or angular speed of the motion.

t represents time.

φ represents the phase constant.

In the given scenario, the particle is moving uniformly around a circle of radius 7 units, with an angular speed of 2 radians per second. In circular motion, the displacement can be represented by the arc length along the circumference of the circle.

Since the angular speed is 2 radians per second, the angular frequency (ω) is also 2 radians per second.

Since the particle is moving uniformly, the amplitude of the motion (A) is equal to the radius of the circle, which is 7 units.

The phase constant (φ) determines the initial position of the particle at t = 0.

Question 12: Find the slope from these two points: (-3,-3) and (-4,-8)

The formula for finding the slope from two points is attached to this answer.

So if we plug in our values that correspond to the formula we get the following:

First pair: -3 is our x1, -3 is our y1,

Second pair: -4 is our x2, -8 is our y2

-8--3/-4--3

-8+3/-4+3

-5/-1=5, Our slope is 5 for question 12

Question 18: Find the area of a circle with a diameter of 31.

Area=\(\pi r^2\)

\(5^{2} +b^{2} =8^{2}\)

\(25+b^{2} =64\)

Subtract 25

\(b^{2} =39\)

b would equal 6.44 something but the question said to round to the nearest whole number which would be 6.

Question 23: Find the volume of a cone

Radius: 10, height: 7

Formula to find the volume of a cone: 1/3 times 3.14 times r^2 times the height

1/3 times 3.14 times 700

1.046 (the 46 is repeating) repeating times 700

732.06 repeating, the 6 is repeating.

The question also asks us to round to the nearest whole number so the answer to question 23 would be 733

Question 26: Find the volume of a sphere

Radius is 6 and pi is 3.14

Formula: \(4\pi \frac{r^3}{3}\)

It is difficult to give a precise answer without more information, such as the thickness of the sauce and the desired coverage. However, if we assume that the sauce is being applied evenly and that a thin layer is desired, the amount of sauce needed to cover a 16" pizza would be approximately 50.24 in2. This is because the area of a circle with a diameter of 16" is approximately 50.24 in2. To calculate the area of a circle, you can use the formula A = πr^2, where A is the area, π is approximately 3.14, and r is the radius of the circle (which is half the diameter). In this case, the radius would be 8" and the area would be approximately 50.24 in2.

Answer:

f(9.5) = 558.02.

Step-by-step explanation:

Because it is an exponential function, it can be written: y = (a)(b)^x

Now substitute in the two known points:

72 = (a)(b)^7.5 and

2 = (a)(b)^4 : => since 2 = (a)(b)^2 divide the left side by 2 and the right by (a)(b)^2

72/2 =[(a)(b)^7.5]/[(a)(b)^4]: => the (a) cancels out and b becomes b^(7.5–4)

36 = b^3.5: => To isolate b take the 3.5 root of both sides

{3.5 root}(36) = {3.5 root}(b^3.5)

2.783927 = b

Now to solve for a

2 = (a)(b)^4 => 2 = (a)(2.783927)^4 => 2 = (a)(60.066375) divide both sides by 60.066375 0.0332965 = a

Equation: y = (0.0332965)(2.783927)^x

Now plug in 9.5 for x

(0.0332965)(2.783927)^9.5 = 558.0178525 = 558.02

The root of the equation sinx = 2x-3 is 0.8401 (approx).

Given equation is sinx = 2x-3

We need to solve this equation using false position method.

False position method is also known as the regula falsi method.

It is an iterative method used to solve nonlinear equations.

The method is based on the intermediate value theorem.

False position method is a modified version of the bisection method.

The following steps are followed to solve the given equation using the false position method:

1. We will take the end points of the interval a and b in such a way that f(a) and f(b) have opposite signs.

Here, f(x) = sinx - 2x + 3.

2. Calculate the value of c using the following formula: c = [(a*f(b)) - (b*f(a))] / (f(b) - f(a))

3. Evaluate the function at point c and find the sign of f(c).

4. If f(c) is positive, then the root lies between a and c. So, we replace b with c. If f(c) is negative, then the root lies between c and b. So, we replace a with c.

5. Repeat the steps 2 to 4 until we obtain the required accuracy.

Let's solve the given equation using the false position method.

We will take a = 0 and b = 1 because f(0) = 3 and f(1) = -0.1585 have opposite signs.

So, the root lies between 0 and 1.

The calculation is shown in the attached image below.

Melina needs 420 centimeters of ribbon.

We know that the volume of cylinder with radius of base r and height h is given by,

\(V=\pi r^2h\)

And the curved surface area of the same is,

\(C=2\pi rh\)

Given that, the height of the vase is 10 cm

Let the radius of the base be r cm.

So the volume is \(=10\pi r^2\)

Given that the volume is 1400 cubic centimeters. So,

\(10\pi r^2=1400\\\frac{22}{7}r^2=140\\r^2\approx44.54\\r\approx6.67\)

So the required ribbon \(=2\pi rh=2\times\frac{22}{7} \times6.67\times10\approx420\)
