Building rent: fixed cost, Toys: variable cost, Compensation of office manager: mixed cost, Afternoon snacks: variable cost, Lawn service cost at $200 a month: fixed cost, H's salary: fixed cost, Wages of after school employees: variable cost, Drawing paper for students' at work: variable cost, Straight-line depreciation on furniture and playground equipment: fixed cost, Fee paid to security company for monthly service: fixed cost.

Costs can be classified as fixed, variable, or mixed. Variable costs are those whose total dollar value vary according to the level of activity. A cost is considered constant if its overall sum does not change as the activity varies. Both fixed and variable costs have characteristics known as mixed or semi-variable costs.

Classify the given cost as fixed, variable or mixed costs:

1) Because building rent must be paid regardless of activity, it is a fixed expense.

2) The quantity of toys to be purchased is influenced by the number of children in H creche; as a result, this expense is variable.

It is a mixed cost because the office manager receives both a fixed salary and a variable incentive dependent on the number of children enrolled.

4) The cost of snacks is vary because it depends on how many kids are enrolled.

5) The contract is a pre-determined arrangement that is carried out regardless of the number of kids enrolled.

6) Because H must be given the consideration regardless of how many kids are registered in the creche, it is a fixed expense.

7) Since the number of children enrolled in creche would determine the amount of after-school personnel recruited, it is a variable expense.

8) Drawing paper purchases are variable costs because they depend on the number of registered youngsters.

9) Asset depreciation is periodically assessed, and it would be assessed even if there were no children enrolled.

10) The cost of the security service is fixed because it must be paid on a regular basis and is one of the expenses associated with operating the nursery.

To find the radius of convergence of the series

n=1

we use the ratio test:

lim   |[tex]4(-1)^{(n+1)}*(n+1)*x^{(n+1)}[/tex]|    |[tex]4(x)(-1)^n*n*x^n[/tex]|

n->∞  |[tex]4(-1)^n*n*x^n[/tex]|                  |[tex]4(-1)^n*n*x^n[/tex]|

= lim   |x|/n

n->∞

The limit of |x|/n approaches 0 as n approaches infinity, as long as |x| < 1. Therefore, the series converges absolutely for |x| < 1.

On the other hand, if |x| > 1, then the limit of the absolute value of the series terms does not approach zero, and therefore the series diverges.

If |x| = 1, then the series may or may not converge, depending on the value of x. In fact, when x = 1, the series becomes the alternating harmonic series, which converges. When x = -1, the series becomes 4 - 4 + 4 - 4 + ..., which oscillates and does not converge. Therefore, the interval of convergence is (-1,1].

Since the radius of convergence is the same as the distance from the center of the series (which is 0) to the nearest point where the series diverges or fails to converge, we have r = 1.

The equation for y (exponential function) is y = -7e⁰.⁵ˣ

An exponential function is a mathematical function with the formula f(x) = ax, where "a" is a positive constant and "x" is any real number. The exponential function's base is the constant "a." Depending on whether the base is larger than or less than 1, the exponential function graph is a curve that rapidly rises or falls. In many branches of mathematics and science, the exponential function is employed to simulate growth and decay processes. Exponential functions can be used to simulate a variety of phenomena, including population expansion, radioactive decay, and compound interest.

The following is the equation for y:

y = -7e⁰·⁵ˣ

Given this, dy/dx = (1/2)y

X=0 causes Y=-7.

We can thus write:

dy/dx = (1/2)y

dy/y = (1/2)dx

By combining both sides, we obtain:

ln|y| = (1/2)x + C

where C is the integration constant.

X=0 causes Y=-7.

So,

ln|-7| = C

C = ln(7)

Therefore,

(1/2)x + ln(7) = ln|y|

|y| = e⁰·⁵ˣ+ ln(7)

y = -7e⁰·⁵ˣ

To determine whether the series [infinity] k = 1 k2 k2 − 4k 7 is convergent or divergent, we can use the limit comparison test.

First, we note that k2 − 4k = k(k − 4), so the denominator of the terms in the series can be factored as k2(k − 4).

Next, we compare the series to the p-series ∑1/k2, which we know is convergent.

We take the limit as k approaches infinity of (k2/k2(k − 4)) = 1/(k − 4). This limit approaches 0 as k approaches infinity.

Therefore, by the limit comparison test, the series is convergent.

To find its sum, we can use the partial fraction decomposition:

1/(k2(k − 4)) = A/k + B/k2 + C/(k − 4)

Multiplying both sides by k2(k − 4), we get:

1 = A(k − 4) + Bk + Ck2

Plugging in k = 0 gives:

1 = -4A

So A = -1/4.

Plugging in k = 1 gives:

1 = -3A + B + C

So B + C = 13/12.

Plugging in k = 2 gives:

1/4 = -2A + B + 4C

So -8A + 4B + 16C = 1.

Solving this system of equations gives:

A = -1/4, B = 5/12, C = 1/3

Therefore, the sum of the series is:

∑ k = 1 to infinity 1/(k2(k − 4)) = ∑ k = 1 to infinity (-1/4k + 5/12k2 + 1/3(k − 4))

= (-1/4)∑ k = 1 to infinity 1/k + (5/12)∑ k = 1 to infinity 1/k2 + (1/3)∑ k = 1 to infinity 1/(k − 4)

= (-1/4)∞∑ k = 1 1/k + (5/12)π2/6 + (1/3)∞∑ k = 5 1/k

To find the selling price after applying a discount of 12% to goods bought for $1200, we can follow these steps:

Step 1: Calculate the discount amount.

Discount Amount = 12% of $1200

Discount Amount = 0.12 * $1200

Discount Amount = $144

Step 2: Subtract the discount amount from the original price to get the selling price.

Selling Price = Original Price - Discount Amount

Selling Price = $1200 - $144

Selling Price = $1056

So, the selling price after applying a discount of 12% to goods bought for $1200 is $1056.

Consecutive integers x and y with x < y have opposite parity because when one integer is even, the other must be odd, ensuring they are never both even or both odd.

To prove this statement, let's analyze even and odd integers. An even integer is defined as any integer that can be expressed as 2n, where n is an integer. An odd integer is defined as any integer that can be expressed as 2n + 1, where n is an integer.

Let x be an integer. If x is even, it can be expressed as 2n. The next consecutive integer, y, will be x + 1, which can be expressed as 2n + 1, making y odd. Conversely, if x is odd, it can be expressed as 2n + 1. The next consecutive integer, y, will be x + 1, which can be expressed as (2n + 1) + 1 = 2(n + 1), making y even.

Therefore, if x and y are consecutive integers with x < y, they will always have opposite parity.

The height down the wall, in centimeters that the ladder slipped would be 28. 61 cm.

To indicate the ladder's heights before and after slipping as h1 and h2, respectively, is imperative. The ladder maintains a constant length of 3 meters (300 cm) throughout the occurrence.

At first, the ladder's foot stands at a distance of 60 cm from the base of the wall. However, following its slip, the same foot travels an additional 80 cm further away, creating an increased gap between it and the base of the wall, totaling to 140 cm.

The determination of the initial and final heights can be achieved through relying on the Pythagorean theorem:

300 ² = h2² + 140 ²

h2 ² = 300 ² - 140 ²

h2 = 265. 33 cm

The number of line segments whose two ends are two non-consecutive vertices of this polygon is 170

To find the number of line segments whose two ends are two non-consecutive vertices, we can first find the total number of line segments possible by selecting any two vertices.

For a polygon with n vertices, the number of ways to select two vertices is given by the binomial coefficient nC2, which is n(n-1)/2.

For this polygon with 20 vertices, the number of line segments possible is 20(20-1)/2 = 190.

However, we must subtract the number of line segments that connect consecutive vertices (sides of the polygon) since we only want non-consecutive vertices.

Since there are 20 sides, there are 20 line segments that connect consecutive vertices.

Therefore, the number of line segments whose two ends are two non-consecutive vertices of the polygon is 190 - 20 = 170.

So, the answer is (b) 170.

P(s = 1) = np(1-p)

The random variable s = xy can take on the values 0 or 1, depending on the values of x and y. We want to find the probability distribution of s.

We can start by finding the probability mass function (PMF) of s. For s = 0, we have:

P(s = 0) = P(xy = 0) = P(x = 0) + P(y = 0)

where the second equality follows from the fact that x and y are independent, so P(xy = 0) = P(x = 0)P(y = 0).

Using the PMF of x and y, we have:

P(s = 0) = P(x = 0) + P(y = 0)

= (1-p)^n + (1-p)

For s = 1, we have:

P(s = 1) = P(xy = 1) = P(x = 1)P(y = 1)

Using the PMF of x and y, we have:

P(s = 1) = P(x = 1)P(y = 1)

= np(1-p)

Therefore, the PMF of s is:

[tex]P(s = 0) = (1-p)^n + (1-p)[/tex])

P(s = 1) = np(1-p)

This distribution is called a mixture distribution, which is a combination of the Bernoulli and binomial distributions. We can see that when p = 0, s is always equal to 0, and when p = 1, s follows a binomial distribution with parameters n and p. When 0 < p < 1, s has a nontrivial mixture distribution.

To find the angle θ between the telephone line and the pole, we need to find the slope of the tangent to the catenary at the point where it meets the pole.

The slope of the tangent to the catenary at any point (x, y) is given by:

dy/dx = sinh(x/13)

At the pole, x = 0, and y = 13 - 8 = 5. So, the slope of the tangent to the catenary at the pole is:

dy/dx = sinh(0/13) = 0

This means that the tangent to the catenary at the pole is horizontal.

The angle θ between the telephone line and the pole is the angle between the horizontal and the line. So, we need to find the slope of the line.

The equation of the line passing through the two poles is:

y = mx + c

where m is the slope of the line and c is the y-intercept.

We know that the two poles are 14 m apart, so the x-coordinate of the second pole is 14. Let the y-coordinate of the second pole be y2. Then we have:

y2 = 13 cosh(14/13) - 8 = 45.685

The coordinates of the two poles are (0, 5) and (14, y2).

The slope of the line passing through these two points is:

m = (y2 - 5) / 14 = (45.685 - 5) / 14 = 2.913

So, the angle θ between the telephone line and the pole is:

θ = arctan(m) = arctan(2.913) = 1.234 radians = 1.234 * (180/π) ≈ 70.694 degrees (to 3 decimal places)

Therefore, the angle between the telephone line and the pole is approximately 70.694 degrees.

The distance AB is 2√2 units.

The distance ST is 4√2 units.

Distance between two points is the length of the line segment that connects the two points in a plane.

The formula to find the distance between the two points is usually given by d=√((x₂ – x₁)² + (y₂ – y₁)²)

For AB. We have:

A(1, 0) : x₁ = 1 , y₁ = 0

B(3, -2) : x₂ = 3 , y₂ = -2

d = √((3 – 1)² + (-2 – 0)²)

d = √8

d = √(4 * 2)

d = √4 * √2

d = 2 * √2

d = 2√2

Thus, the distance AB is 2√2

For ST. We have:

S(2, 3) : x₁ = 2 , y₁ = 3

T(6, -1) : x₂ = 6 , y₂ = -1

d=√((6 – 2)² + (-1 – 3)²)

d = √32

d = √(16 * 2)

d = √16 * √2

d = 4 * √2

d = 4√2

Thus, the distance ST is 4√2

Answer: 3.5 units

Step-by-step explanation:

We can count how many units the 2 points are away from each other and get 3.5

Or we can use the origin as a reference point, and since (-3,0) is 3 units away, and (0.5,0) is 0.5 units away. Adding the distances gives us 3.5 units
