(k-10h) (k+10h)

Step-by-step explanation:

k^2 - 100h^2

Rewriting as

k^2 - (10h)^2

We recognize this as the difference of squares

We know the difference of squares is factored as a^2 -b^2 = (a-b)(a+b)

(k-10h) (k+10h)

Answer:

(k-10h) (k+10h)

Step-by-step explanation:

(x)^2 = 8^2 + 6^2

or, x^2 = 64 + 36

or, x^2 = 100

or, x = √100

or, x = 10

The value of x is 10.

The recursive sequence that represents the sequence defined by the following explicit formula is given as follows:

A geometric sequence is a sequence of numbers where each term is obtained by multiplying the previous term by a fixed number called the common ratio q.

The explicit formula of the sequence is given as follows:

\(a_n = a_1q^{n-1}\)

In which \(a_1\) is the first term.

The first term and the common ratio for this problem is given as follows:

\(a_1 = -32, q = -\frac{1}{4}\)

The common ratio means that each term is the previous term multiplied by -1/4, hence the recursive formula is given as follows:

(a) Chin had 93.1 marbles after the game.

(b) The three children had a total of 271.44 marbles altogether.

Let's break down the problem step by step to find the answers:

Initial marbles

Before the game:

Let's assume Afiq had x marbles.

Bala had 1/6 fewer marbles than Afiq, so Bala had (x - 1/6x) marbles.

Chin had 3/5 as many marbles as Bala, so Chin had (3/5)(x - 1/6x) marbles.

After the game

After the game, Bala lost 20% of his marbles to Chin, so he has 80% (or 0.8) of his initial marbles remaining.

Afiq lost 2/3 of his marbles to Chin, so he has 1/3 (or 0.33) of his initial marbles remaining.

Calculating the marbles

(a) How many marbles did Chin have after the game?

To find Chin's marbles after the game, we add the marbles gained from Bala to Chin's initial marbles and the marbles gained from Afiq to Chin's initial marbles.

Chin's marbles = Initial marbles + Marbles gained from Bala + Marbles gained from Afiq

Chin's marbles = (3/5)(x - 1/6x) + 0.8(x - 1/6x) + 0.33x

Chin's marbles = (3/5)(5x/6) + 0.8(5x/6) + 0.33x

Chin's marbles = (3/6)x + (4/6)x + 0.33x

Chin's marbles = (7/6)x + 0.33x

We are given that Chin gained 105 marbles, so we can equate the equation above to 105 and solve for x:

(7/6)x + 0.33x = 105

(7x + 2x) / 6 = 105

9x / 6 = 105

9x = 105 * 6

x = (105 * 6) / 9

x = 70

Substituting the value of x back into the equation for Chin's marbles:

Chin's marbles = (7/6)(70) + 0.33(70)

Chin's marbles = 10(7) + 0.33(70)

Chin's marbles = 70 + 23.1

Chin's marbles ≈ 93.1

Therefore, Chin had approximately 93.1 marbles after the game.

(b) After the game, the 3 children each bought another 40 marbles. To find the total number of marbles the 3 children have altogether, we need to sum up their marbles after the game and the additional 40 marbles for each.

Total marbles = Afiq's marbles + Bala's marbles + Chin's marbles + Additional marbles

Total marbles = 0.33x + 0.8(x - 1/6x) + (7/6)x + 40 + 40 + 40

Total marbles = 0.33(70) + 0.8(70 - 1/6(70)) + (7/6)(70) + 120

Total marbles = 23.1 + 0.8(70 - 11.7) + 81.7 + 120

Total marbles = 23.1 + 0.8 × 58.3 + 201.7

Total marbles = 23.1 + 46.64 + 201.7

Total marbles = 271.44

The three children had a total of 271.44 marbles altogether.

True, an exponential growth function represents a quantity that has increased.

The mathematical expression f(x)=exp or e^x denotes the exponential function. The phrase typically refers to the positive-valued function of a real variable, unless otherwise specified.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

For example, if there is an exponential function represented as E = 5(10)³. It means that the function is increased by a number of times itself.

The perimeter of the rhombus in this problem is given as follows:

19.8 units.

The perimeter of a polygon is given by the sum of all the lengths of the outer edges of the figure, that is, we must find the length of all the edges of the polygon, and then add these lengths to obtain the perimeter.

The diagonal length can be obtained as follows:

RU + UT = 7.

Applying the Pythagorean Theorem, the side length is obtained as follows:

x² + x² = 7²

2x² = 49

\(x = \sqrt{\frac{49}{2}}\)

Step-by-step explanation:

1. The probabilities of Poison distribution are: \(P(0) = (e^{(-0.689)} * 0.689^0) / 0! = 0.5012\). \(P(1) = (e^{(-0.689)} * 0.689^1) / 1! = 0.3447\). \(P(2) = (e^{(-0.689)} * 0.689^2) / 2! = 0.1189\).

The Poisson distribution is a discrete probability distribution that defines the number of events that take place during a specific period of time or space, provided that they do so independently of one another and at a certain average rate. Siméon Denis Poisson, a French mathematician, invented it in the early 19th century to simulate the occurrence of uncommon events, such as horse kick fatalities in the Prussian army. He gave it his name.

The mean or expected value of the number of occurrences in the interval is represented by the Poisson distribution's single parameter, indicated by the Greek letter lambda.

The Poisson distribution is given as:

\(P(X = x) = (e^{(-\lambda)} * \lambda ^x) / x!\)

Now,

a. For P(0) we have:

λ = (total number of homicides) / (total number of city-years)

= 193 / 280 = 0.689

Substituting the values of  λ = 0.689 and x = 0 we have:

\(P(0) = (e^{(-0.689)} * 0.689^0) / 0! = 0.5012\)

b. For P(1), we can plug in λ = 0.689 and x = 1 :

\(P(1) = (e^{(-0.689)} * 0.689^1) / 1! = 0.3447\)

c. For P(2), we can plug in λ = 0.689 and x = 2:

\(P(2) = (e^{(-0.689)} * 0.689^2) / 2! = 0.1189\)

d. For P(3), we can plug in λ = 0.689 and x = 3:

\(P(3) = (e^{(-0.689)} * 0.689^3) / 3! = 0.0272\)

e. P(4), we can plug in λ = 0.689 and x = 4:

\(P(4) = (e^{(-0.689)} * 0.689^4) / 4! = 0.0047\)

2 ) The comparison for the actual and distributed values is:

Expected 0 homicides: 0.5012 * 280 ≈ 140.35

Expected 1 homicide: 0.3447 * 280 ≈ 96.72

Expected 2 homicides: 0.1189 * 280 ≈ 33.32

Expected 3 homicides: 0.0272 * 280 ≈ 7.62

Expected 4 homicides: 0.0047 * 280 ≈ 1.31
