his finger?
b. What type of transformation is used to pass the basketball?
Answers
The types of transformations that occur as a result of the motion on the ball are;
A) Rotation
B) Translation
What is the type of transformation?Transformation is a method required to resize or change the orientation of a given shape or figure. The types of transformation are translation, reflection, rotation, and dilation.
Translation is a method of transformation that involves moving an object or shape from one point to another without changing any dimension.
Reflection is a method of transformation that involves flipping a given figure about a given reference point or line. In order words, a mirror image of the original object.
Rotation is a method of transformation that involves turning a given figure at an angle about a reference point.
Dilation is a method of transformation whereby the length of the sides of the figure is either increased or decreased.
A) When James spins a basketball on his finger, it is clear that this transformation is rotation because it involves turning the ball at an angle about a given point.
B) When James passes the basketball, the transformation would be translation because it involves moving the ball from one point to another without changing the dimension of the ball.

Answers
The numbers are:
1. The value of x = 5
2. The value of x = 15 or 8 and y = 8 or 15
What is Square?
The word Square means a number multiplied by itself.
The above answers were gotten in the following way:
1. Let the unknown negative number be x
The square of the negative number: x² is
Sixteen more than six times of negative x: 6x+16
It is written as: (x)²=6x+16
Equating to zero, we have:
x²-6x-16=0
Factorizing, we have:
x²-8x+2x-16=0
x(x-8)+2(x-8)=0
x+2=0 and x-8=0
x=-2 and 8
Since the number is negative, x = -2
Therefore, the value of the negative number is -2
2. Given:
Sum of two numbers = 23
Product of two numbers = 120
Calculation:
Let the two numbers be x and y
x+y=23...............equation 1
xy=120..................equation 2
From equation 1, x=23-y
Substitute the value of x in equation 2, we have:
(23-y)y=120
Opening the brackets, we have:
23y-y²=120
Rearranging the equation, we have:
-y²+23y=120
Equating to zero, we have:
-y²+23y-120=0
Multiplying both sides by (-1), we have:
y²-23y+120 = 0
Factorizing, we have:
y²-15y-8y+120=0
y(y-15)-8(y-15)=0
(y-8)(y-15)=0
y=8 or 15
Substituting the values of y in any of the equation. Choosing equation 1, we have:
From Equation 1: x+y=23
When y=8,
x+8=23
x=23-8
x=15
When y=15
x+15=23
x=23-15
x=8
Therefore the values of the two numbers are 15 and 8

Brief history of triangle numbers
What is Triangle Number?
An equilateral triangle-shaped group of objects is counted using a triangular number or triangle number. Square and cube numbers are two further examples of figurate numbers, which also include triangle numbers.
Students are typically introduced to triangular numbers through the account of Carl Gauss, a well-known mathematician who used the concept of the triangle number formula to aid him with summing consecutive integers as a student. This tale and its applications in many situations are discussed in the article Clever Carl.
Triangular numbers were created by the Pythagoreans, who discovered connections between geometric forms and numbers, giving rise to triangular, square, pentagonal, and other numbers.
After four or five terms, students may recognize that the answer can be discovered by adding consecutive terms, according to our research. As an illustration, you may use the formulas 1+2+3+4+5 or 10 (the preceding term) + 5 to determine the fifth term. However, when students attempt to transition from this to the general formula for triangle numbers of
n(n+1)/2
Drawing triangle numbers is an exercise that could be helpful in establishing a connection between these two concepts.
The nth term and substitution into algebraic expressions can then be discussed using this formula. Sequences, notably quadratic sequences, can also be discussed.

Okay, here we have this:
Considering the provided information, and that the area of a rectangle is the product of its length and width, we obtain the following:
[tex]\begin{gathered} Width=\frac{Area}{Length} \\ Width=\frac{9h^2+45h+36}{3h+12} \\ =\frac{9\left(h+1\right)\left(h+4\right)}{3h+12} \\ =\frac{9\left(h+1\right)\left(h+4\right)}{3\left(h+4\right)} \\ =3\mleft(h+1\mright) \\ =3h+3 \end{gathered}[/tex]Now, to know if the width is greater or less than the length, we will subtract it, then we have:
[tex]\begin{gathered} (3h+12)-(3h+3) \\ =3h+12-3h-3 \\ =12-3 \\ =9 \end{gathered}[/tex]Finally we obtain that the width is feet 9 shorter than the length, so the correct answer is the option B

Answers
A percentage is a number or ratio that represents a fraction of 100.
If there is a trade discount of 45% on the price of the merchandise of $5900, the net price of the merchandise is $3245.
What is a percentage?A percentage is a number or ratio that represents a fraction of 100.
We have,
Merchandise price = $5,900
Discount rate = 45%
45% = 45/100 = 9/20
The net price of the merchandise:
= 5900 - (45% of 5900)
= 5900 - 9/20 x 5900
= 5900 - 9 x 295
= 5900 - 2655
= 3245
Thus,
If there is a trade discount of 45% on the price of the merchandise of $5900, the net price of the merchandise is $3245.

Given the following sequences: I. 2,4,6,8,10... II.2,4,8,16,32... III. a,a + 2, a + 4, a + 6, a +8... Which ones are arithmetic sequences?
Answers
ANSWER
The arithmetic sequences are: I and iii
EXPLANATION
The formula for the nth term of an arithmetic sequence is:
[tex]a_n=a_1+d(n-1)[/tex]where a1 is the first term of the sequence and d is the common difference.
For the first sequence I. 2, 4, 6, 8, 10... we can find the common difference by subtracting the first term from the second:
[tex]\begin{gathered} a_2=a_1+d(2-1) \\ a_2=a_1+d \\ d=a_2-a_1 \\ d=4-2 \\ d=2 \end{gathered}[/tex]So the nth term of this sequence is:
[tex]a_n=2+2(n-1)[/tex]Each term of this sequence follows this rule. Therefore this is an arithmetic sequence.
For the second sequence II. 2, 4, 8, 16, 32... there's no common difference because between the first and second term there's a difference of 2, between the second and third there's a difference of 4, and this increases as we move through the sequence. Therefore this is not an arithmetic sequence.
For the third one, III. a, a+2, a+4, a+6, a+8... we can see that there is a common difference:
[tex]\begin{gathered} a_2_{}_{}=a_1+d(2-1) \\ d=a_2-a_1 \\ d=a+2-a \\ d=2 \end{gathered}[/tex]The rule for the nth term is:
[tex]a_n=a+2(n-1)[/tex]Let's find the first 5 terms:
[tex]\begin{gathered} a_1=a+2(1-1)=a \\ a_2=a+2(2-1)=a+2 \\ a_3=a+2(3-1)=a+4 \\ a_4=a+2(4-1)=a+6 \\ a_5=a+2(5-1)=a+8 \end{gathered}[/tex]This shows that each term follows the same rule. Therefore this is an arithmetic sequence.

A Christmas tree is supported by a wire that is 3 meters longer than the height of the tree. The wire is anchored at a point whose distance from the base of the tree is 21 meters shorter than the height of the tree. What is the height of the tree?
Answers
The height of the Christmas tree is 12 meters
How to determine the height of the Christmas tree?Represent the height of the tree with h
So, we have the following parameters
Tree height = hBaseline = h - 21Anchor = h + 3The figure that illustrates the above parameters is added as an attachment
From the figure, we have the following equation by Pythagoras theorem
(h + 3)² = h² + (h - 21)²
Expand the exponents
h² + 6h + 9 = h² + h² - 42h + 441
Evaluate the like terms
6h + 9 = h² - 42h + 441
So, we have
h² - 48h + 432 = 0
Expand
h² - 36h - 12h + 432 = 0
Factorize the equation
(h - 36)(h - 12) = 0
Solve for h
h = 36 and h = 12
When h = 36, the baseline will be negative
So, we make use of h = 12
Hence, the tree has a height of 12 meters

Probability is a discipline of mathematics that deals with statistical models of how probable an event is to exist or how likely a statement is to be true. The probability of an occurrence is a value between 0 and 1 and 1, where 0 denotes the event's impossibility and 1 represents certainty. The greater the likelihood of an occurrence, the more probable it will occur. Tossing a fair (unbiased) coin is a basic example. Because the coin is fair, the two possibilities ("heads" and "tails") are equally likely; the chance of "heads" equals the probability of "tails," and because no other outcomes are possible, the probability of either "heads" or "tails" is 1/2.
