The square root of 9 is how much less than 9 squared? : *
A) 0
B) 3
C) 6
D) 78
Answers
The square root of 9 is 78 less than 9 squared
The square root of 9 is calculated as
√9 = √(+ 3)² or√(- 3)²
= + 3 or - 3
Let's calculate the square of 9:
9² = 81
We need to calculate here, how much the square root of 9 is less than the square of 9 or we can say the difference between the square of 9 and the square root of 9. So, let's say that difference is denoted by d
d = 9² - √9
When √9 = +3
d = 81 - 3
d = 78
When √9 = -3
d = 81 - (-3)
d = 81 + 3
d = 84
Hence, the value of the difference between the square of 9 and the square root of 9 is 78 or 84.

The prize money from a game show is shared amongst the team in the ratio
A: B: C = 2: 5: 3. If the prize money was £1500, how much more money does person B receive than person A?
(b) Person C donates 40% of his share to charity. State the ratio of the amount
donated to charity, to the total prize money in its simplest form
Answers
Step-by-step explanation:
(a)
2:5:3 means that there are 2+5+3 = 10 units of the price money distributed between the team.
£1500 / 10 = £150 per unit.
person A gets therefore 2×150 = £300
person B gets 5×150 = £750
person C gets 3×150 = £450
so, person B gets 750-300 = £450 more money than person A.
(b)
40% of £450 = 450×0.4 = £180

The coordinates of the points A and B, after scaling becomes

What is scaling? How is it done?Scaling is defined as the process of changing the dimensions of the original figure as per some specific proportional rule.If the initial length is equivalent to {a}. Then, after the scaling by the scale factor of {K}, the length becomes {Ka}. Similarly, if the initial coordinates are (x, y) then after scaling the coordinates would be {Kx, Ky}.Scale factor is a dimensionless quantity that tells by how much time a specific dimension of a figure is enlarged or reduced. Mathematically, it is the ratio of two similar quantities. In case of length scaling, we can write -{K} = L{final}/L{initial}
Given is that shape is being enlarged using a scale factor of 2 and centre (6, 3).
Assume the coordinates of the point are A(x, y) and B(x₁, y₁). After scaling, the coordinates will become -
A(x, y) → A'(2x, 2y)
B(x₁, y₁) → B'(2x₁, 2y₁)
Therefore, the coordinates of the points A and B, after scaling becomes

A rectangular monitor’s size is measured diagonally from one corner to the opposite corner. What is the size of rectangular monitor that is 30 centimeters wide by 24 centimeters hight, to the nearest centimeter?
Answers
Answer: 38.3 cm
Step-by-step explanation:
To find the size of a rectangular monitor measured diagonally, you can use the Pythagorean theorem. The Pythagorean theorem states that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Here are the steps to calculate the diagonal size of the monitor:
Find the length of the hypotenuse by finding the square root of the sum of the squares of the other two sides.The other two sides of the triangle are the width and height of the monitor, which are given as 30 centimeters and 24 centimeters respectively.Apply the formula √(30² + 24²) = √(900+576) = √1476Take the square root of 1476 which is approximately 38.3 cm.Therefore, the size of the rectangular monitor that is 30 centimeters wide by 24 centimeters high is approximately 38.3 cm. to the nearest centimeter.
The size of the given mirror as a rectangular diagonal is 38.41 cm which is almost 39 cm.
We know that;
d=√ {(l)^2 + (w)^2}.........(i), where,
d= diagonal of the rectangle,
l= length of the rectangle = 30 cm
w= width of the rectangle = 24 cm.
Therefore, Substituting the values of each in equation (i), we get;
d=√{(30)^2+(24)^2} cm,
or, d = 38.41 cm
So, the size of the rectangular mirror measured diagonally is 38.41 cm which is almost 39 cm.

Answers
The solution to the given differential equation is a 3-dimensional vector function which satisfies the given initial conditions. The vector function consists of three components, one for each dimension in the equation.
The given differential equation is a 3-dimensional vector equation, of the form ()=⟨12−12,2−1,1⟩. The initial conditions are (1)=⟨0,0,12⟩ and ′(1)=⟨8,0,0⟩. The solution to this equation is a 3-dimensional vector function, ()=⟨, ,⟩. The first component of the vector function is a function of the independent variable, and must satisfy the initial condition (1)=⟨0,0,12⟩. This means that the first component of the vector function must be equal to 0 at x=1. The second component must satisfy the initial condition ′(1)=⟨8,0,0⟩. This means that the second component of the vector function must be equal to 8 at x=1. The third component of the vector function must also satisfy the initial condition (1)=⟨0,0,12⟩. This means that the third component of the vector function must be equal to 12 at x=1. Once the initial conditions have been satisfied, the equation can be solved to find the vector function.

Part A
Write a percent equation that represents the relationship of the height of the first copy to the height of the original photo.
Part B
Lyndie wants to make another copy that will have a height of 17 cm. The copy machine settings increase or decrease in increments of 5%. Which photo should she make her copy from, the original or her first copy? Explain.
Answers
a) The enlargement needed to be done is 25%.
b) The succession time should be at least t=9 to get a final copy that is less than 15% of the original size.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Let the size of the page be q, when it is reduced to 80%, its size becomes
= 80% x q
= 0.80(q)
= 0.80q
When you want to return it into its original size q,
x(0.80q) = q
x = q / 0.80q
x = 1.25
x= 125%
Hence, the enlargement needed to be done is 25%.
b) The size of the page after t number of copying done is given by
C(t) = [tex]C_0(0.80)^t[/tex]
So, C(t) / [tex]C_0[/tex] = [tex](0.80)^t[/tex]
0.15 ≤ [tex](0.80)^t[/tex]
Taking log on both side
log (0.15) ≤ log [tex](0.80)^t[/tex]
log (0.15) ≤ t log (0.80)
log (0.15) /log (0.80) ≤ t
0.80 ≤ t
Hence, the succession time should be at least t = 9 to get a final copy that is less than 15% of the original size.

The given equation about an arithmetic sequence is
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n-1) d ; n > 1
Boole's inequality(or the union bound) states that for any at most countable collection of events, the probability that at least one of the events happens is no greater than the sum of the probabilities of the events in the collection.
The objective is to prove the statement using principle of mathematical induction.
The principle of mathematical induction statement that a statement [tex]p_{n}[/tex] about positive integer n, is true if satisfies the following two conditions:

Distribute the constants on both sides of the equation:
x - 5/10 - 2(x - 3)/5 = 3(x - 4)/15
x - 5/10 - 2x + 6/5 = 3x - 12/15
Combine like terms on both sides of the equation:
-1.5x + 6/5 = 3x - 12/15
Subtract 3x from both sides of the equation:
-4.5x + 6/5 = -12/15
Add 12/15 to both sides of the equation:
-4.5x + 18/15 = 0
Divide both sides of the equation by -4.5:
x = -18/15 / -4.5
Simplify the result:
x = 4/3

The equation in slope intercept form is : [tex]y = \frac{1}{8} x - 223.05[/tex]
The slope intercept form is a process used to determine the equation of a straight line in the coordinate plane. It can be used to determine the equation of a line when given the slope of the straight line and the y-intercept
The slope-intercept form of a line is:
y = mx+b
where m is the slope of the line and b is an intercept of the y-axis.
[tex]m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
[tex]m = \frac{26.7 - 23.2 }{1998- 1970}[/tex]
[tex]m = \frac{1}{8}[/tex]
So,
[tex]y = \frac{1}{8} x + b[/tex]
To find b we get the point (1970, 23.2) and introduce it in the previous equation.
[tex]23.2= \frac{1}{8} (1970)+ b[/tex]
⇒ 23.2 - 246.25 = b
⇒ b = - 223.05
Then, the equation is : [tex]y = \frac{1}{8} x - 223.05[/tex]
