The price of an item that is normally £120 after a 20% discount is £96.

To find the price of an item that is normally £120 after a 20% discount,

Calculate the discount amount: To find the discount amount, multiply the original price (£120) by the discount rate ( 20% ) in decimal form:

Discount amount = Original price x Discount rate

= £120 x 0.2

= £24

Calculate the sale price: To find the sale price, subtract the discount amount from the original price:

Sale price = Original price - Discount amount

= £120 - £24

= £96

Therefore, the sale price is £96

The given facts about power sets: Statement 1: False, Statement 2: True, Statement 3: True.

Statement 1: The power set of X is a subset of X. False. The power set of X, denoted by P(X), is a set containing all subsets of X. However, X is not a subset of P(X).

Statement 2: The cardinality of P(X) is greater than the cardinality of X. True. Since the power set of X contains all subsets of X, it has a higher cardinality than X. This can be proven with the equation |P(X)| = 2^|X|.

Statement 3: The cardinality of the power set of the empty set is 1. True. The empty set, denoted by Ø, has no elements, and therefore the power set of the empty set, P(Ø), has one element, which is the empty set itself. Therefore, |P(Ø)| = 1.

Answer: Let's start by using algebra to solve the problem.

Let's call the width of the rectangle "w". Then we know that the length of the rectangle is twice the width, or "2w".

The formula for the perimeter of a rectangle is:

P = 2l + 2w

where P is the perimeter, l is the length, and w is the width.

We know that the perimeter is 18 inches, so we can substitute the values we have:

18 = 2(2w) + 2w

Simplifying:

18 = 4w + 2w

18 = 6w

Dividing both sides by 6:

w = 3

So the width of the rectangle is 3 inches.

To find the length, we can use the fact that it is twice the width:

l = 2w = 2(3) = 6

So the length of the rectangle is 6 inches.

Therefore, the rectangle is 6 inches long and 3 inches wide.

The perimeter of the quarter circle with radius 1 yard is approximately 2.57 yards.

To find the perimeter of a quarter circle, we need to add up the lengths of its curved edge and its straight edge.

In this case, the curved edge is a quarter of a circle with radius 1 yard. The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle. Since we only need a quarter of the circumference, we can divide the formula by 4:

C = (2πr)/4

Substituting r = 1, we get:

C = (2π(1))/4

C = π/2

Therefore, the curved edge of the quarter circle has a length of π/2 yards. The straight edge of the quarter circle is simply the radius, which is also 1 yard.

So the perimeter of the quarter circle is the sum of the curved edge and the straight edge:

Perimeter = (π/2) + 1

Using 3.14 for π and adding the two terms, we get:

Perimeter ≈ 2.57 yards

In conclusion, we need to identify the set of values of x for which either f(x)=-1/4 or f(-x)=-1/4 in order to solve to the equation f(|x|)=-1/4.

The expression f(|x|)=-1/4 indicates that the absolute value of x's function f is equal to 1/4. Any x values that satisfy this equation are what we are trying to find. We can rewrite the equation as f(x)=-1/4 when x is positive and f(-x)=-1/4 when x is negative because the absolute value of x is always positive.

We must search for values of x such that f(x)=-1/4 or f(-x)=-1/4 in order to identify the answers. Without knowing more about the function, f may be anything, hence we cannot know the precise solutions.

Therefore, we can state that x or -x is a solution to the equation if there is a value of x such that f(x)=-1/4 or f(-x)=-1/4.

As a result, we must identify the range of x values for which either f(x) or f(-x) = 1/4.

The length of BC is 6 units.

In geometry, the tangent is commonly used to describe the relationship between a circle and a straight line. A tangent line to a circle is a line that intersects the circle at exactly one point. This point of intersection is called the point of tangency. The tangent line is perpendicular to the radius of the circle at the point of tangency.

By the tangent-secant theorem, we have:

PB^2 = PA(PA + AB)

where AB is the length of the tangent segment from point A to the point of intersection of the secant with the circle.

Substituting the given values, we get:

4^2 = 8(8 + AB)

Simplifying and solving for AB, we get:

16 = 64 + 8AB

8AB = -48

AB = -6

Since AB is a length, it must be positive, so we take the absolute value:

AB = 6

Now we can use the secant-tangent theorem to find the length of BC:

PC(PC + BC) = PB^2

Substituting the given values and using the fact that PC = PA = 8, we get:

8(8 + BC) = 4^2

64 + 8BC = 16

8BC = -48

BC = -6

Again, since BC is a length, it must be positive, so we take the absolute value:

BC = 6

Therefore, the length of BC is 6 units.

we can write: x - (6 + ???? ) = 0Or, x = 6 + ????Now, Let's combine these two roots and write the polynomial in factored form.

i. The points of intesection of the common chords of the curve x² + y² = 4 and y² = 3x are

ii. The points of intesection of the common chords of the curve x² + y² = 4 and x² - 4y + 1 = 0 are

The common chords of circles are the chords that pass through the points of intersection of the curves.

i. Given the curve x² + y² = 4 and y² = 3x. We desire to find their points of intesection of the common chords. We proceeds as follows.

Since  x² + y² = 4 and y² = 3x. Substituting the second equation into the first, we have

x² + y² = 4 and y² = 3x.

x² + 3x = 4

Re-arranging, we have

x² + 3x - 4 = 0

Factorizing the quadratic equation, we have

x² - x + 4x - 4 = 0

x(x - 1) + 4(x - 1) = 0

(x + 4)(x - 1) = 0

⇒ x + 4 = 0 and x - 1 = 0

⇒ x = - 4 and x = 1

Now, y² = 3x.

⇒ y = ±√3x

So.substituting x = -4 into the equation, we have

y = ±√3x

y = ±√(3 × -4)

= ±√(-12)

Since the square root is negative, this answer is invalid.

Substituting x = 1 into y, we have

y = ±√3x

y = ±√3(1)

y = ±√3

So, the points of intersection are (1, √3) and (1,-√3)

ii. Given the curve x² + y² = 4 and x² - 4y + 1 = 0. We desire to find their points of intesection of the common chords. We proceeds as follows.

Since  x² + y² = 4 and x² - 4y + 1 = 0. From the second equation, we have

x² = 4y - 1

Substituting this equation into the first, we have

x² + y² = 4 and x² = 4y - 1

y² + 4y - 1 = 4

Re-arranging, we have

y² + 4y - 1 - 4 = 0

y² + 4y - 5 = 0

Factorizing the quadratic equation, we have

y² - y + 5x - 5 = 0

y(y - 1) + 5(y - 1) = 0

(y + 5)(y - 1) = 0

⇒ y + 5 = 0 and y - 1 = 0

⇒ y = - 5 and y = 1

Now, x² = 4y - 1

⇒ x = ±√(4y - 1)

So, substituting y = -5 into the equation, we have

x = ±√(4y - 1)

x = ±√[(4 × -5) - 1)]

= ±√(- 20 - 1)

= ±√-21

Since the square root is negative, this answer is invalid.

Substituting y = 1 into x, we have

x = ±√(4y - 1)

x = ±√(4(1) - 1)

x = ±√(4 - 1)

x = ±√3

So, the points of intersection are (√3, 1) and (-√3, 1)

There are 17 one-dollar coins and 19 two-dollar coins in the machine.

4.3.1 Model the statement into two linear equations by letting the number of one-dollar coins to be x and the number of two-dollar coins to be y:

Let x be the number of one-dollar coins and y be the number of two-dollar coins in the machine. Then we can form the following two linear equations:

Equation 1: x + y = 36 (total number of coins)

Equation 2: 1x + 2y = 55 (total value of coins)

4.3.2 Solve the two equations you formed in 4.3.1 using Cramer’s rule to find the number of coins of each value:

To solve the two equations using Cramer's rule, we need to write them in matrix form:

| 1 1 | | x | | 36 |

| | x | | |

| 1 2 | | y | | 55 |

Using Cramer's rule, we first calculate the determinant of the coefficient matrix:

D = | 1 1 |

| 1 2 |

D = (1 x 2) - (1 x 1) = 1

Then we replace the first column of the coefficient matrix with the constants from the right-hand side of the equations:

Dx = | 36 1 |

| 55 2 |

And calculate the determinant of this matrix:

Dx = (36 x 2) - (55 x 1) = 17

Similarly, we replace the second column of the coefficient matrix with the constants from the right-hand side of the equations:

Dy = | 1 36 |

| 1 55 |

And calculate the determinant of this matrix:

Dy = (1 x 55) - (1 x 36) = 19

Finally, we can calculate the values of x and y using the formulas:

x = Dx / D = 17 / 1 = 17

y = Dy / D = 19 / 1 = 19

Therefore, there are 17 one-dollar coins and 19 two-dollar coins in the machine.
