The correct answer is (d) No, quadrilaterals LMNO and PQRS are not similar because their corresponding sides are not proportional.

A quadrilateral is a geometric shape with four sides and four corners.

To be classified as a quadrilateral, its shape must be a closed figure with four straight sides and four interior angles. 

To determine quadrilaterals are similar, we need to check if corresponding angles are congruent and corresponding sides are proportional.

Checking corresponding angles are congruent:

∠ L  to ∠P.

∠M  to ∠Q.

∠ N  to ∠ R.

∠O  to ∠S.

All corresponding angles are congruent. Therefore, quadrilaterals have the same shape.

Check if corresponding sides are proportional.

LM =√((-1 - (-2))² + (4 - 2)²) = √(2² + 2²) = 2√2

MN = √((3 - (-1))² + (4 - 4)²) = √(4²) = 4

NO = √((4 - 3)² + (2 - 4)²) = √(2² + 2²) = 2√(2)

OL = √((-2 - 4)² + (2 - (-6))²) = √(6² + 8²) = 10

PQ = √((4 - 2)² + (-2 - (-6))²) = √(2² + 4²) = 2√5

QR = √((12 - 4)² + (-2 - (-2))²) = √(8²) = 8

RS = √((15 - 12)² + (-6 - (-2))²) = √(3² + 4²) = 5

SP = √((2 - 15)² + (-6 - (-6))²) = √(13²) = 13

LM / PQ = (2√2) / (2√5) = √(8/5)

MN / QR = 4 / 8 = 1/2

NO / RS = (2√(2)) / 5√(1) = (2/5)√(2)

OL / SP = 10 / 13

The corresponding sides are not proportional because they are not all equal or proportional to each other. Therefore, we can conclude that the quadrilaterals LMNO and PQRS are not similar.

Answer:

To write the cubic polynomial function f(x) in expanded form with zeros −6, −5, and −1, we can use the factored form of a cubic polynomial. The factors of this polynomial are (x + 6), (x + 5), and (x + 1) . Therefore, the cubic polynomial function f(x) in factored form is f(x) = a(x + 6)(x + 5)(x + 1). We also know that f(0) = 60. Substituting x = 0 in the equation gives us: f(0) = a(6)(5)(1) = 30a. Therefore, a = 2. Substituting this value of a in the factored form of the polynomial gives us: f(x) = 2(x + 6)(x + 5)(x + 1). Expanding this expression gives us the cubic polynomial function f(x) in expanded form with zeros −6,−5,and −1 as: f(x) = 2x^3+14x^2+11x-60

Step-by-step explanation:

f(x) = 2 (x+6)(x+5)(x+1) .

Added multiplier 2 because 6×5×1 = 30. But it's given that f(0) = 60.

f(x) = 2x³ + 24 x² +82 x 60

Step-by-step explanation:

We can use the market-to-book ratio to calculate the company's market price per share.

Market-to-book ratio = Market value per share / Book value per share

Book value per share = Shareholder equity / Number of shares outstanding

We are given the market-to-book ratio as 2.60, and the shareholder equity as R1000 000. We can calculate the book value per share as follows:

Book value per share = R1000 000 / Number of shares outstanding

To calculate the number of shares outstanding, we can use the earnings per share (EPS) formula:

EPS = Earnings / Number of shares outstanding

We are given the earnings per share as R2.50, and the earnings after interest and taxes as R600 000. Substituting these values, we get:

R2.50 = R600 000 / Number of shares outstanding

Solving for Number of shares outstanding:

Number of shares outstanding = R600 000 / R2.50 = 240,000 shares

Now, we can calculate the book value per share:

Book value per share = R1000 000 / 240,000 = R4.17 per share

Finally, we can calculate the market value per share using the market-to-book ratio:

Market-to-book ratio = Market value per share / Book value per share

2.60 = Market value per share / R4.17

Market value per share = 2.60 x R4.17 = R10.83 per share

Therefore, the company's market price per share is R10.83.

the correct option for this question is  (a) e < 53.

Why it is?

The inequality that represents Natasha's earnings, e, from any of the companies she interviewed with is:

e < 53.5

This is because her projected earnings per hour range from $25.13 to $53.5, and the maximum value is $53.5. So, her earnings from any of the companies cannot be greater than $53.5 per hour. Therefore, the correct answer is option (a) e < 53.

Earnings are the amount of money that a person earns from their work, business, investments, or other sources of income. This can include salaries, wages, commissions, bonuses, and profits, among others.

Earnings are typically reported as gross income, which is the total amount earned before taxes and other deductions are taken out. It is an important measure of a person's financial well-being and is often used to determine eligibility for credit or loans. Earnings can vary widely depending on a person's job, level of experience, education, and industry, among other factors.

Answer:

Let's denote the duration of each episode of Lola's podcast by "L" and the duration of each episode of Franco's podcast by "F".

From the information given, we can write two equations based on the total duration of content for the two years:

17L + 43F = 5,645 (equation 1)

36L + 43F = 6,956 (equation 2)

To solve for L and F, we can eliminate F by subtracting equation 1 from equation 2:

(36L + 43F) - (17L + 43F) = 6,956 - 5,645

Simplifying, we get:

19L = 1,311

Therefore, the duration of each episode of Lola's podcast (L) is:

L = 1,311 / 19

L ≈ 69.0 minutes

To find the duration of each episode of Franco's podcast (F), we can substitute the value of L into either equation 1 or 2:

17L + 43F = 5,645

17(69.0) + 43F = 5,645

1,173 + 43F = 5,645

43F = 4,472

F = 4,472 / 43

F ≈ 104.0 minutes

Therefore, each episode of Lola's podcast is approximately 69.0 minutes long, and each episode of Franco's podcast is approximately 104.0 minutes long.

1. ƒ is one-to-one and f(0) = 7, then f⁻¹(7) = 0 and (f(0))⁻¹ = 1/7. 2. A domain on which ƒ is one-to-one and non-decreasing is (4, ∞).

In mathematics, a function is a relation between two sets of elements, called the domain and the range, where each element in the domain is paired with a unique element in the range. The domain is the set of input values for the function, while the range is the set of output values.

A function is usually denoted by a symbol such as f, and is defined by a rule that assigns to each element in the domain a unique element in the range. This rule can be given in various forms, such as an algebraic expression, a graph, or a table of values.

For example, the function f(x) = 2x assigns to each input value x a unique output value that is twice the value of x. If we plug in x = 3, we get f(3) = 2(3) = 6, which means that 3 is mapped to 6 by the function f.

Question 1:

If ƒ is one-to-one and f(0) = 7, then f⁻¹(7) = 0 and (f(0))⁻¹ = 1/7.

Since ƒ is one-to-one, every element in the domain is mapped to a unique element in the range. This means that if f(0) = 7, then f⁻¹(7) = 0, which is the unique element in the domain that maps to 7.

Also, (f(0))⁻¹ = (7)⁻¹ = 1/7.

Therefore, f⁻¹(7) = 0 and (f(0))⁻¹ = 1/7.

Question 2:

Let f(x) = (x - 4)².

For f to be one-to-one and non-decreasing, the function must be strictly increasing or decreasing on its domain.

To find a domain on which ƒ is one-to-one and non-decreasing, we can take the derivative of ƒ and look at its sign:

f'(x) = 2(x - 4)

f'(x) is positive for x > 4, which means that ƒ is increasing on the interval (4, ∞).

Therefore, a domain on which ƒ is one-to-one and non-decreasing is (4, ∞).

x = (2n + 1)π/4

where n is an integer.

This is because the tangent function approaches infinite when 2x is an odd multiple of [tex]\pi[/tex]/2,

The tangent function, on the other hand, has vertical asymptotes at odd multiples of [tex]\pi[/tex]/2.

So the vertical asymptotes of g(x) in the range of x = [-90°; 90°] are:

x = -π/8, π/8, 3π/8, 5π/8, and 7π/8.

Examining the behavior of the tangent function as x approaches positive or negative infinity can reveal the horizontal asymptotes of the function g(x) = 3tan(2x).

As x approaches odd multiples of /2, the tangent function oscillates between positive and negative infinity, so no horizontal asymptotes exist.

As a result, in the given range, the formulae for the vertical asymptotes of the function g(x) = 3tan(2x) are:
