The areas in ascending order are: 0.004 m² (or 40 cm²), 3.7 cm², 41 cm², and 420 mm² (or 0.42 cm²).

What is an ascending order?

Ascending order is the arrangement of a set of numbers or data in a sequence from smallest to largest. It is a way of organizing data in increasing numerical or alphabetical order. For example, the numbers 1, 2, 3, 4, 5 in ascending order is a sequence where each number is greater than the previous one. Similarly, arranging words in alphabetical order from A to Z is also an example of ascending order.

The areas in ascending order are:

0.004 m² = 40 cm²

3.7 cm²

41 cm²

420 mm² = 0.42 cm²

So, the areas in ascending order are: 0.004 m² (or 40 cm²), 3.7 cm², 41 cm², and 420 mm² (or 0.42 cm²).

Applying the triangle proportionality theorem, the length of AD that will make DE║AB is: AD = 60.

According to the triangle proportionality theorem, the equation or proportion we can create to find x is expressed as:

(2x - 4) / 5x = 3x / 8x

Cross multiply:

8x(2x - 4) = (3x)(5x)

16x² - 32x = 15x²

x² - 32x = 0

Solve to find x by factoring:

The equation x² - 32x = 0 can be solved by factoring:

x(x - 32) = 0

So either x = 0 or x - 32 = 0, meaning x = 32.

The solutions to the equation are x = 0 and x = 32.

Using x = 32:

AD = 2x - 4 = 2(32) - 4

The vertex focus of the parabola is (3,15) and the directrix is x=3.

1. Rewrite the equation in the form y = a(x - h)^2 + k

y = x^2 - 6x + 15

y = 1(x - 3)^2 + 15

2. The vertex focus is (h, k) = (3, 15)

3. The directrix is x = h = 3

By rewriting the equation in the form of y = a(x - h)^2 + k, we can find the vertex focus and directrix of the parabola. The vertex focus of a parabola is the point at which the graph changes direction, and is equal to (h, k). The directrix is the line at which the vertex focus is located, and is equal to x = h. For this equation, h = 3 and k = 15, so the vertex focus is (3, 15) and the directrix is x = 3.

When two consecutive words in a sequence have the same difference, the sequence is said to be arithmetic. The sequence is geometric if the quotient between related terms is the same.  

For item a:

When x increases by 1, y is multiplied by 2, hence, as the quotient between consecutive terms is the same, the data is a geometric sequence.

For Item b:

The recursive formula for a geometric sequence with a common ratio  and the first term  is given by:

f(n) = f(n-1)* q ^n-1, f(1) = a

The solution for the inequality is x∈(-∞,4)U(1,+∞)

What is inequality?

Inequality is a statement that compares two values and states that one value is greater than, less than, or not equal to the other value.

To solve the inequality (x-4)(x-1)>0, we can first factor it:

(x-4)(x-1)>0

We can then use the Zero Product Property, which states that if the product of two factors is equal to zero, then at least one of the factors must be equal to zero.

So we get:

x-4=0 or x-1=0

x = 4 or x = 1

Now we will test the sign of inequality for x-4 and x-1.

The side that is opposite to the 60° angle, BC = y × √3 = y√3 will be the medium length.

What is angle ?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

A 30-60-90 triangle is a special triangle since the length of its sides is always in a consistent relationship with one another.

In the below-given 30-60-90 triangle ABC, ∠ C = 30°,∠ A = 60°, and ∠ B = 90°. We can understand the relationship between each of the sides from the below definitions:

The side that is opposite to the 30° angle, AB = y will always be the smallest since 30° is the smallest angle in this triangle

The side that is opposite to the 60° angle, BC = y × √3 = y√3 will be the medium length because 60° is the mid-sized degree angle in this triangle

On the side that is opposite to the 90° angle, the hypotenuse AC = 2y will be the largest side because 90° is the largest angle.

The polynomial 2x^3 - 3x^2 x 5 is known as a cubic polynomial.

A cubic polynomial is a polynomial of degree 3, or a polynomial with the highest power of x being 3. This means that the formula for a cubic polynomial can be written as ax^3 + bx^2 + cx + d, where a, b, c, and d are all constants.

In the example of 2x^3 - 3x^2 x 5, the coefficients are 2, -3, 0, and 5 respectively. To calculate the value of the cubic polynomial, one must substitute a value of x into the equation. For example, if x = 2, then the equation would be 2(2^3) - 3(2^2) x 5, which simplifies to 32 - 24 x 5, or 32 - 120, which equals -88.
