Which of the following types of polynomials is 2x3 − 3x2 x 5?
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.
Therefore, when x = 2, the polynomial 2x^3 - 3x^2 x 5 equals -88. This can be further verified by graphing the polynomial and observing the point (2, -88).

What is Function ?Each element of X receives precisely one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.
The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The whole set of values that the function's output can produce is referred to as the range. The collection of values that might result in a function's outputs is known as the co-domain.
The function
f(x) = 8x - 3
Evaluating
f(0) = 8 *0 - 3 = -3
f(4) = 8*4 -3 = 29
f(-4) = 8*(-4) -3 = -35

C. She will need a time of 1024 units to complete the 10th station.
What is the difference between arithmetic and geometric sequence?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
for our case
f(n) = f(n-1)* 2 ^n-1, f(1) = 2
For Item c:
The explicit formula for a geometric sequence with a common ratio and the first term is given by:
an = a1 q^n-1
Hence, in this question:
an = 2(2)^n-1 = 2^n

Applying the triangle proportionality theorem, the length of AD that will make DE║AB is: AD = 60.
How to Apply the Triangle Proportionality Theorem?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.

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.

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.

angles 1 and G are a linear pair and sum to 180° , that is
∠ 1 + ∠ G = 180°
121° + ∠ G = 180° ( subtract 121° from both sides )
∠ G = 59°
