What is a polynomial?

A polynomial is a mathematical statement made up of coefficients and indeterminates that uses only the operations addition, subtraction, multiplication, and powers of positive integers of the variables.

We can now look into each polynomial.

a) x³ + 125

   125 is a cube of 5 and also  x³  is the power of x.

So this is a perfect cube.

b) 8p³ - 27

    8p³ is a perfect cube of 2p and 27 is a perfect cube of 3.

So it is a perfect cube.

c) 12x³-9

    This is neither a cube nor a square.

d) a²-100

   100 is a perfect square and so is a².

So this is a difference of perfect squares.

e) 4m² + 25

4m² is a square of 2m and 25 is a square of 5.

But the operator is +

So this is neither a cube nor a difference of a perfect square.

f) 16x²-9

16x² is a square of 4x and 9 is a square of 3.

Also, the operator is -

So this is a difference of perfect squares.

Therefore the above polynomials are discussed and grouped into each given category accordingly.

Answer:

The formula d2 + hw could be for an area. The formula is the sum of two terms, d2 and hw. The first term, d2, is the area of a square with side length d. The second term, hw, is the area of a rectangle with length h and width w. Therefore, the formula is for the total area of the square and the rectangle combined.

Step-by-step explanation:

To solve this equation for v, we need to get v by itself on one side of the equation. To do this, we can subtract 6 from both sides of the equation:

[tex]\displaystyle -\frac{5}{8} - 6= v \\\\-\frac{5}{8} - \frac{48}{8} =v\\\\-\frac{53}{8} =v[/tex]

To convert a fraction in the form of a/b to a mixed fraction, we can divide a by b and then write the quotient as the whole number part of the mixed fraction and the remainder as the numerator of the fractional part, with the denominator being the same as the denominator of the original fraction.

In this case, we have a/b = -53/8. To convert it to a mixed fraction, we can divide -53 by 8: -53/8 = -6 R 5

So, -53/8 as a mixed fraction is -6 5/8.

Two length of the same frequency and amplitude moving in opposite directions combine to form a standing wave, which appears to be stationary. Given that the pool in this instance is 24 m long and has six loops, the wavelength is 4 m.

Wavelength = Length of Pool / Number of Loops

24 m / 6 loops

= 4 m

Wavelength

= 4 m

Two waves of the same frequency and amplitude moving in opposite directions combine to form a standing wave, which appears to be stationary. A stationary wave pattern is produced when the two waves collide and interfere with one another. Six loops make up the 24 m-long pool in this instance. As a result, the standing wave's wavelength is equal to the pool's length divided by the number of loops, or 24 m / 6 = 4 m. This indicates that the standing wave's wavelength is 4 metres. Standing waves can be used to determine a wave's speed because they are equal to wavelength times frequency. Understanding how waves behave in various contexts, such as swimming pools, oceans, or other bodies of water, can be helped by this.

The measure of PRS is 70°, So correct option is D.

A circle is a two-dimensional geometric shape defined as the set of all points that are a fixed distance, called the radius, away from a given central point. Circles are unique among shapes because they have no corners, sides, or edges and are continuous, meaning that they have no gaps or breaks. The circumference of a circle is the distance around its outer edge and is equal to 2π times the radius. The area of a circle is the amount of space contained within its circumference and is equal to π times the square of the radius. Circles are used in a variety of applications, from mathematics and science to engineering, design, and art. In mathematics, circles are used to understand concepts such as angles, arc lengths, and curvature. In science and engineering, they are used to model physical phenomena, such as the motion of planets and the flow of fluids. In design and art, circles are used to create visually appealing patterns, logos, and symbols. The circle is considered a symbol of unity, wholeness, and completeness.

If the function is continuous function and ∫0 to 8 f(u) du = 6, the value of ∫ 1 to 3 xf(x² - 1) dx is B) 3.

Given ∫0 to 8 f(u) du = 6 and we need to find the value of ∫ 1 to 3 xf(x² - 1) dx

We can say, u = x² - 1

Differentiating both sides

du = 2x dx

dx = du/2x

When x = 1,

         u = 1² - 1 = 0

and when x = 3

         u = 3² - 1 = 8

So, ∫ 1 to 3 xf(x² - 1) dx can be written as

           ∫ 1 to 3 xf(x² - 1) dx = ∫ 0 to 8 xf(u)  du/2x

                                          = 1/2∫ 0 to 8 f(u) du

It is given that ∫0 to 8 f(u) du = 6

So, ∫ 1 to 3 xf(x² - 1) dx = 1/2 x 6 = 3

The points of intersection are (-0.4, -0.2) and (2.8, 16.8). The smallest x-value is -0.4 and the largest x-value is 2.8.

To graph the curves y = x^5 and x = y(y - 1)^2, first plot the points on the graph for y = x^5. This can be done by substituting in values for x and then finding the corresponding values for y. For example, when x = -3, y = -3^5 = -243. When x = 0, y = 0^5 = 0. When x = 3, y = 3^5 = 243. After plotting the points, draw a smooth curve connecting them. Next, plot the points on the graph for x = y(y - 1)^2. This can be done by substituting in values for y and then finding the corresponding values for x. For example, when y = -2, x = -2(-2 - 1)^2 = -2(-3)^2 = 18. When y = 0, x = 0(0 - 1)^2 = 0(-1)^2 = 0. When y = 4, x = 4(4 - 1)^2 = 4(3)^2 = 36. After plotting the points, draw a smooth curve connecting them. The curves intersect at two points. The points of intersection are (-0.4, -0.2) and (2.8, 16.8). The smallest x-value is -0.4 and the largest x-value is 2.8.

The probability of an event happening is represented as a fraction, with the numerator being the number of favorable outcomes and the denominator being the total number of outcomes.

In this case, if the player throws two darts, the probability that both land in a shaded region is equal to the product of the probabilities of each dart landing in the shaded region.

If the shaded region is a circle with radius r and the darts are randomly thrown onto a larger circle with radius R, then the probability of a dart landing in the shaded region is given by:

P = (Area of shaded region) / (Area of larger circle) = (πr^2) / (πR^2)

So, the probability that both darts land in the shaded region is given by:

P = (πr^2 / πR^2) * (πr^2 / πR^2) = (πr^2 / πR^2)^2
