A type of number pattern is Pascal's Triangle. The triangle-shaped arrangement of integers known as Pascal's Triangle provides the coefficients for the expansion of any binomial statement.

The arrangement of the numerals creates a triangle when they are reflected. The number 1 is first placed at the top, and then the numbers are arranged in a triangle design.

The least whole number possibility for the third side is 8 cm. The greatest whole number possibility for the third side is 22 cm.

A triangle is a three-sided polygon. It is a geometric shape that has three edges and three vertices. Triangles can be classified based on their side lengths (such as equilateral, isosceles, or scalene) or based on the angles between their sides (such as acute, right, or obtuse). Triangles are a fundamental shape in geometry and are used in many branches of mathematics and physics. To form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

Using this rule, we can find the possible range of values for the third side of the triangle.

The least possible length of the third side would be:

8.5cm + 15cm - 15cm = 8.5cm

The greatest possible length of the third side would be:

Step-by-step explanation:

Quartic Polynomial

A polynomial of degree 4.

Examples: 3x4 – 2x3 + x2 + 8, a4 + 1, and m3n + m2n2 + mn.

a quintic function is defined by a polynomial of degree five.

Because they have an odd degree, normal quintic functions appear similar to normal cubic functions when graphed, except they may possess one additional local maximum and one additional local minimum.

The quartic trinomial having a degree of 4 and the quintic polynomial having a degree of 5.

Quartic Trinomial:

A quartic trinomial is a polynomial expression of degree four that consists of three terms.

The general form of a quartic trinomial is:

[tex]ax^4 + bx^2 + c[/tex]

Example:

Let's consider the quartic trinomial:

[tex]2x^4 - 5x^2 + 3[/tex]

In this example, the term "[tex]2x^4[/tex]" is the highest degree term (degree 4), the term "-[tex]5x^2[/tex]" is the second highest degree term (degree 2), and the constant term "3" has no variable.

So, the quartic trinomial has three terms.

Quintic Polynomial:

A quintic polynomial is a polynomial expression of degree five that may contain multiple terms.

The general form of a quintic polynomial is:

[tex]ax^5 + bx^4 + cx^3 + dx^2 + ex + f[/tex]

Example:

Let's consider the quintic polynomial:

[tex]3x^5 - 2x^4 + 4x^3 + x^2 - 7x + 2[/tex]

In this example, the term "[tex]3x^5[/tex]" is the highest degree term (degree 5), the term "-[tex]2x^4[/tex]" is the second highest degree term (degree 4), and so on. The quintic polynomial has six terms, including the constant term "2".

The coordinates of A'', B'' and C'' are (-1, 4), (-4, 3) and (-1, 2) respectively.

Transformation of geometrical figures or points is the manipulation of a given figure to some other way.

Different types of transformations are Rotation, Reflection, Glide reflection, Translation and Dilation.

Given triangle has coordinates,

A(2, -2), B(5, -3) and C(2, -4).

First the triangle is translated by the rule (x, y) → (x - 1, y + 6)

A(2, -2) becomes A'(2 - 1, -2 + 6) = A'(1, 4).

B(5, -3) becomes B'(5 - 1, -3 + 6) = B'(4, 3)

C(2, -4) becomes C'(2 - 1, -4 + 6) = C'(1, 2)

Then the translated triangle is reflected across the Y axis.

When reflected a point (x, y) across the Y axis, y coordinate remains same and x coordinate flips.

A'(1, 4) becomes A''(-1, 4)

B'(4, 3) becomes B''(-4, 3)

C'(1, 2) becomes C''(-1, 2)

Hence the vertices of the triangle after undergoes translation and reflection becomes A''(-1, 4), B''(-4, 3) and C''(-1, 2).

The input variable is "Height," while the output variable is "Weight."

A variable that is independent is precisely what it sounds like. It is a stand-alone variable that is unaffected by the other variables you are attempting to assess. Age, for instance, could be an independent variable.

The cause is the independent variable. Its value is unaffected by the other study variables. Effect is the dependent variable. Changes in the independent variable affect its value.

When doing an experiment, the independent variable is what you alter, and the dependent variable is what changes as a result of that change. This is an easy way to conceive of independent and dependent variables. The independent variable can alternatively be viewed as the cause, and the dependent variable as the result.

The input and output variables are "Height" and "Weight," respectively.

Detailed explanation:

"Weight and height are related"

As we all know, the independent variable in a function of the form y=f(x) is x, and the dependent variable is y.

In other words, after substituting the values of "x," we are getting the values of the quantity "y."

The probability that on any one day, Heila will not be late for school is 0.69 or 69%.

We can use conditional probability to find the probability that Heila will not be late for school on any one day.

Let W be the event that Heila walks to school, and L be the event that Heila is late for school.

We know that:

P(W) = 0.65 (the probability that Heila walks to school)

P(L | W) = 0.4 (the probability that Heila is late for school given that he walks to school)

P(L | W') = 0.1 (the probability that Heila is late for school given that he cycles to school)

The probability that Heila is not late for school is the complement of the event that he is late for school. So:

P(L') = 1 - P(L)

We can use the formula for conditional probability to find the probability that Heila is not late for school:

P(L' | W) = 1 - P(L | W) = 1 - 0.4 = 0.6

P(L' | W') = 1 - P(L | W') = 1 - 0.1 = 0.9

We also know that the total probability of the outcomes must be equal to 1. Therefore, we can find the probability that Heila walks to school, P(W) by using the following equation:

P(W) + P(W') = 1

We know that P(W) = 0.65, so we can find P(W') by subtracting P(W) from 1:

P(W') = 1 - P(W) = 1 - 0.65 = 0.35

Now, we can use the formula of Total Probability to find the probability that Heila will not be late for school:

P(L') = P(L' | W) * P(W) + P(L' | W') * P(W')

P(L') = 0.6 * 0.65 + 0.9 * 0.35 = 0.69

Therefore, the probability that on any one day, Heila will not be late for school is 0.69 or 69%.

When the value of one item rises in relation to a fall in the other or vice versa, two values are said to be inversely proportionate. This indicates that the natural behaviour of these two quantities is contrary

In a bakery workers must make 12 batches of bagel dough an hour.

The number of batches of dough, y, that each worker needs to mix in one hour is inversely proportional to the number of workers, x.

k=12 is the constant of proportionality.

Now find the equation for inverse proportionality.

No. of workers (along x-axis) = x

No. of the bagel dough batches (along y-axis) = y

The algebraic equation relating both = x×y=k
