Equation of opened downward parabola is (x - 1) ²= - 4/5 (y - 25/4)

Parabola is a curve created by the intersection of a cone and a plane. Generally, parabola is U shaped and either open in downward or opened in upward direction.

The formula for opened downward parabola is given by (x - h) ² = - 4p (y - k)

as the parabola contains the points (0, 5) (2, 5) and (- 2, -5)

so, the equation can be (0 -h) ² = - 4p(5 - k)   [ put the value (0, 5)]

                                       h² = - 20p+4pk ..... equation 1

while putting the value (2, 5) we have the equation of parabola.

  (2 - h) ² = - 4p(5 - k)

   4 - 4h + h ² = - 20p + 4pk .... equation 2

from the equation 1 and 2, the right-hand side is similar.

hence, 4 - 4h +h² = h²

       4 = 4h

      h = 1

put h =1 in the equation 1 we get, 1 = - 20p + 4pk .... equation 3

when we put the value ( -2, -5) in the formula.

(- 2- h) ² = - 4p ( -5 -k)

( -2 -1) ² = 20p +4pk

9 = 20p +4pk ....... equation 4

from equation 4 and equation 3

we get, 9 = 20p +4pk

               1 = - 20p+ 4pk

               -      +       -

solve by addition method and we get, 8 = 40p

                                                           p = 1/5

  from h = 1 and p = 1/5 we get the value of k from equation 3

  1 = - 20/5 + 4/5k

 k = 25/4

now the equation of opened downward parabola will be.

(x - 1) ² = - 4/5 (y - 25/4)

The common denominator of y + [(y - 3)/3] in the complex fraction {y + [(y - 3)/3]}/(5/9 + 2/3y) is 5y + 6.

The Latin word "nomen," which also appears in words like "nominate" and "nomenclature," is the root of the English word "denominator," which means "name." And that's essentially what a fraction's denominator does: it "names" or denotes the kind of fraction that is specified by the numerator (the top part).

step1

{y + [(y - 3)/3]}/(5/9 + 2/3y)

multiply and divide with ‘9y'

9y/9y.{y + [(y - 3)/3]}/(5/9 + 2/3y)

9y.y + 9y.y - 3/3 / 9y(5/9) + 9y(2/3y)

9y.y + 3y(y - 3) / 9y(5/9) + 9y(2/3y)

9y.y + 3y(y - 3) / y.5 + 9y.2/3y

-74 f = -6,142 ⇒ f = -6,142 / -74 ⇒f = 83 .

One-step equations can be solved using any one of the following four methods: adding, subtracting, multiplying, or dividing. Both sides of an equation will stay equal if the same integer is added to both sides. A mathematical expression should be evaluated according to a rule known as the order of operations.

The PEMDAS acronym can help us recall the following in that order: parentheses, exponents, multiplication and division (left to right), addition and subtraction (from left to right). A balance scale is like an equation. The scale (or equation) will become out of balance if we add or subtract from one side. Mathematical equations must ALWAYS be balanced such that both sides are equal when the equation is completed.

To determine whether the sequence converges or diverges, we can use the Squeeze Theorem.

We can see that

[tex]4/(n + 5n^2) < = An < = (4 + 3n^2)/(n + 5n^2)[/tex]

As n tends to infinity, [tex]4/(n + 5n^2)[/tex]  tends to 0 and[tex](4 + 3n^2)/(n + 5n^2)[/tex]  tends to[tex]4/(5n^2)[/tex]  which also tends to 0.

So by the Squeeze Theorem, we can say that An tends to 0 as n tends to infinity. Hence the limit of the sequence is Lim n-> An = 0

We can also see that the numerator of An is a constant and the denominator is a polynomial with degree 2. Since the denominator's degree is greater than the numerator, the limit will be zero as n -> infinity.

Therefore, the sequence converges to 0.

The lowest price that would yield a profit of 35% is 1.18.

A product is sold at a profit if the price is higher than the cost price. When a product is sold for less than what it costs to produce, the seller suffers a loss.

Each bag contains 150g of sweets.

The total number of bags filled with a total of 3kg sweets can be calculated as follows:

3kg = 3000g

Number of bags = [tex]\frac{3000}{150}[/tex] = 20 bags

Profit is given by the following formula:

[tex]P= \frac{SP - CP }{CP} * 100[/tex]

The Cost price, CP = 17.60 and profit is 35%, substitute the value in the formula above:

[tex]35 = \frac{SP - 17.60}{17.60} *100\\ \\\frac{(35)(17.60)}{100} = SP - 17.60\\\\6.16 = SP -17.60\\\\6.16 + 17.60 = SP\\\\SP= 23.76[/tex]

Find the cost of each 30 bags as follows:

We calculate the percentage of black paint in each mix by dividing the amount of black paint by the total amount of paint and multiplying by 100. Julian's mix has a black paint percentage of 52.94% while Harper's mix has a black paint percentage of 58.33%. Therefore, Harper's gray paint will be darker.

The first step to determine whose gray paint will be darker is to calculate the percentage of black paint each student has in their mix. To find this, one must know that the percentage is calculated by dividing the part (the quantity of black paint) by the whole (the total amount of paint) and then multiplying by 100.

Julian's percentage of black paint: (9 cups black / 17 total cups) * 100 = 52.94%

Harper's percentage of black paint: (7 cups black / 12 total cups) * 100 = 58.33%

Since the percentage of black paint correlates with the darkness of the gray paint, Harper's gray paint will be darker because it contains a higher percentage of black paint.

What is a cubic function?

A cubic function is a function in mathematics where the variables x can take on real values and the coefficients a, b, c, and d are complex numbers. In other words, it is a real function as well as a polynomial function of degree three.

F(x) = x³ denotes the "basic" cubic function. It is depicted in the graph below. The greatest power over the x variable(s) in a cubic function is 3. The graph can be made "wider" or "skinnier" by the coefficient "a," or it can be reflected (if the value is negative): The graph's y-intercept serves as the constant "d" in the equation.

A cubic function equation is of the form f(x) = ax³ + bx² + cx + d, where a, b, c, and d are constants (or real numbers) and a ≠ 0.

The area of a (equilateral) triangle with side 8cm is 16√3cm^2.

What is a triangle and its types?

A figure which has a three-sided closed figure is called a triangle.

Types

Equilateral Triangle

A triangle where all the sides are the same is called an equilateral triangle.

Isosceles Triangle

When two of the sides of a triangle are the same it’s called an isosceles triangle. It’s a hard one to spell, but an easy one to recognize!

Scalene Triangle

In our last triangle, none of the sides have the same length, so this is called a scalene triangle.

Acute Triangle

when the largest angle in the triangle  is less than 90, that is an acute triangle. Just remember that acute angles are less than 90 degrees.

Right Triangle

When the largest angle is exactly 90 degrees. You might remember that a 90-degree angle is a right angle, so this triangle is a right triangle.

Obtuse Triangle

When largest angle is more than 90 degrees, this is an obtuse angle, so we call this triangle an obtuse triangle.

Area of an equilateral triangle whose side is 8 cm is √3/4*a^2 where

a=8

= √3/4*8^2

= √3/4*64

= √3*16
