[tex]\alpha^3-\beta^3 = \frac{28}{3}\sqrt{\frac{5}{3}}[/tex]
Step-by-step explanation:
Given quadratic equation is: [tex]3x^2 +6x-2=0[/tex]Comparing it with [tex]ax^2+bx+c=0[/tex], we find:[tex]a = 3,\: b= 6,\: c = -2[/tex]It is given that: [tex] \alpha\: and \: \beta[/tex] are roots of the given quadratic equation. So, we find the sum and the products of the roots.[tex] \implies \alpha + \beta =-\frac{b}{a}=-\frac{6}{3}=-2[/tex][tex] \& \:\alpha.\beta =\frac{c}{a}=-\frac{2}{3}[/tex]Since, one of the factors of [tex] \alpha^3-\beta^3[/tex] is [tex](\alpha - \beta)[/tex] . Therefore, now we will find the value of [tex](\alpha - \beta),[/tex] which can be obtained by the following formula.[tex]\alpha-\beta=\sqrt{(\alpha+\beta)^2-4\alpha\beta}[/tex][tex]\implies \alpha-\beta=\sqrt{(-2)^2-4\bigg(-\frac{2}{3}\bigg)}[/tex][tex]\implies \alpha-\beta=\sqrt{4+\frac{8}{3}}[/tex][tex]\implies \alpha-\beta=\sqrt{\frac{12+8}{3}}[/tex][tex]\implies \alpha-\beta=\sqrt{\frac{20}{3}}[/tex][tex]\implies \alpha-\beta=2\sqrt{\frac{5}{3}}[/tex][tex]\alpha^3-\beta^3 =(\alpha-\beta)^3+3\alpha\beta(\alpha-\beta)[/tex][tex] \implies \alpha^3-\beta^3 =\bigg(2\sqrt{\frac{5}{3}}\bigg)^3+3\bigg(-\frac{2}{3}\bigg)\bigg(2\sqrt{\frac{5}{3}}\bigg)[/tex][tex] \implies \alpha^3-\beta^3 =8\bigg(\sqrt{\frac{5}{3}}\bigg)^3-\bigg(\frac{6}{3}\bigg)\bigg(2\sqrt{\frac{5}{3}}\bigg)[/tex][tex] \implies \alpha^3-\beta^3 =8\times \frac{5}{3}\bigg(\sqrt{\frac{5}{3}}\bigg)-4\bigg(\sqrt{\frac{5}{3}}\bigg)[/tex][tex] \implies \alpha^3-\beta^3 = \frac{40}{3}\bigg(\sqrt{\frac{5}{3}}\bigg)-4\bigg(\sqrt{\frac{5}{3}}\bigg)[/tex][tex] \implies \alpha^3-\beta^3 = \bigg(\frac{40}{3}-4\bigg)\bigg(\sqrt{\frac{5}{3}}\bigg)[/tex][tex] \implies \alpha^3-\beta^3 = \bigg(\frac{40-12}{3}\bigg)\bigg(\sqrt{\frac{5}{3}}\bigg)[/tex][tex] \implies \alpha^3-\beta^3 = \frac{28}{3}\sqrt{\frac{5}{3}}[/tex]The value of a³-B³ from the given quadratic equation is 12.05.
What are roots of a quadratic equation?The roots to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.
Given that, a and B are the roots of the equation 3x²+6x-2=0
By comparing 3x²+6x-2=0 with ax²+bx+c=0, we get a=3, b=6 and c=-2
The roots of a quadratic equation ax² + bx + c = 0 are given by x = [-b ± √(b² - 4ac)]/2a.
Now, substitute a=3, b=6 and c=-2 in quadratic formula
That is, x = [-6 ±√(6² - 4×3×(-2))]/2×3
= [-6 ±√60]/6
= (-6±2√15)/6
= (-3±√15)/3
So, a=(-3+√15)/3 and B=(-3-√15)/3
Now, a³-B³ = [(-3+√15)/3]³- [(-3-√15)/3]³
= 12.05
Therefore, the value of a³-B³ from the given quadratic equation is 12.05.

A shoe box has a volume of 64 cubic inches and a surface area of 160 square inches. What is the surface area of a similar shoe box if its volume is only 27 cubic inches? Show your work or explain how you got your answer.
Answers
Answer:
SA = 90 in²
Step-by-step explanation:
given 2 similar shapes with sides in ratio a : b , then
ratio of areas = a² : b²
ratio of volumes = a³ : b³
Given ratio of volumes = 64 : 27 , then
ratio of sides = [tex]\sqrt[3]{64}[/tex] : [tex]\sqrt[3]{27}[/tex] = 4 : 3
then ratio of areas = 4² : 3² = 16 : 9
let x be the surface area of the smaller box then by proportion
[tex]\frac{x}{9}[/tex] = [tex]\frac{160}{16}[/tex] = 10 ( multiply both sides by 9 )
x = 90
surface area of smaller box is 90 in²
67.5 square inches is the surface area of a similar shoe box if its volume is only 27 cubic inches
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that shoe box has a volume of 64 cubic inches and a surface area of 160 square inches.
We have to find the surface area of a similar shoe box if its volume is only 27 cubic inches
Lets form a proportional equation
64/160 = 27/x
Apply cross multiplication
64x=160(27)
64x=4320
Divide both sides by 64
x=4320/64
x=67.5
Hence, 67.5 square inches is the surface area of a similar shoe box if its volume is only 27 cubic inches

HELP ME PLEASE!!!!!!
Answers
Answer:
94 square inches.
Step-by-step explanation:
Surface area is the area around a surface. Thus, in order to calculate the surface area of a rectangular prism, we just need to add up the different faces of it.
There are 2 5x4 faces, 2 3x5 faces, and 2 4x3 faces.
Thus, we get 2*20 + 2*15 + 2*12 = 40 + 30 + 24 = 94 square inches.
First you have to find area of all the sides of the shape.
You so this by multiplying 4*5=20, 3*4=12, and 3*5=15
Then double all the products because there are two of each one of the sides on the shape because it is a rectangular prism.
You get 40, 24, and 30.
Finally add all of those numbers together to get the surface area. 40+24+30=94.
94 is the surface area

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.
Here, Principal = $ 310
Rate of interest = 8%
Time = 8 years
We know,
Amount = P (1 + i )ⁿ
