What is the factorization of 729^15+1000?
igomit [66]

Answer:

The factorization of 729x^{15} +1000 is (9x^{5} +10)(81x^{10} -90x^{5} +100)

Step-by-step explanation:

This is a case of factorization by <em>sum and difference of cubes</em>, this type of factorization applies only in binomials of the form (a^{3} +b^{3} ) or (a^{3} -b^{3}). It is easy to recognize because the coefficients of the terms are <u><em>perfect cube numbers</em></u> (which means numbers that have exact cubic root, such as 1, 8, 27, 64, 125, 216, 343, 512, 729, 1000, etc.) and the exponents of the letters a and b are multiples of three (such as 3, 6, 9, 12, 15, 18, etc.).

Let's solve the factorization of 729x^{15} +1000 by using the <em>sum and difference of cubes </em>factorization.

1.) We calculate the cubic root of each term in the equation 729x^{15} +1000, and the exponent of the letter x is divided by 3.

\sqrt[3]{729x^{15}} =9x^{5}

1000=10^{3} then \sqrt[3]{10^{3}} =10

So, we got that

729x^{15} +1000=(9x^{5})^{3} + (10)^{3} which has the form of (a^{3} +b^{3} ) which means is a <em>sum of cubes.</em>

<em>Sum of cubes</em>

(a^{3} +b^{3} )=(a+b)(a^{2} -ab+b^{2})

with a= 9x^{5} y b=10

2.) Solving the sum of cubes.

(9x^{5})^{3} + (10)^{3}=(9x^{5} +10)((9x^{5})^{2}-(9x^{5})(10)+10^{2} )

(9x^{5})^{3} + (10)^{3}=(9x^{5} +10)(81x^{10}-90x^{5}+100)

Can someone help me answer this please
Citrus2011 [14]

Answer:

N = 3/8

Step-by-step explanation:

let the number be N

let's express the word sentence as a mathematical expression:

"a number multiplied by 2/5"

= "N" multiplied by 2/5

= N x (2/5)

= (2N/5) ------- (1)

"a number multiplied by 2/5 is 3/20" can be written as:

(2N/5)    =  3/20  (multiplying both sides by 5)

2N = (3/20) x 5

2N = 3/4      (divide both sides by 2)

N = (3/4) ÷ 2

N = (3/4) x (1/2)

N = 3/8

Number of remaining rose cards = 6
number of remaining cards = 8
P(rose card) = 6/8

P(blue marble) = 18/50
P(tail) = 30/50
P(blue marble and tail) = 18/50 x 30/50 = 540/2500

If f(x) = -3x - 5 and g(x)= 4x - 2, find (f-g) (x).
Eddi Din [679]

Answer:

-7x-3

Step-by-step explanation:

(f-g)(x) just means f(x)-g(x).

So

-3x-5-(4x-2)\\-3x-5-4x+2\\-7x-3
