A^3+b^3+c^3-3abc solve this​

Mathematics
1 answer:
saul85 [17]3 years ago
3 0

Answer:

Step-by-step explanation:

a3+b3+c3-3abc

Hint: a3+b3 = (a+b)3 -3ab(a+b)

(a+b)3 - 3ab(a+b) +c3 - 3abc

(a+b)3 + c3 -3ab(a+b) - 3abc

(a+b+c)3 - 3(a+b)c(a+b+c) -3ab(a + b + c)

(a+b+c)3- 3(a + b + c)[(a+b)c+ab]

(a+b+c)3 - 3(a + b + c)[(a+b)c+ab]

(a+b+c)[(a+b+c)2 -3(ab + ac + bc)]

(a+b+c)[a2 +2ab + b2 +2ac + 2bc + c2 - 3ab - 3ac- 3bc]

(a + b + c)(a2 + b2 + c2 - ab - ac- bc)

Papessa [141]

Answer:

37.7 feet

Step-by-step explanation:

Given that:

Measurements of Frankie's yard = 20ft x 32ft

He wants to build a path from one corner to another.

To find:

The length of path = ?

Solution:

Let us consider a rectangle ABCD as shown in the attached image in the answer area.

We are given the two adjacent sides of a rectangle and we have to find diagonal of the rectangle.

To find the diagonal, we can use the Pythagorean Theorem.

We are given the base and perpendicular of the right angled triangle and we have to find the hypotenuse.

According to Pythagorean theorem:

\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}

Diagonal = 20^2 + 32^2\\\Rightarrow Diagonal = 400 + 1024\\\Rightarrow Diagonal = \bold{37.7\ ft}

9966 [12]
For the first question, the answer would be clustering. It is when the data points are close to each other. The answer, for the second question, would be positive. As the height increases, correspondingly, the weight increases as well. For the third question, I think it would be linear since as time passes your salary would increase depending on a rate.

According to national data, about 15% of American college students earn a graduate degree. Using this estimate, what is the prob
Sergio [31]

Using the binomial probability relation, the probability that exactly 27 graduates earn a college degree is 0.069

<u>Using the relation</u> :

<em>P(x = x) = nCx * p^x * q^(n-x) </em>

  • Probability of success, p = 0.15
  • q = 1 - p = 1 - 0.15 = 0.85
  • Number of trials, n = 200
  • X = 27

<u>Probability of exactly 27 graduates can be defined thus</u> :

P(x = 27) = 200C27 × 0.15^27 × 0.85^173

P(x = 27) = 0.0686264

Therefore, the probability of selecting <em>exactly 27 graduates</em> is 0.069
