Answer:

D) 0.5x^3y + 4x^2 y^2 - 2xy^3

Step-by-step explanation:

Set up an equation to model the situation,

(-0.5xy)(x^2 + 8xy - 4y^2)

Distribute, multiply each term in the parenthesis with the term outside of the parenthesis. Don't forget the laws of exponents, when one multiplies two exponents, with the same base, then one adds the two exponents. A number with no exponential term is two the first degree meaning that it is to the power of one.

-0.5x^3 y - 4x^2 y^2 + 2xy^3

If the height of the tree trunk is 13 feet and the radius is 1.5 feet what is the volume in cubic feet round to the nearest 10th
Mumz [18]

Answer:

91.8 feet^3

Step-by-step explanation:

We can find out the area of a circle and then multiple that by the height to get the volume of the tree trunk (which is a cylinder).

Area of circle formula: pi x r^2

3.14 x 1.5^2 = 7.065

Now we can multiple it by the height and round to the nearest 10th.

7.065 x 13 = 91.845

91.845 -> 91.8

Hope this helps! Brainliest?

The answer is 25 chicks

Reasoning:

This is a simple problem.
Consider you are the only chick that matters, and construct a table to say whether YOU get pecked. Your chance of being pecked comes down to only 4 outcomes. (1) YES - pecked twice. (2) YES - pecked from left wing only. (3) YES - pecked from right wing only. (4) NO - unpecked.
The table has 4 elements, all of equal probability, 1 of which is unpecked. YOU are therefore pecked 3:1 ratio or 3:4 opportunities  75% of the time. For convenience, this needs to be conducted for 100 trials of YOU, and the answer is that 25 times YOU will NOT be pecked. The circular nature of the 100 chicks says that YOU are not unique, and your experience is the same as the others, so we extrapolate your experience of 100 trials to a single trial of 100 chicks just like YOU. 25 unpecked chicks, 50 get pecked once, 25 get double pecks.

This is the same table constructed for 100 women having two children and asking how many have no girls.

Please help!!! Brainliest for whoever is right! What is the sum of the rational expressions below?
fenix001 [56]

Answer:

<h2>\frac{5 {x}^{2} + 5x + 3 }{3 {x}^{2}  + 3x}</h2>

Step-by-step explanation:

\frac{2x + 3}{3x}  +  \frac{x}{ x + 1}

Write all the numerators above the least common denominator

\frac{(x + 1)(2x + 3) + 3 {x}^{2} }{3x(x + 1)}

Multiply the parentheses

\frac{2 {x}^{2} + 3x + 2x + 3 + 3 {x}^{2}  }{3x(x + 1)}

Distribute 3x through the parentheses

\frac{2 {x}^{2}  + 3x + 2x + 3 + 3 {x}^{2} }{3 {x}^{2}  + 3x}

Collect like terms=\frac{5 {x}^{2} + 5x + 3 }{3 {x}^{2} + 3 x}

Hope this helps...

Good luck on your assignment...
