$\bf \cfrac{(-4x^2)(2x^{-2}y)^3}{(16x^5)(4y^3)^2}\implies \cfrac{(-4x^2)(2^3x^{-2\cdot 3}y^3)}{(16x^5)(4^2y^{3\cdot 2})}\implies \cfrac{(-4x^2)(8x^{-6}y^3)}{(16x^5)(16y^6)} \\\\\\ \cfrac{-32x^{2-6}y^3}{256x^5y^6}\implies -\cfrac{x^{-4} y^3}{8x^5y^6}\implies -\cfrac{1}{8x^5x^{4}y^6y^{-3}}\implies -\cfrac{1}{8x^{5+4}y^{6-3}} \\\\\\ -\cfrac{1}{8x^9y^3}$

George purchased a beach ball when the ball is completely filled with air it has a diameter of 12 inches which is closest to the

MArishka [77]

Answer:

The volume of George's beach ball is 904.32 cubic inches.

Step-by-step explanation:

We are given the following in the question:

Diameter of beach ball,d = 12 inches.

Radius of beach ball =

$r = \dfrac{d}{2} = \dfrac{12}{2} = 6\text{ inches}$

Volume of beach ball = Volume of sphere =

$V = \dfrac{4}{3}\pi r^3$

Putting values, we get,

$V = \dfrac{4}{3}\times 3.14\times (6)^3\\\\V = 904.32\text{ cubic inches.}$

Thus, the volume of George's beach ball is 904.32 cubic inches.

Which of the following constants can be added to x2 + 2/3 x to form a perfect square trinomial?

Nimfa-mama [501]

Answer:

Step-by-step explanation:

Next time, please be sure to share the possible answer choices. Also, please use " ^ " to indicate exponentiation: x^2 + (2/3)x.

Let's actually "complete the square" here:

Starting with x^2 + (2/3)x, identify the coefficient of the x term (it is 2/3).

Take half of that, which results in 2/6, or 1/3.

Square this result, obtaining (1/3)^2 = 1/9.

Add to, and then subtract from, this square:

x^2 + (2/3)x + 1/9 - 1/9

Rewrite x^2 + (2/3)x + 1/9 as the square of a binomial:

(x + 1/3)^2 - 1/9

In review: add 1/9 to, and then subtract 1/9 from, x^2 + (2/3)x

16y5+4y5-12y3+15y3?<br> What is the simplified form?

Eddi Din [679]

Answer:

$20y^5+3y^3$

Step-by-step explanation:

$16y^5 + 4y^5 -12y^3 + 15y^3$

All we can do here is combine like terms (add those that have the same the same exponent)

$20y^5+3y^3$

Good luck!
