30.0 ounces is correct. Using any pairs of numbers in the table,plug into values for x and y and solve for k.

Use one of the ordered pairs that are given to find the value of 'k', the CONSTANT of variation. This number will not change, hence the word 'constant'.
15 = k*6; dividing both sides by 6 we get k = 2.5; The equation used for the table is y = 2.5x
You can find any value now by using this formula.
y = 2.5*12
y = 30

just olya [345]

The following expressions (1+cosβ)(1−cosβ)sinβ is equivalent to sin³β

<h3>What are Trigonometric Ratios ?</h3>

In a Right angled triangle , trigonometric ratios can be used to determine the value of angles and sides of the triangle.

The trigonometric expression given in the question is

(1+cosβ)(1−cosβ)sinβ

(a+b)(a-b) = a² - b²

( 1 - cos²β)sinβ

By the trigonometric Identity

1-cos²β = sin² β

 sin² β x sin β

sin³β

Therefore Option B is the correct answer.

Answer:

\large\boxed{4x+6y^3}

Step-by-step explanation:

2x+x+x+2y\times3y\times y\\\\=(2x+x+x)+(2y\times3y\times y)\\\\=4x+(2\times3)(y\times y\times y)\\\\=4x+6y^3

sweet-ann [11.9K]

Answer:

x=1/2

Step-by-step explanation:

Set up the equation: 2x-1=0

Add one to both sides. 2x=1

Divide two by both sides: x=1/2

Therefore, x =1/2, or .5
