Variable y varies directly with variable x, and y = 16 when x = 12. Enter the constant of variation in lowest terms. y = x

andrew11 [14]

k = 1.33 or 1 1/3

Formula of Direct variation. Where y is equal to the product of the constant of variation times x.

y = kx
16 = k * 12
k = 16/12
k = 1 4/12 = 1 1/3

Constant of variation is 1 1/3 or 1.33.

Question 8 of 10 What is sin 30º? 60 2 901 D A B. c.. () E. E )

levacccp [35]

Answer:

A. $\displaystyle \frac{1}{2}$

General Formulas and Concepts:

<u>Trigonometry</u>

[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] sinθ = opposite over hypotenuse

Step-by-step explanation:

<u>Step 1: Define</u>

sin 30°

<u>Step 2: Solve</u>

Since sin is opposite over hypotenuse, we need to find the length of the opposite leg of the angle and the length of the hypotenuse.

Given the triangle and it's values, the opposite leg to the 30° angle is 1 and the hypotenuse is 2.

Substituting it into sin, we have:

sin 30° = 1/2 = 0.5

∴ our answer is A.

If the sum of interior angle measures of a polygon is 720, how many sides does the polygon have?

NISA [10]

Since the interior is 720 divide it by 180 and you will get 4 so 4=n-2 where the n means number of sides. Move the 4 over to n=4+2 and you get n=6

In the hyperbola graph,how do you find the domain and range?

xxTIMURxx [149]

Step-by-step explanation:

<h2><em>y = ± 5⁄2 x</em></h2><h2><em>y = ± 5⁄2 xThe equation is the left half of the hyperbola. The domain is ( – ∞, – 1⁄5 ]. The range is ( – ∞, ∞ ). The vertical line test indicates that this is not the graph of a function.</em></h2>
