Answer:

Answer is 6

Step-by-step explanation:

Use Trigonometry to do this equation

Sin30° = \frac{n}{12}

Multiply both sides by 12

12Sin30° = n

Then put the values into a scientific calculator

12Sin30° = n

6 = n

Answer:

n = 6\sqrt{3}

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = \frac{\sqrt{3} }{2} , then

sin30° = \frac{opposite}{hypotenuse} = \frac{n}{12} = \frac{\sqrt{3} }{2} ( cross- multiply )

2n = 12\sqrt{3} ( divide both sides by 2 )

n = 6\sqrt{3}

List all partitions of the set. (a) (1,2) (b) [a, b,c)
Alchen [17]

Answer: Hello mate!

The partition of a set is defined as a partition of the set into a nonempty subset, where the set itself is a subset of himself, then the set is a partition of himself.

a) in this we have a set of two objects; A = (1,2) the partitions of this set are: (∅), (1), (2) and (1,2). Where (∅) is the null set.

b) Now we have a set of three objects; B = (a,b,c) the partitions of this set are: (∅), (a), (b), (c), (a,b), (a,c), (b,c), (a,b,c)

What is the effect on the graph of the function f(x) = 2^x when f(x) is replaced with f(x − 3)?
mel-nik [20]

Graph of f(x-3) is compressed by a factor of  \frac{1}{8} horizontally of f(x).

<u>Step-by-step explanation:</u>

We have, the graph of f(x)= 2^{x} , on replacing f(x) by f(x-3) we get:

f(x-3)= 2^{x-3} = \frac{2^{x}}{2^{3}} = \frac{1}{8} 2^{x} = \frac{1}{8} f(x).Below shown are the images for graph of f(x) and f(x-3). Both are functions are exponential , and so having exponential graph but f(x-3) is compressed by a factor of  \frac{1}{8} horizontally . Domain and range of both functions are same i.e. F(x) & f(x-3) domain & range are same , just difference in graph : f(x-3) = \frac{1}{8} f(x).

X-y=1 this is on my homerork assignment and i want to know how to grap it
Alecsey [184]
To more easily graph this, convert it to slope-intercept form (y = mx + b, where m is the slope and b is the y-intercept):

x - y = 1
-y = -x + 1
y = x - 1

The slope is 1 and the y-intercept is -1. To graph this, plot the point (0, -1) and count 1 unit down and 1 unit to the right. Do this once more, connect the points, and you have your line.

Hope this helps.

Mr. Design is covering rectangular pieces of plywood with fabric to create a wall hanging. Each piece has an area of 12 3/4 squa
ExtremeBDS [4]

6 inches 
6 1/14 inches  
Since area is defined as length multiplied by width, this is a simple matter of division. I suspect this problem is more a matter of handling fractions, so to make things easier, convert the fractions to improper fractions in order to do the math, then convert to proper fractions after you've gotten the result. Since the area of each rectangle is 12 3/4, multiply 12 by 4 and then add 3 to get 51/4 as the area. Doing the same for the values 2 1/8 and 2 1/10 gives sizes of 17/8 and 21/10 for the widths respectively. So 
 51/4 / 17/8 = 51/4 * 8/17 = 408/68 = 6/1 = 6 
 51/4 / 21/10 = 51/4 * 10/21 = 510/84 = 85/14 = 6 1/14
