Answer:
The answer of this equation is {2,2,2,2}
Step-by-step explanation:
the number on the left is the x value which is the domain
2 and 9 are factors<span> of 18.</span>
<span>When we have two or more given numbers, we can find the largest factor that both numbers have in common. This is called the </span>GCF<span> or the </span>Greatest Common Factor.
There are several different methods that can be used to find the GCF. Let's take a look at some of the methods.
Method 1:<span> List out the factors.</span>
<span>Example: Find the GCF of 64 and 96. </span>
Step 1:<span> List the factors of each number. </span>
64: 1, 2, 4, 8, 16, 32, 64
96: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
Step 2:<span> Look for factors that both lists have in common.</span>
Step 3:<span> Pick out the largest factor that both lists have in common and call this the GCF.</span>
Therefore, the GCF of 64 and 96 is 32.
Method 2:<span> Upside Down Division</span>
Find the GCF of 280 and 144.
Step 1:<span> Place the numbers inside an upside down division bar.</span>
Step 2:Now, we need to divide both numbers by a common factor. Because both of the numbers are even, we could start with 2.The answer goes underneath the bar.
Step 3:<span> We will continue to divide until we have two numbers that are relatively prime. Remember that relatively prime means two numbers that do not have any common factors other than 1.</span>
<span>35 and 18 are relatively prime. </span>
Step 4:<span> Now we take all of the factors on the side and multiply them together.</span>
Answer:
15
Step-by-step explanation:
0 + 1 = 1
1 + 2 = 3
3 + 3 = 6
6 + 4 = 10
10 + 5 = 15
Answer:
yes
Step-by-step explanation:
I'm going to give you a slightly different answer, but it's going to make sense :-)
First, let's review what "sin" and "cos" really mean. They are functions that take as an input an angle, which we call theta. They output the base (cos) and height (sin) of a triangle which as a hypotenuse of length 1.
Now, let's pick some examples. If we happen to set theta to 45 degress, you will get a triangle that looks like this:
In this case, both sin(theta) and cos(theta) are the same number, the square root of 1/2. So cos(theta) + cos (theta) is 2 times the square tool of 1/2.
Now imagine that we now want to find cos (theta + theta). Remember that theta was 45 degrees, so this will be cos (45 + 45), or cos (90).
But remember that cos is the base of a triangle where theta is the angle with the base. Well, that's not a triangle at all, is it? It's just a vertical line. In fact, cos(90) will be zero.
I remember doing that yesterday i could get it for tmwr
