Answer:
Set up an equation equal to <span>180o</span>
Explanation:
<span>3x+3x+6x=180</span>
<span>12x=180</span>
<span>x=<span>18012</span>=15</span>
So, the measure of the angles are:
<span>3x=3×15=45</span>
<span>3x=3×15=45</span>
<span>6x=6×15=<span>90</span></span>
Answer:
3n^2
Step-by-step explanation:
3, 12, 27, 48, 75
List the differences between terms:-
9, 15, 21, 27
Now find the second differences:-
6, 6, 6
The sequence in the question is quadratic and the first coefficient ( that of n^2) = 6/2 = 3. The first term in the nth term formula is 3n^2.
Now we write out the original sequence and the 3n^2 values as follows:-
3 12 27 48 75
3 12 27 48 75
They are the same so the formula for the nth term is 3n^2.
Plot the points that it has for you and then figure out how many spaces it moved that will tell you your dialation
Answer:
Step-by-step explanation:
There is a scatter plot given and we hae to find the tables.
On the x axis, day of fund drive is marked and on y axis money raised is marked.
We find out the points from the graph as Ordered pairs
(1,200) (2,300) (3,200) (4,400) and (5,300)
The above can be represented in table form as
1 2 3 4 5
200 300 200 400 300
With a scatter plot a mark, usually a dot or small circle, represents a single data point. With one mark (point) for every data point a visual distribution of the data can be seen. Depending on how tightly the points cluster together, we can find the relationship between the two variables.
