Por determinante:
5...1...1
1...0...1 = 0 --> se o determinante for igual a 0, os pontos estarão alinhados.
3...3...1
calculando: (5 x 0 x 1 + 1 x 1 x 3 + 1 x 3 x 1) - (1 x 0 x 3 + 1 x 1 x 1 + 3 x 1 x 5) =
0 + 3 + 3 - 0 - 1 - 15 =
6 - 1 - 15 =
5 - 15 = - 10 --> como não deu zero, os pontos não estão alinhados.
Firstly, we can look at our givens,
a = 17
b = 22
c = 30
And we are looking for m∠A
Is the Law of Cosines. Now we can solve for our unknown, m∠A. This will give us

Now we can substitute in our given variables.

Then we can plug this into our calculator which will give us
34.19185257 degrees
Now we just have to round to the nearest tenth
This means that the answer is 34.2 degrees
Answer:
She would most likely want C, a bar graph, or none of these.
Step-by-step explanation:
A. Frequency tables are created by arranging collected data values and their corresponding frequencies. The purpose of constructing this table is to show the number of times a value occurs. She most likely wouldn't want this to know the exact number of votes she got.
B. Pictographs are a way of showing data using images. Each image stands for a certain number of things. In this case, what use would images be when knowing the exact number of votes she got?
C. Bar graphs make it easy to compare sets of data between different groups at a glance. The graph represents categories on one axis and a discrete value in the other. The goal is to show the relationship between the two axes. Bar charts can also show big changes in data over time. When you vote, you can usually say yes or no. She can see how many people voted for her and how many people said no.
D. Then again, you can also say none of these, because these options can also show information that isn't relevant.
Hope this helped, some information may not be accurate!

Answer:
3.14 cm squared
Step-by-step explanation:
First, identify the formula necessary to calculate the area of the circle.
Area of a circle = pi x r^2
Remember, the radius is just half of the diameter! Then to square a number, is to multiply it by itself once.
pi x 1^2 =?
pi x 1
Pi
The circumference of your circle is approximately 3.14 cm squared.
