Set the x value to be -2, -1, 0, 1, and 2.
If x is -2, y is -5.
2 (-2) - 1 = -5
The coordinate pair would be (-2, -5).
If x is -1, y is -3.
2 (-1) - 1 = -3
The coordinate pair would be (-1, -3).
If x is 0, y is -1.
2 (0) - 1 = -1
The coordinate pair would be (0, -1).
If x is 1, y is 1.
2 (1) - 1 = -1
The coordinate pair would be (1, 1).
If x is 2, y is 3.
2 (2) - 1 = 3
The coordinate pair would be (2, 3).
Five ordered pairs could be (-2,-5), (-1,-3), (0,-1), (1,1), and (2,3).
Triangle ABC is equilateral, because AB=BC=AC=a. Then
m∠A=m∠B=m∠C=60°.
Let point D lie on the ray BC to the right from points B and C and let CD=x. Then BD=a+x, AB=a.
Consider triangle ACD. In this triangle, m∠ACD=180°-m∠ACB=180°-60°=120°.
By the cosine theorem,
Since then
and
Therefore, you get double inequality
or
Answer:
481.5
Step-by-step explanation:
The music art museum is divided into 6 sections
Each section contains the same timert of tiles
There are 2889 tails total
Therefore the number of tiles in each section can be calculated as follows
= 2889/6
= 481.5
Hence there are 481.5 tiles in each section
Answer:
The probability of choosing bag 1 is 0,0412
Step-by-step explanation:
As the question emphasizes the probability of bag one, it is that we consider only this one. Bag 1 contains 10 blue marbles and 6 red marbles are added, in total 16 marbles. From this bag 1 extract 3 blue and 2 red marbles, without repetition. In probability it is expressed:
P (Bag₁) = 10/16 * * 9/15 * 8/14 * 6/13 * 5/12 = 0,0412
