The equation of a line in Slope-Intercept form, is:
Where "m" is the slope of the line and "b" is the y-intercept.
By definition:
- The slopes of parallel lines are equal and the y-intercepts are different.
- The slopes of perpendicular lines are opposite reciprocals.
For this case you need to rewrite the equations given in the exercise in Slope-Intercept form by solving for "y".
- Line #1:
You can identify that:
- Line #2:
You can identify that:
Therefore, since:
You can conclude that: The graphs of the equation are parallel.
Answer:
all options are correct.
Step-by-step explanation:
The correct options among all the options are:
- <em>Ancient mathematicians used trigonometry to find angles of triangles.</em>
Trigonometry is used to find the size of a missing side or angle in a right- angled triangle using the sine, cosine or tangent ratios.
- <em>Ancient mathematicians used trigonometry to track the position of the sun.</em>
It is also used in oceanography in calculating the height of tides in oceans.
- <em>Tangent was the first trigonometric relationship used by mathematicians.</em>
The three main functions in trigonometry are Sine, Cosine and Tangent.The functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functions.
- <em>Cosine was the first trigonometric relationship used by mathematicians.
</em>
- <em>Sine was the first trigonometric relationship used by mathematicians.</em>
We can say that because 3 times 9, which would equal 27, could be the same as 4*9, which would be 36. So Pat needs 36 pints of green paint. Down below is a tape diagram so you can see what it is.
Its 95
Tens = 90
Ones = 5
90 + 5 = 95
