PLEASE HELPPP!!!! 13. Find the rectangular coordinates of (9, 150°). (Show work)
1 answer:
Step-by-step explanation:
Substitute in the known values of
r = 9 and θ =150 into the formulas. (9) cos (150)
y = (9) sin (150)
x = 9 (− cos (30) ) y = (9) sin (150)
The exact value of cos. (30) is <u>√3</u><u> </u>
2
x = 9 ( − <u>√3</u><u>)</u>
2
y = (9) sin (150)
blah blah blah
(9, 150) <em>is</em><em> </em>

The graph in the attached figure
Step-by-step explanation:
we have
This is a linear equation (the graph is a line)
The y-intercept is the point (0,4) ---> value of y when the value of x is equal to zero)
The x-intercept is the point (-4/3,0) ---> value of x when the value of y is equal to zero)
The slope is m=3
If the slope is changed to m=1/3
we have
This is a linear equation too (the graph is a line)
The y-intercept is the point (0,4) ---> is the same
The x-intercept is the point (-12,0) ---> the x-intercept is different
The slope is m=1/3
The second line becomes a lot less steep
Remember that the slope is the ratio between the rise and the run
In the first line the ratio rise/run is 4/1
In the second line the ratio rise/run is 1/3
