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>
<em></em>
Mode: 7, Median: 7, Mean: 5.6
Median:
First, we put it in numerical order:
2, 3, 7, 7, 9
Then we crossed out the two on the sides:
3, 7, 7
Then we do it again...
7
Then we are left with 7! So the median is 7!
Mode:
Mode is most common number in the group of number so the number that appeared two times is 7. So the mode is 7.
Mean:
We add all numbers together:
2+7+3+7+9 =28
Then we divide that number by the number of numbers we have:
28/5 = 5.6.
Hope this can help you! Please put branliest answer if you like it!
Cos( 6 x ) = 1/2
6 x = 60° ⇒ x 1 = 10°
6 x = 300° ⇒ x 2 = 50°
6 x = 420° ⇒ x 3 = 70°
6 x = 660° ⇒ x 4 = 110°
x 5 = 130°, x 6 = 170°, x 7 = 190° , x 8 = 230°, x 9 = 250°,
x 10 = 290°, x 11 = 310°, x 12 = 350°
Answer: there are 12 solutions on the interval ( 0 , 2π ).
No because 75 ÷ 9 = 8.333
Ok so you spent 19 dollars the difference between prices is 5 dollars and your answer would be 12 and 7. If you need any help let me know.
