<span>Tan(2x) ‒ 1/Tan(2x) = 0 \\ clear the denominators by multiplying both sides by Tan(2x) </span>
<span>Tan²(2x) ‒ 1 = 0 as long as Tan(2x) exists and ≠ 0 </span>
<span>Tan²(2x) = 1 so Tan(2x) = -1 or Tan(2x) = 1 </span>
<span>Therefore, 2x = 45° or x = 22.5° or 2x = -45° or x = -22.5° </span>
<span>There are many other values of x that work but not between -180° and 180°. </span>
First, you must add the total of Monday amd Tuesday
4.32+6.86=11.18
Then you subtract the totals from this week and last week
11.18-7.89=3.29
3.29 rounds to 3.30 aka 3.3 so your answer is C
Hello!
To find what percent of states begin w/ a W, all you need to do is divide 44 by 50
44/50
Once you've done so, you'll get 0.88, which you can convert to 88%
I hope this helps!
Answer:
A,C,E
Step-by-step explanation:
A statistical question has variability in the answer, so,
A=could range from any numbers providing a wide range of results
B=it's one answer (eg.5ft4) meaning a range can't be produced
C=could range from any food providing a wide range of results
D=One answer so no variations possible
E= could be a range of numbers
therefore the slope of the line is
