I'm assuming that's a sin²(x), and not a sin(2x), right?
First, collect the terms.
7sin²(x) - 14sin(x) + 7 = 0
Factorise the quadratic.
Due to the high numbers, I'm going to use the quadratic formula to factorise the quadratic.
(-b ± √(b² - 4ac)) / 2a
Therefore
sin(x) = 1
(for both negative and positive of the quadratic formula)
Refer to the quadrant diagram.
sin(x) is a positive, meaning our answer will be on the first and second quadrant.
x = arcsin(1) = 90°
Since you don't provide an interval in your question, I'm going to assume that the interval is 0° ≤ θ ≤ 360°.
Referring again to the quadrant diagram, the solutions are going to be:
<span>θ = </span>90°, 180°
From my understanding the question is basically asking u to label each Dash/tick mark on the line. They have already given u 0 as the first one, 24 as the fifth one and 60 as the eleventh one. I’m assuming u can use any method.
Answer: use any method of division or skip counting then you will see that each line increases by 6
First line: 0
Second line: 6
Third line: 12
Fourth line: 18
Fifth line: 24
Sixth line: 30
Seventh line: 36
Eight line: 42
Ninth line: 48
Tenth line: 54
Eleventh line: 60
Don't listen to them asa is a very real thing! It's the angle side angle!! It would be C! Ssa! That doesn't exist!
Answer:
C. 2, 8, 10.
Step-by-step explanation:
For A, n = 13:
26 > 13 + 15
26 > 28 is false. Therefore A is false.
For B, n = 15:
26 > 15 + 15
26 > 30 is false. Therefore B is false.
For D, n = 11:
26 > 11 + 15
26 > 26 is false. Therefore D is false.
Therefore, C is the correct answer.
Answer:
It can't be answered because it has to have a variable or number after log200 because that's how you get 2.301.
Step-by-step explanation:
Give me the variable or number and I'll answer it from there.
