Answer:
Step-by-step explanation:
Here, given :
sin 2 x - 2 sin x = 2 .... (1)
Now, by <u>TRIGONOMETRIC IDENTITY</u>:
Sin 2Ф = 2 SinФ CosФ
⇒ sin 2 x = 2 sin x cos x
Putting back the value in (1), we get:
sin 2 x - 2 sin x = 2 ⇒ (2 sin x cos x) - 2 sin x = 2
or, 2( sin x cos x - sin x) = 2
or, sin x cos x - sin x = 1
or, (sin x) ( cosx - 1) = 1
⇒ Sin x = 1 / ( Cos x - 1)
Hence,
Answer: 220 miles
Step-by-step explanation:
(150 miles)/(7.5 inches) = 20 miles/inch
(20 miles/inch)*(11 inches) = 220 miles
Answer:
(if its a true or false question) True
Step-by-step explanation:
<u>We know-</u>
<u>Area of a circle = </u>
A=(π)r2
<u>Circumference of a circle = </u>
C=2(π)r
<u>Where pi is a constant and r is the radius of the circle.</u>
<u>Using these two formulas we can express A in terms of C as follows:</u>
<u />
c2=[2(π)r]2
⇒ c2=4[(π)2]r2 ⇒ c2=4(π)[(π)r2]
As (π)r2=A ⇒c2=4(π)A
<u>Therefore:</u>
A=c2/4(π)
Answer:
3
Step-by-step explanation:
The pattern is dividing 4 each time.
192/4=48
48/4=12
12/4=3
