take square root and subtract y2 from y1 and x2 from x1
Answer:
C
Step-by-step explanation:
We know that the value of 1 is 4,
So, there are 2 difference,
1 is 4
2 is 6
3 is 8
4 is 10
5 is 12
So, the first five terms is 4, 6 ,8 ,10, 12.
Answer:
x=11.2426
or
x=2.7574
Step-by-step explanation:
Try this solution:
D(f): √(2-x)≥0; ⇔ 2-x≥0; ⇔ x≤2 or x∈(-∞; 2].
Cos x = 1/√10
sin x = √( 1 - 1 /10 ) = √9/10 = - 3/√10 ( because x is in Q IV )
cot 2 x = cos 2 x/sin 2x = ( cos²x - sin²x)/ (2 sinx cosx ) =
= ( 1/10 - 3/10 )/(2 * (-3/√10)*1/√10)= (- 8/10 ) / (-6/10 ) = 8/6 = 4/3
