Answer:
=60 the second option.
Step-by-step explanation:
Given the trigonometric ratio, we can find the value of the angle by simply finding the inverse of the given ratio.
If for example Cos ∅= a, then ∅=Cos⁻¹a
If Cos (x)= 0.5, then x= Cos⁻¹ 0.5
Cos⁻1 0.5=60°
The angle whose sine is 0.5 is ∅=60°
Answer:
The period is 360° ( in radians, the period is 2π)
Step-by-step explanation:
For a sine/cosine (sinusoidal) function in the form
y = ASin(Bx-C) + D, we can say
A is the amplitude
360/B is the period
C is the phase shift
D is the vertical translation
<em>The function given is y = 2Sinx</em>
To find the period, we need 360/B. Since "B" is just "1", the period is
360/1 = 360
60% is answer...20% is taken each year so After 2 yrs it's 40% less 100-40 is 60
Answer:
Step-by-step explanation:
3/4 + (1/4 - 1/6)
= 3/4 +1/4 - 1/6
The LCM = 12
= {(3×3) + (1×3) - (2×1)}/12
= (9+3-2)/12
= 10/12
= 5/6
