Let sin⁻¹(\frac{ \sqrt{3} }{2}) = x
Therefore, sin(x) = \frac{ \sqrt{3} }{2}
x should lie in first quadrant because √3 and 2 both are positive.

Therefore, sin(x) = 60° = π/3

I will mark BRAINLIEST and 20 points!! Please hurry!!
kkurt [141]

Answer:

Option a

Step-by-step explanation:

Given that in the first week of its release, the latest video game sold $4.5 million dollars in games.

P_t=P_0e^{-0.4t}

To find out the predicted game sales to the nearest $0.1 million for the fifth week of this game’s release we have to substitute t =5

P0 = initial sales of games = 4.5 million

Thus substitute to get

P(5) =4.5 e^{-0.4*5} =0.609 million

Hence when rounded off to 0.1 million we have

0.6 million dollars

Option a

If point C (3, 8) is reflected over the y axis what would be point C'?<br>no links please ​
olga2289 [7]

Answer:

(-3,8)

Step-by-step explanation:

When reflecting over the y-axis, you are switching from positive to negative x-values. Since 3 was already positive, we change the integer and in this case, to negative, so it becomes -3. Since the y value remains the same we don’t change the 8. So (-3,8)

I hope this helps!

Please give thanks or brainliest if this helps!
