Actually Welcome to the Concept of the Inverse Trigonometry Function.
So here, we get as
SinX = 1/2
X = Sin^-1(1/2)
X= 30°
Step-by-step explanation:
From kindergarten to sixth grade is seven grades and if for each grade 57 new students get enrolled then 57*7=399 there are 399 students
Answer: Friday
Step-by-step explanation:
If February 29th is on a Sunday, then, the day that the next February 29th will fall on will be Friday.
First and foremost, we should realise that February has 28 days but in leap years which takes place every 4 years, it has 29 days.
We should realise that the dates in the calendar are arranged in such a way that if a particular date falls on a particular day this year, the date will fall on the next day next year. e.g. since January 20 falls on. Wednesday this year, it will fall on a Thursday next year.
Since February 29 is a date for a leap year, following the above explanation, if February 29th is on a Sunday, then, the day that the next February 29th will fall on will be Friday which is in the next four years.
Sin(pi/6) would be appropriate as that is 1/2
Answer:
-4
Step-by-step explanation:
Rewrite 16 as 4 squared
Pull terms out from under the radical, assuming positive real numbers
-1 x 4
Then you get the answer -4
