Answer:
f(x+2) = sin 13.537 = 0.23
Step-by-step explanation:
f(x) = sin x = 0.2,
We want to find f(x+2)
Sinx = 0.2
x is an angle and it is expressed in degrees
In order to look for the value of the angle, x degrees, it involves a reversal process. We would find the sine inverse of 0.2
Sine inverse of 0.2 is represented as
Sin^-1 (0.2). This can be found in a calculator or you can look up the value in a trigonometry table. Looking for it in either ways,
Sin^-1 (0.2) = 11.537
Approximately 12.
To look for f(x+2), we will substitute the value of x into f(x+2)
Therefore,
= f(x+2) = f(11.537 +2) = f(13.537)
f(13.537) = sin 13.537
= 0.23407324
Approximately 0.23
x = 95°
The angles are vertically opposite so they are equal.
The answer is -2 4/5. This is in simplest form because my calculator does everything into simplest form.
Answer:
84cm^2
Step-By-Step Explanation:
Two triangles' area: 4×3÷2x2 = 12cm^2
The widest rectangle's area: 5×6 = 30cm^2
The rectangle facing the left's area: 4×6 = 24cm^2
The rectangle facing the ground's area: 3×6 = 18cm^2
Total Surface Area: 12+30+24+18 = 84cm^2

Answer:
The number of remaining fans:
Step-by-step explanation:
Number of fans when it stars raining = 62,415
Number of fans left the concert before its ending = 1,988
Number of fans when the concert end = x
62,415 = x + 1,988
x = 62,415 - 1,988 = 60,427
x = 60,427
