Question

If A plus B plus C equals 27 0 to the power of o end exponent comma then cos invisible function application 2 A plus cos invisible function application 2 B plus cos invisible function application 2 C plus 4 space sin invisible function application A space sin invisible function application B space sin invisible function application C equals

  1. 0    
  2. 1    
  3. 2    
  4. 3    

The correct answer is: 1


    A plus B plus C equals 27 0 to the power of o end exponent rightwards double arrow A equals B equals C equals 9 0 to the power of o end exponent comma then
    cos invisible function application 2 A plus cos invisible function application 2 B plus cos invisible function application 2 C plus 4 sin invisible function application A sin invisible function application B sin invisible function application C
    equals cos invisible function application 1 8 0 to the power of o end exponent plus cos invisible function application 1 8 0 to the power of o end exponent plus cos invisible function application 1 8 0 to the power of o end exponent plus 4 sin invisible function application 9 0 to the power of o end exponent sin invisible function application 9 0 to the power of o end exponent sin invisible function application 9 0 to the power of o end exponent
    equals negative 1 minus 1 minus 1 plus 4.1.1.1 equals negative 3 plus 4 equals 1.
