Answer:
Let the smaller integer be x and greater integer be (x+1)
x+(x+1)=91
2x+1=91
2x=91-1=90
x=90/2
x=45

Answer:
   d.  None of the above.
Step-by-step explanation:
The period is the change in x required to make a change of 2π in the argument to the sine function:
   2x = 2π
   x = π
The frequency is the reciprocal of the period, so is 1/π. There are no matching answer choices.
