Answer:  $2 or $9
<u>Step-by-step explanation:</u>
Revenue (R) = $1800 , x = 1100 - 100p
R = xp
1800 = (1100 - 100p)p             <em>substituted x with 1100 - 100p</em> 
1800 = 1100p - 100p²             <em>distributed p into 1100 - 100p</em>
100p² - 1100p + 1800 = 0       <em>added 100p² & subtracted 1100p</em> on both sides
      p² - 11p + 18 = 0                <em>divided both sides by 100</em>
(p - 2) (p - 9) = 0                     <em>factored quadratic equation</em>
 p = 2  p = 9                          <em>applied Zero Product Property to solve for p</em>

Answer:
<h2>
√34sin(x + 0.33π)</h2>
Step-by-step explanation:
The general form of the equation acosx + bsinx = Rsin(x + e) where R is the resultant of the constants 'a' and 'b' and e is the angle between them.
R = √a²+b²

Given the function f(x) = 3 cos x + 5 sin x, comparing with the general equation;
a = 3, b = 5
R = √3²+5²
R = √9+25
R =√34

in radians;
 
3 cos x + 5 sin x = √34sin(x + 0.33π)
