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)
Answer:
D. 172.5 inches cubed
Step-by-step explanation:
Have a good day :)
The slope is -3/2 and the y-intercept is -3. If you need me to explain I can do that :) hope this helps
All in all you would get the answer x+y=1.
