so... notice the picture below, the angle in the fourth quadrant
now... notice, the cosine is just the distance the angle makes with the x-axis
so... using the pythagorean theorem, get the opposite side, from that triangle, keeping in mind that, "y" is negative in the 4th quadrant
once you get "y", get any other trigonometry value you need :)
A function is a expression that defines a relationship between one variable and another variable
Answer:
x: numbers of hot chocolate selling
y: numbers of apple cide selling
1x + 2y ≥ 240
2y ≥ 240 - x
y ≥ 120 - 0.5*x
Fx=8(20) -10
fx= 160-10
answer= 150
