You’ve learned about function notation in previous lessons, but could you use function notation to add two functions? how do you think you could simplify f(x) + g(x) if f(x) = 3x + 2 and g(x) = 4x? what about a function of a function such as f(g( how do you think f(g(x)) could be simplified? what situations can you think of where combining functions would be useful?

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
