A sequence is defined by the recursive function f(n+1)= f(n) -2. If f(1) =10. what is f(3)?

6

Step-by-step explanation:

f(n+1)=f(n)-2

n=1,f(2)=f(1)-2=10-2=8

n=2,f(3)=f(2)-2=8-2=6

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)
