Answer: f(1)=2, f(n)= f(n-1) +1 for n>1
Step-by-step explanation:
It’s all one answer
Answer: -8^4
Step-by-step explanation:
The answer is infinitely many solutions.
<span>x - y = 11
-x + y = -11
_____
Express the first equation in the term of x and substitute it into the second equation:
x = y + 11
</span>-x + y = -11
_______
-(y + 11) + y = -11
-y - 11 + y = -11
-y + y = 11 - 11
0 = 0
So, the system has infinitely many solutions.
The tangent trigonometric function is equal to the quotient of sine and cosine through the trigonometric identity. In this case, we are given with x = 9 tan (theta). Hence the answer to this problem is the expounded algebraic expression x = 9 sin (theta) / cos (theta).
