Answer:

Step-by-step explanation:
The base case in the recursive function are:


The recursive case is equal to:

So replace
for
:

In the new expression
is a base case so you don't have to worry for that part, but
is still the recursive case so evaluate again in 

and
are define as base cases so you replace for it's numbers:

Now return to
and replace for the new values:

So the final answer is 20
Answer:
Fourth Quadrant
Step-by-step explanation:
The point (2, -22) is located in the 4th quadrant because the x-value is positive (to the right of the y-axis) and its y-value is negative (down from the x axis)
9+6(2^2+4)
9+6(4+4)
9+(6)(8)
9+48
=57
Answer:
x=9 x=-1
Step-by-step explanation:
2(x-4)^2=50
Divide each side by 2
2/2(x-4)^2=50/2
(x-4)^2=25
Take the square root of each side
sqrt((x-4)^2)=sqrt(25)
x-4 = ±5
x-4 =5 x-4 = -5
Add 4 to each side
x-4+4=5+4 x-4+4 = -5+4
