Answer:
The value of f(3) is -2.
Step-by-step explanation:
This is a recursive function. So

Now, we find f(2) in function of f(1). So


Now, with f(2), we can find the value of f(3).


The value of f(3) is -2.
Answer:
70 yd.
Step-by-step explanation:
The three streets at the intersection form a right triangle.
For a right triangle, the length of the longest side (called hypothenuse) is given by Pythagorean's theorem:

where
x is the length of the 1st side
y is the length of the 2nd side
h is the length of the hypothenuse
Here we want to find the hypothenuse.
We have:
x = 42 yd (length of the 1st side)
y = 56 yd (length of the 2nd side)
Substituting, we find h:

Answer:
-6
Step-by-step explanation:
