Answer:
202m
Step-by-step explanation:
Complete question
(A zip line starts on a platform that is 40 meters above the ground. The anchor for the zip line is 198 horizontal meters from the base of the platform.
How long is the zip line? See attached diagram for illustration)
Using pythagoras theory
Y = 40
Z = 198
X =?
X² = y² + z²
X² = 40² + 198²
X² = 40804
X = 202m
The zip line is 202m

Answer:
Evaluating the piecewise function when X =3, we get f(3) = 7
Step-by-step explanation:
Given the following piecewise function
f(x)= { 2x+1; where x > 0
-3 when x ≤ 0
Evaluate the function when X = 3
We will evaluate f(x) =2x+1 where x > 0, because x = 3 and 3 <0
We can't use -3, because x ≤ 0, and 3 is not less than 0.
Now, evaluating the function:
So, Evaluating the piecewise function when X =3, we get f(3) = 7
