Answer:
100% increase
Step-by-step explanation:
Corresponding Parts of Congruent Triangles are Congruent
meaning that the same parts of triangles that are congruent will also be congruent
Well the line is called a ray because because the left of the endpoint is a dot and it doesn't go anywhere. So your answer is a ray.
hope that helped
Answer:
(a) true
(b) true
(c) false; {y = x, t < 1; y = 2x, t ≥ 1}
(d) false; y = 200x for .005 < |x| < 1
Step-by-step explanation:
(a) "s(t) is periodic with period T" means s(t) = s(t+nT) for any integer n. Since values of n may be of the form n = 2m for any integer m, then this also means ...
s(t) = s(t +2mt) = s(t +m(2T)) . . . for any integer m
This equation matches the form of a function periodic with period 2T.

(b) A system being linear means the output for the sum of two inputs is the sum of the outputs from the separate inputs:
s(a) +s(b) = s(a+b) . . . . definition of linear function
Then if a=b, you have
2s(a) = s(2a)

(c) The output from a time-shifted input will only be the time-shifted output of the unshifted input if the system is time-invariant. The problem conditions here don't require that. A system can be "linear continuous time" and still be time-varying.
__
(d) A restriction on an input magnitude does not mean the same restriction applies to the output magnitude. The system may have gain, for example.
