Let w won games, t tied games, s lose games
s=4w
t=w-5
s+t+w=43
4w+(w-5)+w=43
6w=48
w=7
s=4*7=21 games lost

Step-by-step explanation:
im not sure what u mean entirely
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.
Answer: Option 'B' and 'C' are correct.
Step-by-step explanation:
Since we have given that
A rocket was fired into the air.
The rocket reached a maximum height of 59 feet at point (3.5,59) as shown in the figure.
And it took the rocket 3.5 seconds to reach its maximum height.
and the rocket landed after 6.9 seconds, So option 'D' is false which states The rocket landed after 34 seconds.
The equation that represents the rocket’s height over time has two solutions is completely false as it has only one solutions.
Hence, Option 'B' and 'C' are correct.
( − 5 ) ( + 5 ) ( 2 + 2 5 )
