Answer is 3, you can try it. I’m pretty sure it’s correct.
Answer:
p ≥ 2
Step-by-step explanation:
10p – 8 ≥ 12
10p ≥ 20
p ≥ 2
Answer:
well it depends if its used in a problem
Step-by-step explanation:
if its a minus it less if its a + it greater or add t up to see if its equal to or which one it is
Answer:
a) n<1 and n>5
b) 0 < n < -4
c) n > 2 and n < -2
Step-by-step explanation:
The signal is given by x[n] = 0 for n < -1 and n > 3
The problem asks us to determine the values of n for which it's guaranteed to be zero.
a) x[n-2]
We know that n -2 must be less than -1 or greater than 3.
Therefore we're going to write down our inequalities and solve for n
Therefore for n<1 and n>5 x [n-2] will be zero
b) x [n+ 3]
Similarly, n + 3 must be less than -1 or greater than 3
Therefore for n< -4 and n>0, in other words, for 0 < n < -4 x[n-2] will be zero
c)x [-n + 1]
Similarly, -n+1 must be less than -1 or greater than 3
Therefore, for n > 2 and n < -2 x[-n+1] will be zero
