5^2 = 25
6^2 = 36
33 is between 25 and 36 so the answer would be:
5< square root 33 < 6
Answer:
1. y > −2 AND y < 2
Step-by-step explanation:
6 − 5y > −4 AND 7y + 20 > 6
-6 - 6 - 20 - 20
_________ _________
−5y > −10 AND 7y > −14
y < 2 AND y > −2

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
2/3+2/3=1and 1/3
then you add 266 and 66 which is 332 and after that you add the 1 and 1/3.
that means that the answer is 333 and 1/3.
