Let f(z) = (4z ² + 2z) / (2z ² - 3z + 1).
First, carry out the division:
f(z) = 2 + (8z - 2) / (2z ² - 3z + 1)
Observe that
2z ² - 3z + 1 = (2z - 1) (z - 1)
so you can separate the rational part of f(z) into partial fractions. We have
(8z - 2) / (2z ² - 3z + 1) = a / (2z - 1) + b / (z - 1)
8z - 2 = a (z - 1) + b (2z - 1)
8z - 2 = (a + 2b) z - (a + b)
so that a + 2b = 8 and a + b = 2, yielding a = -4 and b = 6.
So we have
f(z) = 2 - 4 / (2z - 1) + 6 / (z - 1)
or
f(z) = 2 - (2/z) (1 / (1 - 1/(2z))) + (6/z) (1 / (1 - 1/z))
Recall that for |z| < 1, we have
[tex]\displaystyle\frac1{1-z}=\sum_{n=0}^\infty z^n[/tex]
Replace z with 1/z to get
[tex]\displaystyle\frac1{1-\frac1z}=\sum_{n=0}^\infty z^{-n}[/tex]
so that by substitution, we can write
[tex]\displaystyle f(z) = 2 - \frac2z \sum_{n=0}^\infty (2z)^{-n} + \frac6z \sum_{n=0}^\infty z^{-n}[/tex]
Now condense f(z) into one series:
[tex]\displaystyle f(z) = 2 - \sum_{n=0}^\infty 2^{-n+1} z^{-(n+1)} + 6 \sum_{n=0}^\infty z^{-n-1}[/tex]
[tex]\displaystyle f(z) = 2 - \sum_{n=0}^\infty \left(6+2^{-n+1}\right) z^{-(n+1)}[/tex]
[tex]\displaystyle f(z) = 2 - \sum_{n=1}^\infty \left(6+2^{-(n-1)+1}\right) z^{-n}[/tex]
[tex]\displaystyle f(z) = 2 - \sum_{n=1}^\infty \left(6+2^{2-n}\right) z^{-n}[/tex]
So, the inverse Z transform of f(z) is [tex]\boxed{6+2^{2-n}}[/tex].
what is 18x2?????????????????
Answer:
36
Explanation:
because you add 8+8=16
you add a 1 above the other i then 1x2=2+1 =3
then you put the 6 beside the 3 and get
36
Air space used to separate a water supply outlet from any potentially contaminated source is called a(n)
O back-siphoning device
O backflow
O alr gap
O closed water container
Answer:
air gap
Explanation:
It is also called air doors or fly fans. Air space used to separate a water-supply outlet from any potentially contaminated source. The air space between the floor drain and the drainpipe of a sink is an example. An air gap is the only completely reliable method for preventing backflow.
Answer:
air gap

Determine what each letter represents in the Punnett square.
Letters A and B represent the genotypes of the ______
.Letters C, D, E, and F represent the genotypes of the _______
ps theres no pic
.
Answer:
Letters A and B represent the genotypes of the Parents
Letters C, D, E, and F represent the genotypes of the Offspring.
Explanation:
The Punnet square is a square shaped figure or diagram used to anticipate the genotypes of offspring after a certain parental cross. It helps in determining the genotype as well as phenotype of the offspring if we know the genotype of parents.
A method used to control density and overcrowding by restricting setbacks, building height, or ratio of open area is known as _________ zoning.
Answer:
Bulk zoning.
Explanation:
Zoning is a method used by municipal authorities or government authorities to divide a land area into zones. It is a urban planning method. There are several types of zoning; bulk zoning being one of them.
Bulk zoning can be defined as a set of regulations used to control lot size, ratio of floor area, open space, yards, setbacks, bulding height, etc. These setbacks and restrictions, then, help authorities to determine maximun size of a building on a zoning area, and also the positioning of the building.
Therefore, bulk zoning is the correct answer.

13. This type of insulation comes in rolls and is commonly a fiberglass type
material. It is applied by hand and is stapled when installed on walls. *
A. batt insulation
B. spray foam insulation
C. cellulose insulation
D. none of the above
Answer:
i think the answer is C.
Explanation:
Answer:
Can you mix cellulose and fiberglass insulation?
No. Even if you have moisture in your attic, once all bypasses are sealed (and/or your roof repaired by a qualified contractor, if necessary) cellulose is blown directly over the existing insulation. ... Adding new cellulose insulation on top of existing fiberglass insulation is called "capping".
Explanation:
Explain how Peccerelli's team identifies the bodies they find.
Answer:
Two methods are;
DNA
Forensic anthropology
Explanation:
Forensic investigators may use DNA samples to classify suspects or evaluate parentage. A DNA profile is just like a fingerprint.
Digital forensics is a particular sub-field of forensic science that incorporates the application of archaeological skeletal research and methods to solve crime crimes.
Answer:
They identified the bodies using DNA and forensic anthropology and DNA.

Technician A says that the most effective way to diagnose wheel speed sensor circuit faults is to utilize the live data function of your scan tool. Technician B says that once you have identified the affected circuit, the next step is to test at the sensor with a graphing multi-meter or an oscilloscope. Who is correct
Answer:
Both Technicians A & B are correct
Explanation:
In diagnosing wheel systems, both steps said by technicians A & B are correct because it's the normal procedure to diagnose wheel speed sensor circuit faults.
