Which of the following is an acronym used in mechanical plans?

Group of answer choices

A. BTR

B. CAT

C. HVAC

D. TAN

Answer:

C. HVAC.

Explanation:

Mechanical plans can be defined as a construction document which typically comprises of drawings that illustrate, describe or show the placement, size, type and routes of various conduit and surface duct works and components.

An example of an acronym used in mechanical plans is HVAC.

HVAC is simply an acronym for heating, ventilation and air conditioning.

Basically, a HVAC system is a technology designed and developed to provide cooling and heating comfort (features) to vehicular and indoor environments such as submarines, cars, aeroplane, ships, restaurants, hotels, residential facilities or buildings etc.

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.

Answer:

Sprockets.

Explanation:

A chain drive is an efficient technique used for the transmission of mechanical power from one point to another. For example, it is used for transmitting power to the wheels of a bicycle, motorcycle, motor vehicle and other machineries such as chain saw etc.

Chain drive ratio is the ratio between the rotational speeds of the input and output sprockets of a roller chain drive system. This ultimately implies that, chain drive ratio is the ratio of the number of teeth on the driving sprocket (T1) divided to the number of teeth on the driven sprocket (T2).

Also, the chain drive ratio can be calculated by dividing the number of teeth on the large sprocket by the number of teeth on the small sprocket.

Additionally, the rotational speed of a sprocket is measured in revolutions per minute (RPM).

One of the issues with the roller chain is that, as the roller chain moves round the sprocket link by link, it affects its speed (surge) due to the change in acceleration and deceleration i.e the rise and fall of its pitch line.

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".

Answer:

Give Brainliest. Answer is C. Accrediting educational programs worldwide

Explanation:

The notes stated,

" The ABET ( Accreditation Board for Engineering and Technology ) is a non-governmental organization that accredits programs in applied science, computing, engineering, and engineering technology."

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].
