Answer:

a. Datums can be established through trigonometric leveling.

d. Geoid models have improved through time.

e. NGVD29 was matched to more tidal stations than NAVD88

Explanation:

a. Datums can be established leveling with trigonometric form, is a method to determinate different elevations.

d. Geoid models have been improved through time in the gravimetric geoid model and increase accuracy, actually, these models keep refining, there were errors ins this models, nowadays are more accurate.

e. NGVD29 was matched by tidal stations more than NAVD88.

NGVD29 was established by 26 tidal gauges in United Stated and Canada, maps were prepared, but NGVD29 was replaced because is less accurate than NAVD88.

NAVD88 were not used Additional tidal.

False sentence

b. The average sea level doesn't correspond to our current vertical data, this depends on our location.

For example

Rinconada in Peru is the highest human establishment in the world to 5100 m.

Everest is the highest summit in the world to 8848 m.

This marker indicating the sea level is located in Jerusalem.

c. Often is used levels, but there are other methods like set-up, bench mark.

f. the Dynamic heights are not the same as orthometric heights, because the dynamic heights are perfect, but the orthometric heights can change slightly, in a few words are imperfect heights.

Drupady [299]

Answer:

Hi, for this exercise we have two laws to bear in mind:

Morgan's laws

NOT(А).NOT(В) = NOT(A) + NOT (B)

NOT(A) + NOT (B) = NOT(А).NOT(В)

And the table of the Nand

INPUT OUTPUT

A B A NAND B

0 0         1

0 1         1

1 0         1

1 1         0

Let's start!

a.

Input            OUTPUT

A       A     A NAND A

1         1             0

0        0            1

b.

Input            OUTPUT

A       B     (A NAND B ) NAND (A NAND B )

0         0            0

0         1            0

1          0             0

1          1             1

C.

Input            OUTPUT

A       B     (A NAND A ) NAND (B NAND B )

0        0           0

0        1             1

1         0            1

1          1            1

Explanation:

In the first one, we only need one input in this case A and comparing with the truth table we have the not gate

In the second case, we have to negate the AND an as we know how to build a not, we only have to make a nand in the two inputs (A, B) and the make another nand with that output.

In the third case we have that the OR is A + B and we know in base of the morgan's law that:

A + B = NOT(NOT(А).NOT(В))

So, we have to negate the two inputs and after make nand with the two inputs negated.

I hope it's help you.

Implement a recursive method named power that takes 2 integer parameters named base and expo. The method will return the base ra
nika2105 [10]

Answer:

def power(base, expo):

   if expo == 0:

       return 1

   else:

       return base * power(base, expo-1)

Explanation:

*The code is in Python.

Create a method called power that takes base and expo as parameters

Check if the expo is equal to 0. If it is return 1 (This is our base case for the method, where it stops. This way our method will call itself "expo" times). If expo is not 0, return base * power(base, expo-1). (Call the method itself, decrease the expo by 1 in each call and multiply the base)
