Given:

|3+4 i|+|3-4 i|+|-3+4 i|+|-3-4 i|

Solution:

Complex formula:

|a+b i|=\sqrt{(a+b i)(a-b i)}=\sqrt{a^{2}+b^{2}}

Let us simplify one by one.

|3+4 i|=\sqrt{3^{2}+4^{2}}

           =\sqrt{25}

|3 + 4i| = 5

|3-4 i|=\sqrt{3^{2}+(-4)^{2}}

           =\sqrt{25}

|3 - 4i| = 5

|-3+4 i|=\sqrt{(-3)^{2}+4^{2}}

           =\sqrt{25}

|-3 + 4i| = 5

|-3-4 i|=\sqrt{(-3)^{2}+(-4)^{2}}

           =\sqrt{25}

|-3 - 4i| = 5

Substitute these in the given expression:

|3+4 i|+|3-4 i|+|-3+4 i|+|-3-4 i|=5+5+5+5

                                                                  =20

The solution of the expression is 20.

a subway car passes 4 stations every 10 minutes. at this rate, how many stations will it pass in 2 hours?
mars1129 [50]

The subway car passes through 48 stations in 2hours

It is given that a subway car passes 4 stations every 10 mins.

Subway car is being referred to the metro system of New York city

It is known to us that an hour has 60 mins

We are given that subway car passes 4 stations every 10 mins

Therefore number of stations passed by subway car in 1 hour

= 60/10 x 4 = 24 stations

We are required to find the number of stations crossed by subway car in 2 hours

Therefore, number of stations crossed by subway car in 2 hours= 24 x 2

= 48  stations

Therefore, the subway car passes 48 stations in 2 hours

Is -2.9 a rational or integer or whole or natural number
Burka [1]

Answer:

Step-by-step explanation:

It might help to get artsy/crafty with this.  I made it out of construction paper, but I'm going to tell you how to draw it.

Draw a large circle, over have the page.  Every number, ever, even the numbers in the smaller circles, go into this circle, fractions, decimals, negatives, zero, whole numbers, every number.   Negative infinity to positive infinity and everything in between.  These are rational numbers.

Now draw a smaller circle inside that one.  In the smaller circle there are positive and negative numbers, but no fractions.  Every number in this circle is also in the larger circle, but not every number in the bigger circle in in this smaller one.   Negative infinity to positive infinity, no fractions.   These are integers.

Draw a smaller circle inside the smaller one.  No negative numbers in this one, only positive numbers and zero.  0 to infinity, no fractions. These are whole numbers.

One more circle inside the smallest one.  Only positive whole numbers in here. No zero.   1 to infinity, no fractions.  These are natural numbers.

-2.9 is negative and decimal, so not a natural, not a whole, not an integer.  That leaves rational.
