chubhunter [2.5K]

Answer:

2 chairs will be left over.

Step-by-step explanation:

Given that

There are a total of 1492 chairs.

which are to divided in 10 rows evenly.

To find:

Number of chairs left ?

Solution:

Let the number of chairs in each row = x

There are 10 rows so number of chairs in rows = 10x

Let the number of chairs left = y

Total number of chairs =10x + y  = 1492

The above equation is like:

Divisor \times Quotient + Remainder = Dividend

So, we have to find the remainder in this question where we are given Divisor and Dividend.

10 \times 149 + 2 = 1492

So, dividing 1492 with 10, we get remainder as 2.

Hence, 2 chairs will be left.

g 7. Find Re f and Im f and find their values at the given z. (Both answers should be included) f = z⁄(z + 1), z = 4 − 5
Schach [20]

Answer:

The real and imaginary parts of the result are \frac{1441}{1601} and \frac{4}{1601}, respectively.

Step-by-step explanation:

Let be f(z) = \frac{z}{z+1}, the following expression is expanded by algebraic means:

f(z) = \frac{z\cdot (z-1)}{(z+1)\cdot (z-1)}

f(z) = \frac{z^{2}-z}{z^{2}-1}

f(z) = \frac{z^{2}}{z^{2}-1}-\frac{z}{z^{2}-1}

If z = 4 - i5, then:

z^{2} = (4-i5)\cdot (4-i5)

z^{2} = 16-i20-i20-(-1)\cdot (25)

z^{2} = 41 - i40

Then, the variable is substituted in the equation and simplified:

f(z) = \frac{41-i40}{41-i39} -\frac{4-i5}{41-i39}

f(z) = \frac{37-i35}{41-i39}

f(z) = \frac{(37-i35)\cdot (41+i39)}{(41-i39)\cdot (41+i39)}

f(z) = \frac{1517-i1435+i1443+1365}{3202}

f(z) = \frac{2882+i8}{3202}

f(z) = \frac{1441}{1601} + i\frac{4}{1601}

The real and imaginary parts of the result are \frac{1441}{1601} and \frac{4}{1601}, respectively.
