Answer:

a) The value of If(i)I  =  √2.

Step-by-step explanation:

Here the given function is f(x) = 1 -  x

To Find: If(i)I

First;y, let us find the value of f(i).

Substituting x  = i in f(x) , we get:

f(i)  = 1- i

Now, The modulus value of a function P = A + B is written as :

IPI = IA+BI = \sqrt{A^2 + B^2}

So, here calculating the value of If(i)I :

I1-iI   = \sqrt{(1)^2 + (-1)^2} = \sqrt{1+ (1)} = \sqrt {1+1} = \sqrt{2}\\\implies I1-iI  = \sqrt{2}

⇒ I1-1I = √2

or, If(i)I =√2

Hence, the value of If(i)I  for f(x) = 1 -x is√2.

A rectangle has a length five more than twice the width. If the perimeter is 22 units find the width and length
PtichkaEL [24]

Set the following: Length = L    Width = W

The length is twice the width:    L = 2*W     or:  W = L/2

Perimeter: P = 60ft = 2*L + 2*W

Substituting L for W in the perimeter equation gives:

P = 60ft = 2*L + 2*(L/2) = 2*L + L = 3L

L = 60ft/3 = 20ft    W=L/2=20ft/2=10ft

Verify result:  Perimeter= P = 60ft = 2L + 2W = 2*20ft +2*10ft = 40ft+20ft = 60ft

The area of the rectangular is: Area = A = Length*Width = L*W = 20ft*10ft = 200 (ft)^2

At a sale, dresses were sold for $90 each. This price was 75% of a
gulaghasi [49]

Answer:

A dress originally costs $120

Step-by-step explanation:

To find the original cost of the dress, we will follow the steps below;

let x represent the original cost of the dress

75% of x  = $90

\frac{75}{100}  ×    x   = $90

\frac{75X}{100}  =   $90

MULTIPLY both-side of the equation by 100

\frac{75X}{100} × 100 =   $90×100

At the right-hand side of the equation, 100 will cancel out 100, leaving us with just 75x

75x = $9000

DIVIDE both-side of the equation by 75

75x/75 = $9000/75

At the left-hand side of the equation 75 will cancel-out 75 leaving us with just x

x=  $9000/75

x = $120

A dress originally costs $120

Discussion:

3m * 4 * n * n  =                       => 3* 4 = 12

12 m * n * n                              => as n*n = n^2

12 m n^2
