Well, I don't what your question is, but I will assume that you want the dimensions of the rectangle after its dilation. So, multiply the dimensions of the rectangle by 2 to make it dilated.

Find a number in the closed interval [1/2,3/2] such that the sum of the number and its reciprocal is
sattari [20]

Let's assume that number as x

so,

the sum of the number and its reciprocal is

S(x)=x+\frac{1}{x}

Firstly, we will find derivative

S'(x)=1-\frac{1}{x^2}

now, we can set it to 0

and then we can solve for x

S'(x)=1-\frac{1}{x^2}=0

x=-1,x=1

Since, only x=1 lies on [1/2,3/2]

so, we will consider only x=1

now, we can plug end values and x=1 into S

At x=1/2:

we can plug x=1/2

S(\frac{1}{2})=\frac{1}{2} +\frac{1}{\frac{1}{2}}

S(\frac{1}{2})=\frac{1}{2} +2

S(\frac{1}{2})=\frac{5}{2}

At x=1:

we can plug x=1

S(1)=1 +\frac{1}{1}

S(1)=1 +1

S(1)=2

At x=3/2:

we can plug x=3/2

S(\frac{3}{2})=\frac{3}{2} +\frac{1}{\frac{3}{2}}

S(\frac{3}{2})=\frac{3}{2} +\frac{2}{3}

S(\frac{3}{2})=\frac{13}{6}

(a)

Smallest value:

The smallest value among them

S(1)=2

So, a number is 1..........Answer

(b)

Largest value:

The largest value among them

S(\frac{1}{2})=\frac{5}{2}

So, a number is \frac{1}{2}........Answer
