What two positive real numbers whose product is 21 have the smallest possible sum?

GalinKa [24]

Answer:

$x=\sqrt{21}$

$y=\sqrt{21}$

Step-by-step explanation:

Let x and y are the two positive real numbers

product of two numbers is 21

$x y=21$

$y=\frac{21}{x}$

The sum of the two numbers is f(x) =x+y

Replace y with 21/x

$f(x) =x+\frac{21}{x}$

we need to find smallest possible sum , so we take derivative using power rule

$f'(x)= 1-\frac{21}{x^2}$

when sum is minimum then the derivative is equal to 0

$0= 1-\frac{21}{x^2}$

$0=\frac{x^2-21}{x^2}$

multiply both sides by x^2

$x^2-21=0$

$x^2=21$

Take square root on both sides

$x=\sqrt{21}$

$y=\frac{21}{x}$

$y=\frac{21}{\sqrt{21}}$

$y=\sqrt{21}$

Please someone help with this

Sholpan [36]

A=16 and b=63

So we have to use the Pythagoras theorem for this and that is:
a^2+ b^2 = c^2

And we want to find c , which is the long side of the triangle so..

16^2+ 63^2= 4225
So c^2 =4225

c= square root of 4225
C= 65
