the radius of a circle is 3 cm. what is the circumference of another circle whose area is 49 times that of the first circle ?​

Answer»

ANSWER:

Given the radius of circle is =3 cm

so, it area=\pi 3^{2}

               =9\picm^{2}

let the radius of NEW circle be =x cm. So ,its area = \pi x^{2}

                 and its given area is = 49*9\pi cm^{2}

              A\Q

                 \pi x^{2}=49*9\pi cm^{2}

                 x^{2}=49*9

                  x=\sqrt{49*9}

                    x = 7*3

                      x=21

      The radius of new circle is 21 cm

How to prove that a function is differentiable?​

Answer»

Answer:

example

Step-by-step explanation:

To show that f is DIFFERENTIABLE at all x∈R, we must show that f′(x) exists at all x∈R.

Recall that f is differentiable at x if limh→0f(x+H)−f(x)h exists.

So for f(x)=−5x, we examine

limh→0−5(x+h)−(−5x)h=limh→0−5hh=limh→0−5=−5

And so we see that f is differentiable at all x∈R with derivative f′(x)=−5.

We could also say that if g(x) and h(x) are differentiable, then so too is f(x)=g(x)h(x) and that f′(x)=g′(x)h(x)+g(x)h′(x). Then let g(x)=x,h(x)=−5, noting that both are differentiable with DERIVATES 1 and 0 respectively, LEADING to the same result.
