Would you need to use the chain rule to find the derivative of this function?

Nutka1998 [239]

Answer:

TRUE. We need to use the chain rule to find the derivative of the given function.

Step-by-step explanation:

Chain rule to find the derivative,

We have to find the derivative of F(x)

If F(x) = f[g(x)]

Then F'(x) = f'[g(x)].g'(x)

Given function is,

y = $\sqrt{2x+3}$

Here g(x) = (2x + 3)

and f[g(x)] = $\sqrt{2x+3}$

$\frac{dy}{dx}=\frac{d}{dx}(\sqrt{2x+3}).\frac{d}{dx} (2x+3)$

y' = $\frac{1}{2}(2x+3)^{(1-\frac{1}{2})}.(2)$

= $(2x+3)^{-\frac{1}{2}}$

y' = $\frac{1}{\sqrt{2x+3}}$

Therefore, it's true that we need to use the chain rule to find the derivative of the given function.

sThe number of users on a social networking site was 45 thousand in February when theyofficially went public, and grew to 60 tho

svetoff [14.1K]

Given:

No of users in February is 45,000 and in october its 60,000.

$P=45000(\frac{4}{3})^{(\frac{3}{2})^t}$

t=2

$P=45000(\frac{4}{3})^3$ $P=45000(\frac{64}{27})$ $P=5000(\frac{64}{3})$ $P=106666.6667$

Therefore, approximate no of users after 2 years is 106667.

Please help explain one and I'll figure out the rest thanks

Nookie1986 [14]

The page gives you the information that 1 kg is equal to 1000 grams.
This means that you just need to multiply each kg by 1000.

e.g. $6.8 * 1000 = 6800$

Hope this helps!
