As you can see, if you draw a segment from a to j, you'll get the right triangle JAG, with right angle in A.

AJ would be the hypothenuse.

AJ = √AG²+GJ² = √9²+12² = √81+144 = √225 = 15 units.

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.

Step-by-step explanation:

$3x \leqslant 5 \\ 3x \div 3 \leqslant 5 \div 3\\ x \leqslant \frac{5}{3}$

explanation for second step:

you divide each side by 3 to get rid of the '3' in '3x'

Rina8888 [55]

0= 0/8

1/2= 4/8

1= 8/8

5/8 is closer to 1/2.
