Can someone please help me !!

Would this be correct even though I didn’t use the chain rule to solve?

Semenov [28]

Answer:

Dy/Dx=1/√ (2x+3)

Yeah it's correct

Step-by-step explanation:

Applying differential by chain differentiation method.

The differential of y = √(2x+3) with respect to x

y = √(2x+3)

Let y = √u

Y = u^½

U = 2x +3

The formula for chain differentiation is

Dy/Dx = Dy/Du *Du/Dx

So

Dy/Dx = Dy/Du *Du/Dx

Dy/Du= 1/2u^-½

Du/Dx = 2

Dy/Dx =( 1/2u^-½)2

Dy/Dx= u^-½

Dy/Dx=1/√ u

But u = 2x+3

Dy/Dx=1/√ (2x+3)

The picture represents three steups. How can these setups be used to detrmine the strength

Rashid [163]

Step-by-step explanation:

The battery of setup 'a' is the strongest, this is indicated by the glowing of the bulb, as we can see the bulb is the brightest at the setup 'a'. Next moving on to the setup 'b', in this setup, the bulb is glowing a bit dimmer than the setup 'a', hence we can find out that setup 'b' battery strength is a little less than 'a'. Now coming to setup 'c', here we see that the bulb is not even glowing which indicates that the battery has no strength or that it has been used up.

Answer: 233.19

Step-by-step explanation:

equation to find volume: width x length x height

the left box:

(14-7) x 3.25 x 3.25= 73.9375 (round after adding)

the right box:

7 x 3.25 x 7= 159.25

73.9375 + 159.25= 233.1875

Round to nearest hundredth: 233.19

What is the difference? 3/11 -(-6/11) Express your answer in lowest terms.

olganol [36]

$\sf\dfrac{3}{11}-(-\dfrac{6}{11})$

Two negatives equals a positive:

$\sf\dfrac{3}{11}+\dfrac{6}{11}$

Add the numerators and keep the denominator:

$\sf\dfrac{9}{11}$

Work out an estimate for square root 1.13 + 2.84 x 9.33

Feliz [49]

hi there!

 $\large \rm = \color{brown} 27.6272 \: \\ \tt in \: \: alternate \: \: form \\ \\ \large \tt \color{cyan} \frac{17267}{625} , \color{red}27 \frac{392}{625}$ 

<h2 />

Step-by-step explanation:

 $\tt1.13 + 2.84 \times 9.33$ 

multiply the number

 $\tt \color{green}1.13 + 26.4972$ 

add the number

 $= \tt \color{green}27.6272 \\ \\ \tt \color{pink}or \: \: in \: \: alternate \: \: form \\ \\ \tt \color{purple} \frac{17267}{625} \tt \color{blue} \: , \: 27 \frac{392}{625}$
