Rewrite the function, differentiate, and then simplify<br><br> y= 3/√x

Anit [1.1K]

Answer:

$\frac{dy}{dx}$ = - $\frac{3}{2x^{\frac{3}{2} } }$

Step-by-step explanation:

Differentiate using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

Given

y = $\frac{3}{\sqrt{x} }$ = 3 $x^{-\frac{1}{2} }$ , then

$\frac{dy}{dx}$ = - $\frac{3}{2}$ $x^{-\frac{3}{2} }$ = - $\frac{3}{2x^{\frac{3}{2} } }$

Answer:

We are given that the frame is 2 units wide, which means that we subtract the length of the outer frame by 2 units for each side:

7 - 2 -2 = 3

9 - 2 -2 = 5

Now, we have the length and width for the smaller rectangle, so we use the area formula (area = length*width) to get:

3*5 = 15
