Differentiate x2/3 - y2/3 = 6 with respect to x and evaluate the derivative at (8, 1).

Implicit Differentiation

Step-by-step explanation:

Given:

$x^{\frac{2}{3}} -y^{\frac{2}{3}} = 6\\$

Recall:

$x^{\frac{2}{3}} -y^{\frac{2}{3}} = 6 \\ \frac{\text{d}}{\text{d}x}(x^{\frac{2}{3}} -y^{\frac{2}{3}}) = \frac{\text{d}}{\text{d}x}(6) \\ \frac{\text{d}}{\text{d}x}(x^{\frac{2}{3}}) -\frac{\text{d}}{\text{d}x}(y^{\frac{2}{3}}) = 0 \\ \frac{2}{3}x^{\frac{2}{3} -1} -\frac{2}{3}y^{\frac{2}{3} -1}\cdot \frac{\text{d}y}{\text{d}x} = 0 \\ \frac{2}{3}x^{-\frac{1}{3}} - \frac{2}{3}y^{-\frac{1}{3}} \cdot \frac{\text{d}y}{\text{d}x} = 0 \\ \frac{2}{3\sqrt[3]{x}} -\frac{2}{3\sqrt[3]{y}}\cdot \frac{\text{d}y}{\text{d}x} = 0 \\ -\frac{2}{3\sqrt[3]{y}}\cdot \frac{\text{d}y}{\text{d}x} = -\frac{2}{3\sqrt[3]{x}} \\ -2 \cdot \frac{\text{d}y}{\text{d}x} = -\frac{6\sqrt[3]{y}}{3\sqrt[3]{x}} \\ \frac{\text{d}y}{\text{d}x} = -\frac{6\sqrt[3]{y}}{-6\sqrt[3]{x}} \\ \frac{\text{d}y}{\text{d}x} = \frac{\sqrt[3]{y}}{\sqrt[3]{x}}$

the diameter of a pearl is about 4×10-¹⁴ cm and the diameter of an atom is about 10-¹¹ m. how much larger than an atom is a pear

serious [3.7K]

Answer:

The diameter of an atom is 25000 times the diameter of a pearl.

Step-by-step explanation:

Given that,

The diameter of a pearl is $4\times 10^{-14}\ cm$

The diameter of an atom is $10^{-11}\ m=10^{-9}\ m$

Taking the ratio,

$\dfrac{\text{diameter of an atom}}{\text{diameter of a pearl}}=\dfrac{10^{-9}\ m}{4\times 10^{-14}\ m}\\\\=25000$

So, the diameter of an atom is 25000 times the diameter of a pearl.

What is the solution set of 4x = y and 2x2 − y = 0

sweet-ann [11.9K]

4x=y
2x^2 -y =0 so than we substitute the y value from the first equation inside second equation in place of y we get

2x^2 -4x =0 than we solve it for x we get

2x^2 -4x =0
2x(x-2) =0

2x =0

x_1 = 0

x - 2 =0

x_2 = 2

so for x_1 = 0 result y_1 = 4*0 = 0 so the solution set will be (0,0)
and in case of x_2 = 2 result y_2 = 4*2 = 8 so the sol. set will be (2,8)

hope this will help you
