Find an equation of the plane tangent to the following surface at the given point. 8 xy plus 5 yz plus xzminus56equals0; (2 com

Nimfa-mama [501]

The Question is :

Find an equation of the plane tangent to the following surface at the given point.

8xy + 5yz + xz - 56 = 0; (2, 2, 2 )

The equation of the tangent plane at (2, 2, 2 ) is 0.

Answer:

The equation of the plane tangent to the surface

8xy + 5yz + xz - 56 = 0

at the point (2, 2, 2 )

is 9x + 13y + 6z - 56 = 0

Step-by-step explanation:

Given the equation

8xy + 5yz + xz - 56 = 0

and the point

(2, 2, 2 ).

To find the equation of the plane tangent to the surface, we first differentiate the given function with respect to x, y and z respectively.

F_x = 8y + z

F_y = 8x + 5z

F_z = 5y + x

At the point (2, 2, 2)

F_x = 18

F_y = 26

F_z = 12

The equation of the plane is given as

(F_x)(x - 2) + (F_y)(y - 2) + (F_z)(z - 2) = 0

18(x - 2) + 26(y - 2) + 12(z - 2) = 0

18x + 26y + 12z - 36 - 52 - 24 = 0

18x + 26y + 12z - 112 = 0

Divide through with 2

9x + 13y + 6z - 56 = 0

This is the equation we are looking for.

The volume of Saturn is about 8.27 x 10 cubic kilometers. The volume of Earth is about 1.09 x 102 cubic kilometers. The number o

ivann1987 [24]

Answer:

Option D: $7.59*10^{2}$

Step-by-step explanation:

we know that

The volume of Saturn is about $8.27*10^{14}\ km^{3}$

The volume of Earth is about $1.09*10^{12}\ km^{3}$

Dividing Saturn's volume by Earth's volume

$\frac{8.27*10^{14}}{1.09*10^{12}} =(\frac{8.27}{1.09})*10^{14-12} =7.59*10^{2}$

Solve the equation 2p/3-12=-2

-BARSIC- [3]

Hey there!

$\frac{2p}{3} - 12 = -2$

Firstly, we are going add $12$ on each of the sides that we're working with. like ↓

$p - 12 + 12 \\ \\ = -2 + 12$

This gives us $\frac{2}{3}p = 10$ (if you are wondering how we got the out come of $10$ it is because I added $-2 + 12 = 10$

Now multiply $\frac{3}{2}$ on each of your sides

$\frac{3}{2} ( \frac{2}{3}p) \\ \\ = \frac{3}{2} (10)$

Cancel the first set and you will find the value of $p$

$p = 15$

Good luck on your assignment and enjoy your day
