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.

Madie drove 200 miles at a speed of 50 miles per hour. Which equation will help you find the number of hours she was driving? St

aalyn [17]

Answer:

StartFraction 50 miles Over 1 hour EndFraction = StartFraction 200 miles Over question mark hours EndFraction

Step-by-step explanation:

For constant speed, miles and hours are proportional. One possible equation is ...

$\dfrac{50\,\text{miles}}{1\,\text{hour}}=\dfrac{200\,\text{miles}}{?\,\text{hours}}\qquad\text{matches the first choice}$

_____

Comment on the solution

I personally like to put the unknown in the numerator, so the equation can be solved in one step. The equation above requires two steps: one to cross-multiply, and one to divide by 50.

I might write the equation as ...

(? hours)/(200 mi) = (1 hour)/(50 mi) . . . . multiply by 200 mi to solve

Another way to write the equation is matching the ratios of times to corresponding miles:

(? hours)/(1 hour) = (200 mi)/(50 mi)

This only requires simplification to solve it: ? = 4.

If P(A) = 0.25, then the probability of the complement of A is

djverab [1.8K]

Answer:

P(A') = 0.75

Step-by-step explanation:

We are given that the probability P(A) = 0.25 and we are to determine the probability of the complement of A.

According to the Complement Rule of any probability, the sum of the probabilities of an event and its complement must be equal to 1.

So for for the event A,

P(A) + P(A') = 1

0.25 + P(A') = 1

P(A') = 1 - 0.25

P(A') = 0.75
