The point-normal form of a plane equation: (Fx(x0, y0, z0))(x - x0) + (Fy(x0, y0, z0))(y - y0) + (Fz(x0, y0, z0))(z - z0) = 0.
To find the equation of the tangent plane to a surface at a given point, follow these steps:
Step 1: Determine the function that describes the surface in the form F(x, y, z) = 0.
Step 2: Find the partial derivative of F with respect to x, denoted as Fx.
Step 3: Find the partial derivative of F with respect to y, denoted as Fy.
Step 4: Find the partial derivative of F with respect to z, denoted as Fz.
Step 5: Evaluate Fx, Fy, and Fz at the given point (x0, y0, z0).
Step 6: Use the gradient vector, which consists of the evaluated partial derivatives (Fx(x0, y0, z0), Fy(x0, y0, z0), Fz(x0, y0, z0)), as the normal vector to the tangent plane.
Step 7: Use the point-normal form of a plane equation: (Fx(x0, y0, z0))(x - x0) + (Fy(x0, y0, z0))(y - y0) + (Fz(x0, y0, z0))(z - z0) = 0. This is the equation of the tangent plane at the given point.
By following these steps, you will find the equation of the tangent plane to the surface at the specified point.

Answer:
Multiplication identity
Step-by-step explanation:
We are given that
We have to find which property of real number is used in given expression.
Multiplication identity: It is defined as the number by which multiply any number and get itself.
Then, 1 is multiplication identity.
When we are multiplying 5 with 1 then we get 5.
Therefore, 1 is multiplication identity.
Hence, multiplication property of real numbers is used in given expression.

Question:
How long did Jenny read?
The Process:
Step-1: We need to calculate the time of texting a friend in minutes.
Recall that
We crossed out 5 and 60, i.e.,
Therefore,
Step-2: Let us calculate the remaining time.
Step-3: Jenny spends of the remaining time brushing herteeth and putting on her pajamas.
We crossed out 8 and 24, i.e.,
Step-4: Let us calculate how long Jenny read for the rest of time.
Thus, Jenny spent 15 minutes reading a book before its bedtime.
- - - - - - - - - -
Quick Steps:
Let us calculate how long Jenny read for the rest of time.
Keywords: Jenny, has an hour, before its bedtime, spends 3/5 of an hour, texting a friend, 3/8 of the remaining time, brushing her teeth, putting on her pajamas, reading her book
Answer:
The absolute function opens in downward direction.
Step-by-step explanation:
we have to find the direction in which the graph of y=-|x+2|+3 open.
The general form of an absolute value function is f(x)=a|x-h|+k.
The absolute value function will always open to the negative direction when a is negative and positive direction i.e upward when a is positive.
Here, given absolute function is y=-|x+2|+3
which gives a=-1, negative
Hence, the absolute value function will always open to the negative direction. Because this is in the form y = -|x|, it opens down.
Answer:
There is 120 milligrams of caffeine in a cup of coffee.
Step-by-step explanation:
A cup of brewed tea has 54 milligrams less caffeine than a cup of brewed coffee. A cup of tea has 66 milligrams of caffeine.
Let the amount of caffeine in a cup of coffee be = x
In the equation form, we can denote this as:
Solving for x
x = 120
Therefore, there is 120 milligrams of caffeine in a cup of coffee.
Step 2: 7x – 3x – 4 = 20
Step 3: 4x – 4 = 20Which of these is most likely the next step? (4 points)
4x = 24
4x = 16
4x = 5
4x = 80
