Find an equation of the plane. The plane through the points (0, 9, 9), (9, 0, 9), and (9, 9, 0) Incorrect: Your answer is incorrect.

The equation of the plane is represented by .

Step-by-step explanation:

Algebraically speaking, a plane can be represented by following vectorial product:

(1)

Where:

, , - Plane coeffcients.

, , - Coordinates.

We need three distinct points to determine all coefficients. If we know that , and , the system of equations to be solved is:

(1)

(2)

(3)

The solution of this system is , , .

Hence, the equation of the plane is represented by .

The answer is in the image 

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

The answer is in the image 

The total nom of  code that can be used is equal to 5+3 = 8

The answer is in the image 

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

The solution is in the following image
