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 incorr
Andrei [34K]

Answer:

The equation of the plane is represented by \frac{1}{18}\cdot x + \frac{1}{18}\cdot y + \frac{1}{18}\cdot z = 1.

Step-by-step explanation:

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

(a,b, c)\,\bullet\,(x,y,z) = 1 (1)

Where:

a, b, c - Plane coeffcients.

x, y, z - Coordinates.

We need three distinct points to determine all coefficients. If we know that (x_{1},y_{1},z_{1}) = (0,9,9), (x_{2},y_{2}, z_{2}) = (9,0,9) and (x_{3},y_{3},z_{3}) = (9,9,0), the system of equations to be solved is:

9\cdot b + 9\cdot c = 1 (1)

9\cdot a + 9\cdot c = 1 (2)

9\cdot a + 9\cdot b = 1 (3)

The solution of this system is a = \frac{1}{18}, b = \frac{1}{18}, c = \frac{1}{18}.

Hence, the equation of the plane is represented by \frac{1}{18}\cdot x + \frac{1}{18}\cdot y + \frac{1}{18}\cdot z = 1.

A cylinder with a radius of 1 cm and a height of 21 cm has the same volume as a cone with a height of 7 cm. What is the radius o
Maru [420]
Volume of the cylinder = πr²h = π(1)² (21) = 21π cm³

Volume of the cone = 1/3 π r² h

21π = 1/3 π (r)² (7)

r³ = 21π ÷ (7/3 π) 

r² = 9

r = 3

Answer : Radius = 3
