Exactly how many planes contain points J, K, and N? 0 1 2 3
Lapatulllka [165]
Answer: 1

A plane is uniquely defined by 3 distinct points. Think of a stool with 3 legs. Each part of the leg that makes contact with the ground allows the stool to stay stable. It turns out that that extra 4th leg may make the stool wobbly which is why 3 legs are preferred.

Plz helppp: Identify the graph of the equation. What is the angle of rotation for the equation? 21x^2-8√3 xy+13y^2=225
GREYUIT [131]

Answer:

The correct option is C.

C) ellipse, -30°

Step-by-step explanation:

General form of equation for a conic section is:

(A)x² + (B)xy + (C)y² + (D)x + (E)y + F = 0

The equation of the conic section is given:

21x² - (8√3)xy + 13y² = 225

21x² - (8√3)xy + 13y² - 225 = 0

Which can be rewritten as:

(21)x² + (-8√3)xy + (13)y² + (0)x + (0)y + (-225) = 0

where

A = 21

B = -8√3

C = 13

D = 0

E = 0

F = -225

Consult the table below.

As A ≠ C and and AC > 0 , the equation represents an ellipse

The angle of rotation can be found by following equation:

cot(2θ) = (A - C)/B

cot(2θ) = (21 - 13)/(-8√3)

2θ = cot⁻¹(8/-8√3)

2θ = 120°

θ = 60° (from x-axis)

As the major axis of ellipse lies on y-axis, axis of rotation from y-axis is

θ = -30°
