Consider the planes 4x+3y+4z=1 and 4x+4z=0. (A) Find the unique point P on the y−axis which is on both planes. ( 0 equation edit
Nana76 [90]

Answer:

Step-by-step explanation:

A) From the order of the exercise we already know that the intersection points lies on the Y-axis, so its coordinates are P(0;y;0). In order to find it, we only need to substitute the equation 4x+4z=0 into the equation 4x+3y+4z=1. Then,

1=4x+3y+4z = 3y + (4x+4z)= 3y+0.

From the expression above it is easy to obtain that y=1/3, and the intersection point is P(0;1/3;0).

B) To obtain the parallel vector to both planes we use the cross product of the normal vector of the planes.

\left[\begin{array}{ccc}i&j&k\\4&3&4\\4&0&4\end{array}\right] = 12i-0j+12k

As we want a unit vector, we must calculate the modulus of u:

|u|=\sqrt{12^2+0^2+12^2} = \sqrt{2\cdot 12^2}=12\sqrt{2}.

Thus, the wanted vector is \frac{u}{12\sqrt{2}}. Therefore,

u = \frac{1}{\sqrt{2}}i-\frac{1}{\sqrt{2}}k = \frac{\sqrt{2}}{2}i-\frac{\sqrt{2}}{2}k.

C) In order to obtain the vector equation of the intersection line of both planes, we just need to put together the above results.

r = \frac{1}{3}j +\lambda \left( \frac{\sqrt{2}}{2}i- \frac{\sqrt{2}}{2}k \right)

where \lambda is a real number.

Mr. Marks gives his students a pop quiz on graphing on the coordinate plane. Sixty percent of his students fail the quiz. What s
disa [49]

Reteach the (x,y) coordinate structure and axes to the whole class.

When the majority of the class does not understand a topic, it should be retaught in a different manner.

A coordinate plane is a dimensional plane fashioned by way of the intersection of a vertical line known as the y-axis and a horizontal line known as the x-axis. These are perpendicular traces that intersect each differently at zero, and this point is called the origin.

Here are the characteristics for each of the four coordinate plane quadrants:

  • Quadrant I: positive x and positive y.
  • Quadrant II: negative x and positive y.
  • Quadrant III: negative x and negative y.
  • Quadrant IV: positive x and negative y.

The XY Coordinate plane is fashioned while two quantity strains (called axes) meet at a 90° attitude. The horizontal line is called the x-axis and the vertical line is known as the y-axis. The point where they meet is referred to as the beginning. The axes separate the plane into four sections called quadrants.
