Question
Consider the following equation of a quadric surface:

\[
\frac{x^2}{100} + \frac{y^2}{25} = z^2
\]

**a. Find the intercepts with the three coordinate axes, if they exist.**

- **x-intercepts:**
  - A. The surface intersects the x-axis at \( x = 0 \). 
  - B. There are no x-intercepts.

- **y-intercepts:**
  - A. The surface intersects the y-axis at \( y = 0 \).
  - B. There are no y-intercepts.

- **z-intercepts:**
  - A. The surface intersects the z-axis at \( z = 0 \).
  - B. There are no z-intercepts.

**b. Find the equations of the xy-, xz-, and yz-traces, if they exist.**

- **xy-trace:**
  - A. The trace is not a single point. The equation of the xy-trace is [blank].
  - B. The trace is the single point \( (0, 0, 0) \).
  - C. There is no xy-trace.

- **xz-trace:**
  - A. The trace is not a single point. The equation of the xz-trace is [blank].
  - B. The trace is the single point \( (0, 0, 0) \).
  - C. There is no xz-trace.

There is no information provided for the yz-trace.

**c. Identify and sketch a graph of the surface.**

The problem does not provide a sketch; however, based on the equation, the surface is indicative of an elliptic cone centered at the origin.

This representation helps in understanding the geometrical shape and characteristics of the surface in a 3D coordinate system.

Expert Solution
Step 1: Solution 01

The given quadratic surface is x squared over 100 plus y squared over 25 equals z squared

(a)

Find the intercepts with three coordinate axes If they exist as follows

 x equals y equals 0, then 

table row cell 0 squared over 100 plus 0 squared over 25 end cell equals cell z squared end cell row cell z squared end cell equals 0 row z equals 0 end table

so, the intercept is origin i.e left parenthesis x comma y comma z right parenthesis equals left parenthesis 0 comma 0 comma 0 right parenthesis.

Put,x equals z equals 0 then 

Error converting from MathML to accessible text.

so, the intercept is origin i.e.left parenthesis x comma y comma z right parenthesis equals left parenthesis 0 comma 0 comma 0 right parenthesis.

Put,y equals z equals 0 then 

Error converting from MathML to accessible text.

so, the intercept is origin i.e.left parenthesis x comma y comma z right parenthesis equals left parenthesis 0 comma 0 comma 0 right parenthesis.
