If a right circular cone intersects a plane that runs parallel to the edge of the cone, the resulting curve will be a(n)?
a. circle
b. ellipse
c. parabola
d. hyperbola

Option C is correct.i.e., we get Parabola if a cone is cut parallel to its edge.

Step-by-step explanation:

Given: A Right Circular Cone

To find: Shape of of cross section when cone is cut by a plan parallel

             to edge of cone

Cone has an apex on top and circle in base so if it is cut parallel to its edge we get a shape which is curved or pointy on one end while on the other end  it is open due to circle.

Option A: Circle is closed from everywhere,

Thus it is not correct.

Option B: Ellipse is also not open from any end.

Thus, it is not correct.

Option C: Parabola is curved from one end and open from other end.

Thus this is correct.

Option D: We get parabola if cone is cur parallel to axis.

Thus it is also not correct.

Therefore, Option C is correct.i.e., we get Parabola if a cone is cut parallel to its edge.

the answer is true.

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
