Given:
The function is,
Use the synthetic division,
The rational roots are of the form,
As, the constant term is -10, its factors are
These are the possible values of p.
Also, the leading coefficient is 1. its factors are
These are the values of q.
From the above synthetic division, the actual rational roots are,
Answer: rational roots are -2, 1
Answer:
The ratio of the slant heights of the two cones will also be n : m.
Step-by-step explanation:
See the attached diagram.
If we take the vertical sections along any diameter of the base circle of the cones A and B then the triangular sections as we get will be similar.
Now, ratio of the base of the triangles A and B i.e. the ratio of the diameters of the cones A and B will be 2n : 2m = n : m and this will be the same as the ratios of other two sides of the triangles A and B.
Therefore, the ratio of the slant heights of the two cones will also be n : m. (Answer)
