In a geometric sequence, if a3 = ‒5 and a6 = 40, determine a1, r, and an. Then write the first three terms of the sequence.
Tresset [83]
a_4=ra_3
a_5=ra_4=r^2a_3
a_6=ra_5=r^3a_3

40=-5r^3\implies r^3=-8\implies r=-2

a_3=ra_2=r^2a_1

-5=(-2)^2a_1\implies a_1=-\dfrac54

You know the first and third terms, a_1 and a_3, so you just need to find the second term a_2:

a_2=ra_1\implies a_2=-2\left(-\dfrac54\right)=\dfrac52

Which criterion can be used to prove ABC and ADC are congruent?
exis [7]

Ratio of the heights of two similar cones is 7/9


what is the ratio of their radii? ratio of their volumes??


TIA


If they are similar, the ratio of the radaii is the same.


Now consider that the volume of a cone is 1/3 PI r^2 * h


So the volume ratio will have a (7/9)^2 * 7/9 ratio
