1 answer:

8 0

If it is, then you can solve the equation by taking the square root of both sides of the equation. ... Next, if the coefficient of the squared term is 1 and the coefficient of the linear (middle) term is even, completing the square is a good method to use. Finally, the quadratic formula will work on any quadratic equation

1.Which explains why the sequence 216, 12, 2/3 is arithmetic or geometric?

Free_Kalibri [48]

Hi Timothy,

1.Which explains why the sequence 216, 12, 2/3 is arithmetic or geometric?

Answer - C.The sequence is geometric because it decreases by a factor of 1/18

The reason I chose C is the fact that the numbers go down greatly, and it has to to be geometric because when you are trying to solve the problem with arithmetic you don't get and exact rule for how to solve the problem.
