Which of the following fits with the recursive rule for the dots above?
gogolik [260]

Answer:

A

Step-by-step explanation:

The recursive rule lets us find a term in the sequence from the previous term.

The sequence of dots is

4 , 16, 64

Thus multiplying the previous term by 4 gives the required term, thus

f(x) = f(x - 1) × 4 : f(1) = 4

so

f(2) = f(1) × 4 = 4 × 4 = 16 ← true

f(3) = f(2) × 4 = 16 × 4 = 64 ← true

A is the correct choice

Identify two methods in the Constitution to limit power of the national government?
Dmitry_Shevchenko [17]
First, the principle of Check and Balance applies. The Check and Balance system is devised to have all the branches of the government from overpowering one another. This is done through having independent powers in the government. 

The next would be the principle that states that all powers not under the Federal government would be under the power of the State.
