Answer:

Step-by-step explanation:

h(x)=ax^2

Given h=30 when x=150 we get

a(150)^2=30

a=30/22500=1/750 so

h(x)=x^2/750

Write a recursive rule an explicit rule for each arithmertic sequence. 67 ,37 ,7, -23, -53
spin [16.1K]

The recursive formula of the sequence is aₙ = aₙ₋₁ - 30

<h3>How to determine the recursive formula of the sequence?</h3>

From the question, we have the following sequence that can be used in our computation:

67 ,37 ,7, -23, -53

In the above sequence, we can see that the 30 is subtracted from the previous term to get the current term

Using the above as a guide,

So, we have the following representation

aₙ = aₙ₋₁ - 30

The above represents the recursive rule

Hence, the recursive rule of the function is aₙ = aₙ₋₁ - 30
