Write a recursive function for the following geometric sequence ,6,18,54,162

Mathematics
1 answer:
sasho [114]4 years ago
5 0

Answer:

f(n + 1) = 3f(n) with a₁ = 6

Step-by-step explanation:

The common ratio r of the geometric sequence is

r = 18 ÷ 6 = 3

Thus to obtain the next term in the sequence multiply the previous term by 3

Expressing this as a recursive function then

f(n + 1 ) = 3f(n) with a₁ = 6

*No Links* I'll give brainlist to Whoever answers it correctly
Aloiza [94]

Answer:

The solution to the inequality is x≥5.5. This means there is no solution because there are only 4 stores that carry the color LeighAnn wants.

Step-by-step explanation:

2x+3 ≥ 14

2x ≥ 11

x ≥5.5

because ·x is the number of shop, it mean she needs 6 shops.

However there are only 4 shops that serve the paint she need.

So there is no solution.

Simple calculation and it is in the line with the actual situation

Noemi wants to divide 2x^2−x+4 by x−5 using synthetic division.Which answer shows the correct process? A synthetic division diag
STALIN [3.7K]

Answer:

2x + 9 with a remainder of 45.

Step-by-step explanation:

If the divisor is x-5, use the divisor 5 in synthetic div.

Taking the coefficients 2, -1 and 4 from the dividend, we get:

    ------------------

5  /    2    -1    4

              10   45  

    --------------------

       2       9   49

This tells us that the quotient is 2x + 9 and that the remainder is 49.
