X is inversely proportional to y, and x = 18 when y = 4. Write an equation relating the two
Alenkasestr [34]

Answer:

xy=72

Step-by-step explanation:

If x is inversely porportionaly to y, then for some constant k,

x = \frac{k}{y}\\xy=k

Since y is 4 when x = 18, k is equal to 4*18=72, so the equation is:

xy=72

Find the first four terms of the recursive sequence defined by the following formula: an = an-1 4 where a4 = 2 1 4 , , , 2 1 4.
Elina [12.6K]

The first four-term of the sequence is found by the given equation a_{n-1} = 4a_n is given as 144, 36, 9, and 9/4.

<h3>What is a sequence?</h3>

A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.

The given equation will be

\rm a_n = \dfrac{a_{n-1}}{4} \\\\a_{n-1} = 4a_n

And

a_4 = 2 \dfrac{1}{4} = \dfrac{9}{4}

For n = 4, we have

\rm a_{4-1} = 4a_4\\\\a_3 \ \ \  = 4*\dfrac{9}{4} \\\\ a_3 \ \ \ = 9

For n = 3, we have

\rm a_{3-1} = 4a_3\\\\a_2 \ \ \  = 4*9 \\\\ a_2 \ \ \ = 36

For n = 2, we have

\rm a_{2-1} = 4a_2\\\\a_1 \ \ \  = 4*36 \\\\ a_1 \ \ \ = 144
