Write the inverse variation function given that y varies inversely with x, and y = 0.25 when x = 8.

storchak [24]

Answer:

Step-by-step explanation:

If a given variable varies inversely with another variable, an increase in the value of the given variable would cause a corresponding decrease in the value of the other variable. Also, a decrease in the value of the given variable would cause a corresponding increase in the value of the other variable.

If y varies inversely with x, we would introduce a cost of variation, k so that the expression becomes

y = k/x

When y = 0.25, x = 8

Substituting into the expression above, it becomes

0.25 = k/8

k = 0.25 × 8

k = 2

The inverse variation function is

y = 2/x

What is the explicit formula for the geometric sequence with this recursive formula?

weeeeeb [17]

Answer:

A

Step-by-step explanation:

The explicit formula for a geometric sequence is

$a_{n}$ = a₁ $(r)^{n-1}$

where a₁ is the first term and r the common ratio

The recursive formula gives a term in the sequence by multiplying the previous term by r

Given the recursive formula

a₁ = - 6

$a_{n}$ = $a_{n-1}$ ( $\frac{1}{4}$ )

with r = $\frac{1}{4}$

Then explicit formula is

$a_{n}$ = - 6 $(\frac{1}{4}) ^{n-1}$ → A
