Answer:

The 49th term is 39.

Step-by-step explanation:

This is a decreasing arithmetic sequence. We recognize this because the difference from one term to the next is 5.

The general formula needed here is a(n) = a(1) - 5(n - 1)

a(45) = 261 - 5(46 - 1), or

a(45) = 261 - 225 = 39

The 49th term is 39.

Step-by-step explanation:

so we know the probability of drawing a 9 is 25 percent or 1/4 because 9 is only one and doesn't repeat.

So the cards we drawn cards we drawn 2 times so multiply 1/4 times two.

Find the inverse of the function.

asambeis [7]

Answer:

A) $f^{-1}(n)= (n+2)^3$

Step-by-step explanation:

$f(n) = \sqrt[3]{n} -2$

$y = \sqrt[3]{n} -2$

$y = n^{1/3}-2$

$n = y^{1/3} -2$

$n + 2 = y^{1/3}$

$y = (n + 2) ^3$

$f^{-1}(n) = (n + 2)^3$

Hope this helps!
