Mamont248 [21]

Answer:the new price of the shoe is $5

Step-by-step explanation:

The price at which the shoe has been selling is $25.

Because of an increase of 4% in wholesale prices, a shoe store had to mark up its new stock by the same percent. The value of the 4% increase on the initial price of the shoe is

4/100 × 25 = 0.04 × 25 = $1

Therefore, the new price of the shoe would be

4 + 1 = $5

Prove that sequence an = (3^n)/(2n)! is monotone

krek1111 [17]

When $n=1$ , you have $a_1=\dfrac3{2!}=\dfrac32$ .

When $n=2$ , you have $a_2=\dfrac{3^2}{4!}=\dfrac38$ .

Clearly, $a_1>a_2$ .

Assume $a_k$ . Now when $n=k+1$ , you have

$a_{k+1}=\dfrac{3^{k+1}}{(2k+2)!}=\dfrac3{(2k+2)(2k+1)}\times\dfrac{3^k}{(2k)!}=\dfrac3{(2k+2)(2k+1)}a_k$

Therefore by induction the sequence is monotone (decreasing).
