If A = 8! and B = 8P8, then which one of the following is true:

meriva

Answer:

A. A = B

Step-by-step explanation:

Given

$A = 8!$

$B = ^8P_8$

Required

Which of the options is true

We start by simplifying $B = ^8P_8$

Permutation is calculated as follows

$^nP_r = \frac{n!}{(n - r)!}$

So.

$^8P_8 =\frac{8!}{(8 - 8)!}$

$^8P_8 =\frac{8!}{0!}$

0! = 1; So

$^8P_8 =\frac{8!}{1}$

$^8P_8 =8!$

Hence. B! = P!

<em>This implies that </em> $A = B = 8!$ <em />

I need help pls someone

Solnce55 [7]

In this question they've given us the formula and they just want us to plug in the numbers and get the value.

P is the original value, P=$600

r is the depreciation rate, r=10%=0.1

t is the time in years, t=2

$A = P(1-r)^t = 600(1 - 0.1)^2 = 600 \cdot .9^2 = 486$

Answer: $486
