IF m power n is equal to 32 wher m and n are natural numbers then find the value of n power m

xxTIMURxx [149]

Answer:

$n^m = 5^2$

Step-by-step explanation:

Given

$m^n = 32$

Required

Find $n^m$

$m^n = 32$

Express 32 as an exponent

$m^n = 2^5$

By comparison:

$m = 2$

$n = 5$

So:

$n^m = 5^2$

What is the degree measure of an arc 4 pi feet long in a circle radius of a 10 foot radius

otez555 [7]

Circumference = 2 pi r = 20 pi
corresponding to 360 degrees

so an arc of 4pi feet will have a degree measure of 5pi / 20pi * 360 = 1/4 * 360 = 90 degrees

A swim team must be chosen from 12 candidates. What is the greatest number of different 3-person teams that can be chosen?

grin007 [14]

<h3>Answer: 220 combinations</h3>

==========================================

Explanation:

We have 12*11*10 = 1320 permutations possible. This is where order matters. However, order does not matter with swim teams as there are no positions or ranks. All that matters is the group overall (rather than any individual in the group).

Consider the set {A,B,C}. We have 3*2*1 = 6 ways to arrange this set of letters. When considering a permutation, there are 6 permutations but only 1 combination since order doesnt matter and ABC is the same as BAC. Therefore, we divide 1320 over 6 to get the final answer of 1320/6 = 220.

---------

You can use the combination formula with n = 12 and r = 3. Doing so will give the following:

$_n C _r = \frac{n!}{r!*(n-r)!}\\\\_{12} C _3 = \frac{12!}{3!*(12-3)!}\\\\_{12} C _3 = \frac{12!}{3!*9!}\\\\_{12} C _3 = \frac{12*11*10*9!}{3!*9!}\\\\_{12} C _3 = \frac{12*11*10}{3!}\\\\_{12} C _3 = \frac{12*11*10}{3*2*1}\\\\_{12} C _3 = \frac{1320}{6}\\\\_{12} C _3 = 220\\\\$

As you can see, we get the same result and note how 1320/6 is also present as well.
