Answer:

\displaystyle  {5}^{ - 3}  =   \boxed{\frac{1}{ 125} }

Step-by-step explanation:

we would like to evaluate the following expression:

\displaystyle  {5}^{ - 3}

recall that,

\displaystyle  {x}^{ - n}  =  \frac{1}{ {x}^{n} }

let x be 5 thus substitute:

\displaystyle  {5}^{ - 3}  =  \frac{1}{ {5}^{3} }

simplify:

\displaystyle  {5}^{ - 3}  =   \boxed{\frac{1}{ 125} }

Hello!

Here are 6 steps to Help You Out!

1. 3 divided by 50 = .06

2. Then if you like you can turn it in to a percent not sure how the answer is supposed to look for example:

<span><span>3. 3/50</span>=<span>6/100</span>=6%

</span>4. 7 divided by 50 - .14

5. so 0.06 for the first one

6. And 40 divided by 50 = .8

====>So as we can see, o<span>pen side up .06 closed side up .14 and  on its side .8 or open 6% closed 14% and side 80% chance.<====

Hope this Helps! Have A WONDERFUL Day! :)</span>

Mallory puts $1.00 in a jar. The following week, she puts 2 times that original amount in the jar. For each of the next six week
Burka [1]

The relationship of the ordered pair that represents Mallory savings is a nonlinear relationship.

Let x represents the number of weeks, and y represents the amount put in the jar, each week.

So, we have the following highlights for 6 weeks.

  • Week 1: (1, 1)
  • Week 2: (2,2)
  • Week 3: (3,4)
  • Week 4: (4,8)
  • Week 5: (5,16)
  • Week 6: (6,32)

The ordered pairs can then be represented as:

(x,y) = (1,1)(2,2)(3,4)(4,8)(5,16)(6,32)

As the x values increase, the y values increase too, but the y values do not increase at a constant rate.

This means that the relationship is not linear; it is an exponential relationship.

Hence, the relationship is a nonlinear relationship.
