The function f(x) = 200(0.5)x/50 models the amount in pounds of a particular
victus00 [196]

<u>Answer:</u>

29 years

<u>Step-by-step explanation:</u>

  • Given the function f(x)= 200(0.5)^{\frac{x}{50} }, where x stands for the number of years since the material was put into the vault, we can plug 140 into x to find the amount leftover.
  • Another way of doing this is to change the function to f(x)=200(0.5^{\frac{1}{50} })^{x} which are equivalent functions, and then plug 140 into x. This function is helpful if you also needed to find the rate.
  • I'll use the 1st function because the question doesn't ask for the rate

f(x)= 200(0.5)^\frac{140}{50}}

From here I'll just use a calculator & get 28.7, or 29 years.

Answer:

Approximately 439.6 square millimeters.

Step-by-step explanation:

The formula for the surface area of a cone is the following:

A=\pi r^2+\pi r l

Where, <em>r </em>is the radius and <em>l</em> is the slant height.

The radius is 7 and the slant height is 13. We also use 3.14 for π Thus:

A=(3.14)(7)^2+(3.14)(7)(13)\\\text{Use a Calculator}\\A\approx 439.6

ZanzabumX [31]

Answer:

2730 possible ways

Step-by-step explanation:

Given

Applicants = 15

Positions = 3

Required

Number of possible selections

Since there is no restriction, the number of selection is calculated as:

The day nursing supervisor position can be occupied by any of the 15 applicants

The night nursing supervisor position can be occupied by any of the remaining 14

The nursing coordinator position can be occupied by any of the 13

So, the number of ways is then calculated as:

Ways = 15 * 14 * 13

Ways = 2730

<em>Hence, there are 2730 possible ways</em>
