The director of marketing at a large company wants to determine if the amount of money spent on internet marketing is a good pre
san4es73 [151]
Given:
Profit = 372.60 + 17.2(advertising dollars)
Advertising dollars = 1,020
profit = 17,500

17,500 + residual value = 372.60 + 17.2(1,020)
17,500 + residual value = 372.60 + 17,544
17,500 + residual value = 17,916.60
residual value = 17,916.60 - 17,500
residual value = 416.60

residual value is 416.60 or 417 rounded off to the nearest integer

A rock sample containing an isotope with a half-life of 28 million years has an initial mass of 184 grams. how much time has ela
damaskus [11]
<h2>Half Life</h2>

The half life period is the time in which only half of the given population remains. It can be represented through this equation:

f(t)=a\times(1/2)^{\frac{t}{h}}

  • <em>t</em> = time passed
  • <em>a</em> = y-intercept
  • <em>h</em> = half life

<h2>Solving the Question</h2>

We're given:

  • <em>h</em> = 28 million years
  • <em>a</em> = 184 grams (this is the initial mass, after 0 time has passed)

For most questions like this, we would have to plug these values into the equation mentioned above. However, this question asks for the time elapsed after 3 half-lives.

This can be calculated simply by multiplying the given half-life by 3:

28 million years x 3

= 84 million years

<h2>Answer</h2>

84 million years
