A certain radioactive isotope decays at a rate of 2% per 100 years. if t represents time in years and y represents the amount of
gregori [183]
We rewrite the equation:
 y = y0 * e ^ (- 0.0002 * t)
 In this equation:
 I = represents the initial amount of the isotope
 We have then:
 89% of the isotope left:
 0.89 * y0 = y0 * e ^ (- 0.0002 * t)
 We clear the time:
 e ^ (- 0.0002 * t) = 0.89
 Ln (e ^ (- 0.0002 * t)) = Ln (0.89)
 -0.0002 * t = Ln (0.89)
 t = Ln (0.89) / (- 0.0002)
 t = 582.6690813
 round to the nearest year:
 t = 583 years
 Answer:
 
There will be 89% of the isotope left in about:
 
t = 583 years

Which of the following statements will always hold true?
lara [203]

Answer:

<h2>The constant growth valuation formula is not appropriate to use unless the company’s growth rate is expected to remain constant in the future.</h2>

Step-by-step explanation:

The value of a stock can be calculated with the <em>constant growth valuation formula</em>, but it's mandatory that the stock has to have a constant growth, because it depends on this rate. Actually, the present value of a stock is calculated with this formula <em>when it can be assumed that its growth is constant.</em>

On the other hand, if the stock value is zero, if it has no growth at all, then, this formula can't be applied, because this variable will be missing.

If you see the image attached, you're gonna look for <em>'g'</em>, which represents the growth rate.

Solve. 4x + 10= 2x – 14
hammer [34]

Answer:

x = -12

Step-by-step explanation:

Step 1: Subtract 2x from both sides

2x + 10 = -14

Step 2: Subtract 10 from both sides

2x = -24

Step 3: Divide both sides by 2

x = -12
