(-1.1)*(-1.1)*(-1.1)=-1.331
$7200.. you would find out what 3.5% of $6000 (210) is and then multiply it by 6 (1200) and then add it to the original $6000
The half-life is 29 years.
116 : 29 = 4
So we will have 4 periods of half-life:
( 1/2 )^4 = 1/16
150 g * 1/16 = 9.375 g
Answer:
9.375 g of strontium -90 will remain after 116 years.
Answer:
(f - g)(x) = 4x² + 4x + 5
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 5x² - 3
g(x) = x² - 4x - 8
(f - g)(x) is f(x) - g(x)
<u>Step 2: Find (f - g)(x)</u>
- Substitute: (f - g)(x) = 5x² - 3 - (x² - 4x - 8)
- Distribute -1: (f - g)(x) = 5x² - 3 - x² + 4x + 8
- Combine like terms: (f - g)(x) = 4x² + 4x + 5
