Answer:
Si
Step-by-step explanation:
100% - 90% = 10%
10% = 0.10 = 1/10
Respuesta: Si
Answer:
D
Step-by-step explanation:
Using the law of logarithms
•
x = n ⇔ x = 
given
x = 4 ⇒ x =
= 81 → D
The time taken for the population of the pig to reach 1000 will be almost four years.
<h3>What is a function?</h3>
A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.
Six guinea pigs are released in an area with no natural predators.
The guinea pig population quadruples every year.
Write a function P that represents the guinea pig population at a given time T measured in years.
Then the function will be

Then the inverse function of P will be

Then the time taken for the population of the pig to reach 1000 will be

The time taken for the element X to decay from 560 grams to 150 grams is 24.7 mins
<h3>How to determine the number of half-lives </h3>
- Original amount (N₀) = 560 g
- Amount remaining (N) = 150 g
- Number of half-lives (n) =?
2ⁿ = N₀ / N
2ⁿ = 560 / 150
2ⁿ = 3.73
Take the log of both side
Log 2ⁿ = Log 3.73
nLog 2 = Log 3.73
Divide both side by Log 2
n = Log 3.73 / Log 2
n = 1.9
<h3>How to determine the time </h3>
- Number of half-lives (n) = 1.9
- Half-life (t½) = 13 mins
t = n × t½
t = 1.9 × 13
t = 24.7 mins
