Answer:
11x + 12
Step-by-step explanation:
9x + 3x = 11x
8 + 4 = 12
B. Because a domain is the "x" value and on a graph you would notice the the "x" are all positive numbers (to the left). Hope that made sense. A range is the "y" value and are negative numbers (to the right) on a graph just in case you would like to know that as well:)
The amount of Tritium that bottle contains now will be 439,421.
<h3>What is an exponent?</h3>
Consider the function:
y = a (1 - r)ˣ
Where x is the number of times this decay occurs, a = initial amount, and r = fraction by which this decay occurs.
Tritium is a radioactive isotope of hydrogen that rots by around 5% each year. An enormous container of water that contained 856,000 tritium iotas stayed undisturbed for a very long time.
Then the amount of Tritium that bottle contains now will be given as,
y = 856,000 (1 - 0.05)¹³
Simplify the equation, then we have
y = 856,000 (1 - 0.05)¹³
y = 856,000 (0.95)¹³
y = 856,000 (0.51334)
y = 439,421
The amount of Tritium that bottle contains now will be 439,421.
