Answer:
3125 bacteria
Step-by-step explanation:
Let r(0) be the initial amount of bacteria. Every hour, r(n) decreases by half. So, after one our new value for r(n) = (1/2)r(0). After two hours, r(n') = (1/2)r(n) = (1/2)(1/2)r(0) = (1/2)²r(0).
After n hours, r(n) = (1/2)ⁿr(0)
So when n = 4 hours and r(0) = 50,000, then
r(4) = (1/2)⁴r(0)
r(4) = (1/2)⁴ × 50,000
r(4) = (1/16) × 50,000
r(4) = 3125
So, after 4 hours, we have 3125 bacteria present.
Hello!
First you find what numbers give you the same perimeter
9 + 9 + 6 + 6 = 30
5 + 5 + 8 + 8 = 26
7 + 7 + 4 + 4 = 22
6 + 6 + 8 + 8 = 28
The choice that has the same perimeter is D
The answer is D) 6 centimeters by 8 centimeters
Hope this helps!
