If there are initially 1500 bacteria in a culture, and the number of bacteria double each hour, the number of bacteria after t hours can be found using the formula N=1500(2^t). How many bacteria will present after 7 hours?
I think the answer is N=192,000. Is this correct?
1500*2^7=1500*128=192,000
Yes the answer is correct!
Well, let's see if we can multiply those bacteria like bunnies in a magic hat! We have N = 1500(2^t), and we want to know the number of bacteria after 7 hours. So let's substitute t with 7 and calculate.
N = 1500(2^7)
N = 1500(128)
N = 192,000
So, you're absolutely right! After 7 hours, there will be a whopping 192,000 bacteria. That's quite a party they're having in that culture!
To find the number of bacteria after 7 hours using the formula N = 1500(2^t), we substitute t = 7:
N = 1500(2^7)
N = 1500(128)
N = 192,000
So, you are correct. After 7 hours, there will be 192,000 bacteria present in the culture.
To find the number of bacteria after 7 hours, you can use the formula N = 1500 * (2^t), where t is the number of hours. Plugging in t = 7 into the formula:
N = 1500 * (2^7)
N = 1500 * 128
N = 192,000
So your answer, N = 192,000, is correct.
