Solve the problem.
-Two bacteria are placed in a petri dish. The population will double every day. The formula for the number of bacteria in the dish on day t is $$\mathrm { N } ( \mathrm { t } ) = 2 ( 2 ) ^ { t }$$ where t is the number of days after the two bacteria are placed in the dish. How many bacteria are in the dish
Seven days after the two bacteria are placed in the dish?
A) 98
B) 11
C) 256
D) 28

Quizplus · Accepted Answer

To find the number of bacteria in the dish seven days after the two bacteria are placed in the dish, substitute $t = 7$ into the given formula: $\mathrm{N}(t) = 2(2)^t$. This gives $\mathrm{N}(7) = 2(2)^7 = 2 \times 128 = 256$.

Solve the Problem N(t)=2(2)t\mathrm { N } ( \mathrm { t } ) = 2 ( 2 ) ^ { t }N(t)=2(2)t

Solve the Problem $\mathrm { N } ( \mathrm { t } ) = 2 ( 2 ) ^ { t }$
