Answer: 340m
Explanation:
Given that:
Streets are constructed from 10 m pieces;
A lamppost is placed at both ends and at every 10 m along its length ;
A lamppost is also placed at every notice board along its length :
Given that:
Einstein Street has 42 lamppost and 7 notice boards :
So,
7 lamppost for 7 notice boards :
Lamppost left = 42 - 7 = 35 lamppost
2 lamppost placed at both ends :
Lamppost left = 35 - 2 = 33 lamppost
Hence, the remaining is placed at 10 m along its length:
Hence, length of Einstein street :
33 lamppost each placed 10m from the starting lamppost = (33 * 10) = 330m
Distance between 33rd lamppost and the ending lamppost = 10m
Hence, total length = (330 + 10) = 340 m
- The initial number of bacteria present is equal to 270 bacteria.
- The number of bacteria that will be in the petty dish after 12 hours is 167818 bacteria.
<h3>What is an exponential function?</h3>
An exponential function can be defined as a mathematical function whose values are generated by a constant that is raised to the power of the argument. Mathematically, an exponential function is represented by this formula:
f(x) = eˣ
<h3>How to calculate the initial number of bacteria?</h3>
B(t) = 150e^0.585t
When t = 1, we have:
B(1) = 150e^0.585(1)
B(1) = 150e^0.585
B(1) = 269.25 ≈ 270 bacteria.
<h3>How many bacteria will be in the petty dish after 12 hours?</h3>
B(12) = 150e^0.585(12)
B(12) = 150e^7.02
B(12) = 167817.99 ≈ 167818 bacteria.
