Answer:
100,000
Step-by-step explanation:
We are given a function: f(t) = 100,000, where,
f(t) is a function that tells us about the number of people who will be infected in t weeks. Here t that is number of week is the independent variable and f(t) is the dependent variable.
We observe that f(t) is a constant function that is it does not depend on the value of t. Whatever may be the value of t it will always take the constant value of 100,000.
So, after ten weeks that is we put t = 10, we get,
f(10) = 100,000
Thus, after 10 weeks 100,000 people will be infected.
Answer:
Option (c) is correct.
The distance covered by the man in 1 hour is represented by te expression
miles.
Step-by-step explanation:
Given: A man walks 10 miles in x hours.
We have to choose a correct expression that represents the distance covered by the man in 1 hour.
Consider the given statement."A man walks 10 miles in x hours."
Using UNITARY METHOD,
(is a method in which we first find the value of a single unit and then multiply it with desired quantity)
Distance covered by man in x hours = 10 miles,
So distance covered by man in 1 hour =
miles.
So, The distance covered by the man in 1 hour is represented by te expression
miles.
This is the concept of exponential growth, To get the number of bacteria after 10 days we use the formula:
f(t)=ae^(kt)
where;
a=initial number=5000
k=constant of proportionality= 0.04
t=time=10 days
f(t)=future number
thus the number of bacteria in 10 days will be:
f(t)=5000e^(0.04*10)
f(t)=7,459.12
The answer is 7,459.12
