Answer:
The correct option is B.
Step-by-step explanation:
The number of members of an online community increases each month. It is represented by the function
Where N is the initial number of members and r is the rate of increase.
The initial value for the function is N, because at t=0 the value of M is N. So, option A is incorrect.
The value of M is product of N and . The second term is free from N, because second term does not contain N. therefore the second factor does not depend on N. So, option B is correct.
It is an exponential growth function, therefore it can not be linear. So, option C is incorrect.
The initial value is constant. In the given function only the value of t can be changed. So, option D is incorrect.
Answer:
<h2>£1,330.46</h2>Step-by-step explanation:
Using the compound interest formula
A = amount compounded after n years
P = principal (amount invested)
r = rate (in %)
t = time (in years)
n = time used to compound the money
Given P = £1200., r = 3.5%, t = 3years, n = 1 year(compounded annually)
Value of Charlie's investment after 3 years is £1,330.46
