Number of members of an online community increases each month. the function m(t) = n(1+r)t represents the number of members at month t, where n is the initial number of members and r is the rate of increase. select the correct statement.

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.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
