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:
Step-by-step explanation:
Perimeter of a rectangle = 2(L+W)
L is the length of the triangle
W is the width
If the perimeter of a rectangle is represented by the expression
In order to know what wat each part represents, we will rewrite the given equation in the form 2(L+W).
Given
Perimeter of a rectangle
Compare the given function with the perimeter to get L and W
Hence the following statements explain correctly what each part of the expression represents
- One side of the rectangle measures x (the length)
- One side of the rectangle measures 3x + 1 (the width)
- 2 is the coefficient in each term that represents 2 lengths and 2 widths in a rectangle.
