Answer:
A
Step-by-step explanation:
Because if you simplify you get that
Answer:
The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).

Answer:

Step-by-step explanation:
If the radius of the algae was approximately 13.29 mm, substitute f(d)=13.29 and solve for d to determine the domain:

B. The y-intercept is obtained when d=0, hence;

Therefore, the y-intercept represents that in 0 days the diameter of the algae will be 7 mm.
C. Now, to determine the rate of change of a function, use the following equation:

Then, determine the value of f(4):

Hence, the rate of change on that interval of the function:

This means that on average the algae grows 0.64mm per day.
