Answer:
A. cos(60°)
Step-by-step explanation:
sin(30 degrees) = 0.5
cos(60°) = 0.5
cos(90°) = 0
sin(60°) = √
cos(30°) = √
so it's A.

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.
