Marco is studying a type of mold that grows at a fast rate. He created the function f(x) = 345(1.30)x to model the number of mol
2 answers:
1.30 represents the rate of growth of the mold spores. This decimal is a representation of the percentage growth, which would be 130%.
Since the function is written in terms of weeks, x will equal 4 to represent the amount of spores after 4 weeks. Plug the value into the function:
Rounded to the nearest ones value, there will be 985 mold spores after 4 weeks.

Answer:
P = 80
A = 480²
Step-by-step explanation:
To solve for the base we use the Pythagorean Theorem
then we multiply by 2 to get the side length
2x5=10
this is an 8 sided figure with congruent sides so to get the perimeter we multiply 8 and 10
8x10=80 so the perimeter is 80
To find the area of a regular polygon we multiply the apothem (12) and the perimeter (80) and divide by 2
12x80=960
960/2=480
the area is 480²
