Answer:
decay
2% decrease
Step-by-step explanation:
The growth factor is the base of the exponent: 0.98. Its relation to the rate of change is ...
growth factor = 1 + rate of change
0.98 = 1 + (-0.02)
So, the rate of change is -0.02 = -2%. Since the rate of change is a 2% decrease, it represents decay.
Answer:
Area of nonagon = 1044.6 square millimetres.
Step-by-step explanation:
Let side of the nonagon is a
Given:
The perimeter of nonagon is 117 millimetres
Put the perimeter value in above equation
So the side of the nonagon is 13
The area of the nonagon is .
where a is side of the nonagon.
Put value of side in above equation
Therefore, the area of the nonagon is 1044.6 square millimetre.
Answer:
N: n = 5 sides
side length: a = 23.2 m
inradius: r = 15.966 m
circumradius: R = 19.7351 m
Area: A = 926.03 m2
perimeter: P = 116 m
interior angle: x = 108 °
exterior angle: y = 72 °
Description:
We use the calculations on the shape 16 and 23.2. Side length is 23.2. Pi is 16. calculate the numbers and all the answers are added above.
