Answer:
40 units
Step-by-step explanation:
An octagon is a polygon with 8 sides. A regular octagon is an octagon in which all their sides and angles are equal to each other.
Since the vertices of a regular octagon are located at (1, 4) and (4,8), hence the length of the side is gotten using the formula for calculating the distance between two points .
Hence:
Since all the sides of a regular octagon are equal, therefore:
Perimeter = 8 × length = 8 × 5 = 40 units
Answer:
Step-by-step explanation:
Formula to be used,
A =
Here, A = Final amount
P = Principal amount
r = rate of interest
n = Number of compounding (In a year)
t = Duration of investment (In years)
Question (5)
P = $4250
r = 0.015
n = 4
t = 3 years
A =
A =
A = $4445.24
Part (C)
1). P = $6000
r = 0.03
n = 2
t = 10 years
A =
=
= $8081.13
2). P = $9000
r = 0.05
n = 2
t = 8 years
A =
=
= $13360.55
