Formula:
A(t)=P(1+(r/n))^)nt)
A(4)=2500(1+(0.04/4))^(4*4)
A(4) = 2500(1.01)^16
A(4) = 2500*1.1726
<span>A(4) = $2931.45</span>
interior angle of a regular 18-gon.
It is easier to calculate the exterior angle of a regular polygon of n-sides (n-gon) by the relation
exterior angle = 360/n
For a 18-gon, n=18, so exterior angle = 360/18=20 °
The value of each interior angle is therefore the supplement, or
Interior angle = 180-20=160 degrees.
Naming of a 9-gon
A polygon with 9 vertices is called a nonagon (in English) or enneagon (French ennéagone, but the English version is sometimes used)
You had a good start with the correct answer.
Exterior angle of a 15-gon
The exterior angle of a 15-gon can be calculated using the relation given in the first paragraph, namely
Exterior angle = 360/15=24 degrees
Answer:
f(x) = -1.25(x) + 64
Step-by-step explanation:
Total = $80
Remove $4 + $12 = [$16] for food and entry which leaves us with $64.
For every ride, your friend would spend $1.25 which means that for every ride, you will subtract $1.25 from 64.
f(x) = 64 - 1.25(x) which is also f(x) = -1.25(x) + 64
From the figure, we can notice that :
⊕ There are 4 striped blocks
⊕ The total number of blocks in the block set : 8
The ratio of striped blocks to total blocks in the block set is :
![\sf{\implies \dfrac{4}{8}}](https://tex.z-dn.net/?f=%5Csf%7B%5Cimplies%20%5Cdfrac%7B4%7D%7B8%7D%7D)
![\sf{\implies \dfrac{1}{2}}](https://tex.z-dn.net/?f=%5Csf%7B%5Cimplies%20%5Cdfrac%7B1%7D%7B2%7D%7D)
![\sf{\implies 1 : 2}](https://tex.z-dn.net/?f=%5Csf%7B%5Cimplies%201%20%3A%202%7D)
<u>Answer</u> : B
