Answer:
32.1
Step-by-step explanation:
d=sqrt ((x2-x1)^2+(y2-y1)^2 )
Find length of AB
d=sqrt((2-(-4))^2+(0-5)^2)
d=sqrt(6^2+(-5)^2)
d=sqrt(36+25)
d=sqrt(61)
d= around 7.8
Find length of BC
d=sqrt((4-(-4))^2+(10-5)^2)
d=sqrt(8^2+5^2)
d=sqrt(64+25)
d=sqrt(89)
d= around 9.4
Find length CD
d=sqrt((8-4)^2+(7-10)^2)
d=sqrt(4^2+(-3)^2)
d=sqrt(16+9)
d=sqrt(25)
d=5
Find length DE
d=sqrt((4-8)^2+(5-7)^2)
d=sqrt((-4)^2+(-2)^2)
d=sqrt(16+4)
d=sqrt(20)
d= around 4.5
Find length EA
d=sqrt ((4-2)^2+(5-0)^2 )
d=sqrt(2^2+5^2)
d=sqrt(4+25)
d=sqrt(29)
d= around 5.4
P=7.8+9.4+5+4.5+5.4
P=32.1
Answer:
0.09
Step-by-step explanation:
So if you use the Simple interest equation it will begin with:
Interest total = Initial Amount of money x Interest rate per year x Years money is invested for.
Then substitute the values you have been given so:
$6300 = 7000 x Interest rate per year x 10.
This is simplifies to 6300 = 70,000 x Annual Interest rate
You can rearrange this to find the annual interest rate by dividing by 70,000:
Simplifying this would be:
= Interest rate.
The interest rate is 0.09.
Plug 10 in for m
-16 = 10/5 - 18
-16 = 2 - 18
-16 = -16
