Answer:
circumference is 50.24cm
Step-by-step explanation:
π
= 200.96
r =
=
=8
Circumference = 2πr = 2 x.3.14.x 8 = 50.24
We don't really have to put this in slope intercept form; it would clearly end up as
y = -4x + something
so we know the slope is -4.
Answer: C) -4
I say go with -(1/2) ^ 750
I=PRT
I=Interest
P=principal
R=rate in decimal
T=time in years
1year=12months
72months/12months=6 years
t=6
given
I=8925
P=35000
R=r
T=6
8925=35000*r*6
8925=210000*r
divide both sides by 210000
0.0425=r
the interest rate is 4.25%
