Answer:
maybe 220/440?
Step-by-step explanation:
The solution is -4/9x + 1
This is exponential growth/decay type problem...
F=Ir^t, F=final value, I=initial value, r=rate, t=time, in this case I=1250 and r=(1-.045)=0.955 so
F=1250(.955)^t and we want to find t for when F=800
800=1250(.955)^t
.64=.955^t take the natural log of both sides...
ln.64=t ln.955
t=(ln.64)/ln.995
t≈9.69 weeks
t≈9.69 weeks (to nearest hundredth of a week)
BC= DF
B(0,2) , C(3,2)
d= (3-0)^2 + (2-2)^2
d= 9
Square root 9= 3
DF = 3
Hope this helps!
