Simple Interest, I = PRT/100
3240 = 18 000 * R * 6 /100
3240 = 180*R*6
3240 / (180*6) = R Use your calculator
3 = R
The annual interest rate is 3%.
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)
Answer:
The perimeter of the given semi-circle in terms of is
cm
Step-by-step explanation:
Given that the diameter of the semi-circle is 18cm
That is d=18cm
Therefore radius
Therefore radius r=9cm
To find the perimeter of the semi-circle :
perimeter of the semi-circle
cm (where r=9 cm )
cm
The perimeter of the given semi-circle in terms of is
cm
