Answer:
When you're dividing, I only know that one. sorry..
Step-by-step explanation:
For full circle area is π * R² [here R = radius],
for a sector of circle with angle β, area will be = (β/2) * R², β is in radian,
here let β = 22.5° = (π * 22.5/180) = π/8 radian,
now [(π/8)/2] * R² = 9π, [π/16] * R² = 9π
R² = 9 * 16 = 144,
R = √144 = 12 m
A=P(1+R)^n
A=amount in 10 years
P=original amount (200)
R=rate(o.o6)
n=number of times compunded(20)
A=200x1.06^20
=641.4270944
Therefore Rachel will have 641.42 in 10 years
Answer:
The location will be at 
units.
Step-by-step explanation:
A scuba diver descended at a rate of 
units per second.
Now, if 0 represents the surface of the water and distances below the surface are negative, then after 
seconds the location of the diver will be given by the followings :
In one second the diver descends by 2.25 units depth.
So, in 12.5 seconds the diver will descend by 
units i.e. 
units depth.
Therefore, the location will be at units. (Answer)
