aight slide it here big boy
So, the area of a circle is a=pi r^2
so do that and get a=pi(4)
and since the circle touches the edge of the rectangle, the rectangle is 4 cm tall, so 4*8 is 32 and pi(4) is about 12.56, so 32-12.56 is 19.44, and I believe that is the answer. (19.4)
If this can be modelled by exponential decay, therefore
the function must be in the form of:
A = Ao (1 + r)^t
where A is the final value, Ao is the initial = 15000, r
is the rate of decay = -0.0015, t is time = 2010 – 1990 = 20
A = 15,000 (1 – 0.0015)^20
A = $14,556.36
Answer:
A and B
Step-by-step explanation:
using the law of exponents
• 
= 
, hence
= 
→ A
note that (- 3)² = 9 = 3², hence
= (3²)³ = 
→ B
