Answer:
Initial amount = 8
Decay rate = 15%
Step-by-step explanation:
Given the exponential function :
y = 8(1 – 0.15)
The general form of an exponential Decay function is :
A = P(1 - r)^t
Where
A = final amout ; P = initial amount ; r = days cay rate ; t = time
Hence, comparing with the equation given :
P = 8 = initial amount
r = 0.15 = 0.15 * 100% = 15% = Decay rate
4/15 should be your answer!
<span>A(C)=9x^2-25/3x+5 = [3x+5)(3x-5)] / (3x -5) = 3x + 5
</span><span>The zero of the function,
3x + 5 = 0
3x = -5
x = -5/3
answer
</span><span>-5/3</span>
