Answer:
0.01 %
Step-by-step explanation:
The given model is;
y = a (0.5)^t/5730
Which is;
y = a(2^-1(t/5730)
Then;
y = a (2^-1/5730)^t
y = a(0.999879)^t
Hence;
Given that the general model is;
y(x)= a(1-r)^x
Where r is the rate percent
Since 1-r =0.999879
r = 0.00012096
y = a(1 - 0.00012096)^t
So;
r= 0.00012096* 100 = 0.01 %
Step-by-step explanation:
8x-5=9+7x
8x-7x=9+5
x=14
Answer:
2. x= 60° because a triangle is 180°
The zeros of the quadratic function when y = 0
so (-5 , 0) and (-2 , 0)
Answer
C) x = -2 and x = -5
