After 500 years one would have N nuclei of the original substance.
N = 100 * exp ( -ln(4) ) = 25
LOL.
I guess it is exp( - lamda * t)
Lamda, the decay constant is the ln(2) over the half life.
So we get exp( -ln(2)/250 * 500) or exp ( -ln(4) )

Answer:
Real values of x where x < -1
Step-by-step explanation:
Above the x-axis, the function is positive.
The function is decreasing when the gradient is negative.
The function has a positive

coefficient, therefore the vertex is a local minimum;
This means the gradients are negative before the vertex and positive after it;
To meet the conditions therefore, the function must be before the vertex and above the x-axis;
This will be anywhere before the x-intercept at x = -1;
Hence it is when x < -1.
