Slope would be undefined because there are many many y-values for one x value. This is impossible for ANY function. To be specific, the correct equation that names the graph is x=4. Please note that this is not a function. If it goes straight up, it is UNDEFINED!!!

Hope I helped!

The answer is D

Plutonium-240 decays according to the function Q(t)=Q(subscripto)e^(-kt) where Q represents the quantity remaining after t years

svetoff [14.1K]

The answer is 9,990 years. Using the exponential decay question, we can figure out how long it will take Plutonium-240 to decay from 27 grams to 9 grams. Setting the equation up looks like this, 9 = 27 e^ (-0.00011 t). From this you get, 0.333333 = e ^(-0.00011 t). Next, you simplify by dividing both sides by the natural log, -1.0986 = -0.00011 t. Finally, you solve by dividing both sides by -0.00011, giving 9,987 years for t, rounded up to 9,990 years.
