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]
<span>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.</span>

Assume f(x)=2x+8 and g(×)=5 what is the value of (g o f)(3)
RUDIKE [14]
We first need to find f(3).

f(3) = 2(3) + 8

f(3) = 6 + 8

f(3) = 14

We now want g(f(3)).

We know that f(3) is 14.

We also know that g(x) is 5.

As you know, 5 is a constant. No matter what the value of x is for g(x), it will not change the value of g(x).

So, g(f(3)) = g(14) = 5.

Answer: g(f(3)) = 5.

How much is a 20% tip
GenaCL600 [577]
That would depend on the price u r originally paying because ur tip is a percentage of the original price.

Lets say u went out to eat and ur meal costs u $ 40. U plan on leaving a 20% tip. So ur tip would be 20% of 40....0.20 * 40 = 8...so a 20% tip on ur meal would be $ 8.

but if ur meal cost $ 25....and u left a 20% tip....20% of 25 = 0.20 * 25 = 5...so if ur meal was $ 25 and u left a 20% tip, u would be tipping $ 5
