Answer:
Time taken = 9987.38 years
Step-by-step explanation:
We have plutonium-240 decays according to the parent function
k is the decay constant,0.00011
k = 0.00011
We need to find how long will it take 27 grams of plutonium-240 to decay to 9 grams.
Q(t) = 9 g
Q₀ = 27 g
Substituting
Time taken = 9987.38 years
Answer:
135,000
Step-by-step explanation:
1.5 hour means 90 minutes
1500 * 90 = 135000
Answer:
A. (0, 5)
Step-by-step explanation:
Physically speaking, the volume of the box and the side of the square cutout are positive value. So that the following inequations must be satisfied:
(1)
(2)
(3)
From (1), (2), (3) we find that:
(1):
(2):
(3):
We see that equation above is the multiplication of a first grade monomial and two first grade binomials, which means that:
In other words, the reasonable domain for this situation is A.
