The radioactive isotope carbon-14 is present in small quantities in all life forms, and it is constantly replenished until the o

rganism dies, after which it decays to stable carbon-12 at a rate proportional to the amount of carbon-14 present, with a half-life of 5556 years. Suppose C(t) is the amount of carbon-14 present at time t. The exponential decay differential equation that models this scenario is C'=-kC . Solve the differential equation to answer the following questions.
(a) Find the value of the constant k in the differential equation.

bija089 [108]

Answer:

B. 7 inches

Step-by-step explanation:

The surface area of a cube is denoted by: A = 6s², where s is the side length.

Here, we know that A = 294 in², so plug this into the equation to solve for s:

A = 6s²

294 = 6s²

s² = 49

s = √49 = 7

The answer is thus B, 7 inches.
