Answer:

f(x) = |x - 4| + 3

Step-by-step explanation:

Identify (from the graph) the coordinates of the vertex: (4, 3). That +4 tells us that the vertex of the basic function y = |x| has been translated 4 units to the right; that +3 tells us that the vertex has also been translated 3 units up. Consider y = |x-a| + b. Here, b = +3 and a=+4. Thus, the correct function is f(x) = |x - 4| + 3.

After the release of radioactive material into the atmosphere from a nuclear power plant in a country in 1982, the hay in that

galina1969 [7]

Answer:

25.48 days

Step-by-step explanation:

For a radioactive substance, the Amount of the substance remaining A(t) is modeled by the equation

$A(t)=A_0(\dfrac{1}{2})^{\dfrac{t}{t_{1/2}} }$

where

$A_0 =$Initial Amount$\\t_{1/2}=$Half-Life of the Substance$\\t=$Time elapsed$$

In the given problem:

Half Life of the Radioactive Isotope = 8

Initial Amount, $A_0$ =100%=1

A(t)=11% =0.11

Therefore substituting in the model above:

$0.11=1(\dfrac{1}{2})^{\dfrac{t}{8} }\\0.11=0.5^{t/8}\\$Change to Logarithm form$\\Log_{0.5}0.11=\frac{t}{8}\\\frac{Log 0.11}{Log 0.5} =\frac{t}{8}\\3.1844=\frac{t}{8}\\t=8X3.1844=25.4752$
