7. IODINE lodine 131 is a radioisotope that is related to nuclear energy, medical diagnostic and treatment procedures, and natural gas production. A scientist is
testing 50 milligrams of lodine 131. The scientist knows that the half-life of
χ
lodine 131 is about 8.02 days. The function y = 50(3) 502 represents the amount
of lodine 131 remaining in milligrams y after x days.
a. Identify key features.
b. Graph the function.
c. Identify relevant domain and range.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

the answer is $42.96
