Eric starts with 10 milligrams of a radioactive substance. the amount of the
substance decreases by each week for a number of weeks, w. he writes the
expression 10g)" to find the amount of radioactive substance remaining after w
weeks.
andrea starts with 1 milligram of a radioactive substance. the amount of the
substance decreases by 20% each week for a number of weeks, w. she writes
the expression (1 – 0.2)" to find the amount of radioactive substance remaining
after w weeks.
use the drop-down menus to explain what each part of eric's and andrea's
expressions mean.

the answer is 31.27mph

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).
