Over twenty years, it was found that the number of doctors of medicine, MD (in thousands), in 28,390+693t
the United States can be approximated by MD =
where t = 0 represents 1980. The
85-t
776-12t
number of doctors of osteopathy, DO (in thousands), can be approximated by DO =
65-2t
a. Write an expression for the total number I of doctors of medicine (MD) and doctors of
osteopathy (DO). Simplify the result.
b. How many MDs did the United States have in 2010? How many DOs did the United States
have in 2010?

step-by-step explanation:

i agree because i see the other persons thinking is clear

we know that

major arc is defined as the bigger arc connecting two points on the edge of a circle. measure of major arc is always more than ° or π radian

in this problem

the mayor arc is bac

find the ratio of the measure of the major arc to the measure of the minor arc

therefore

the answer is the option
