During an epidemic, the number of people who have never had the disease and who are not immune (they are susceptible) decreases exponentially according to the following function, where t is time in days.
f left parenthesis t right parenthesis equals 16,000 e superscript negative 0.04 t
find the number of susceptible people at each time.
(a) at the beginning of the epidemic
(b) after 10 days
(c) after 3 weeks

ans a at the be

step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
