Concept explainers
The stated intent of the 1994 “don’t ask, don’t tell” policy was to reduce the number of discharges of gay men and lesbians from the military. Nearly 14,000 active-duty gay servicemembers were dismissed under the policy, which officially ended in 2011, after 18 years. The line graph shows the number of discharges under “don’t ask, don’t tell” from 1994 through 2010.
a. For the period shown, in which year did the number of discharges reach a maximum? Find a reasonable estimate of the number of discharges for that year.
b. For the period shown, in which year did the number of discharges reach a minimum? Find a reasonable estimate of the number of discharges for that year.
c. In which one-year period did the number of discharges decrease at the greatest rate?
d. In which year were approximately 1000 gay service-members discharged under the ‘don’t ask, don’t tell” policy?

- (a) Let P be a point not on the line L that passes through the points Q and R. Show that the distance d from the point P to the line L is |a x bl |a| d where a = QR and b = QP. This answer has not been graded yet. (b) Use the formula in part (a) to find the distance from the point P(1, 1, 1) to the line through Q(0, 7, 6) and R(-1, 2, 6). 29.65arrow_forwardFind the area of the parallelogram with vertices K(1, 2, 2), L(1, 5, 4), M(6, 10, 4), and N(6, 7, 2).arrow_forwardFind the area of the parallelogram with vertices A(-5, 4), B(-3, 7), C(1, 5), and D(-1, 2).arrow_forward
