An airplane is flying at an altitude of 36,000 feet when it begins its descent for landing. Twelve minutes into its descent, it's at 29,400 feet. Find the rate of change in altitude.

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
