Show that the statement is true. If DE has endpoints D(-1,8) and E(7,-2), then the midpoint M of DE lies in Quadrant I.

D. M lies in (select)

since the x-coordinate is (select)

The midpoint M is

and the y-coordinate is (select)

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day

13.46

step-by-step explanation:

16.80 x .20 = 13.46

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
