Each of the 5 points would be a 360/5 rotation = 72o
Rotation CLOCKwise will be 2 x 72
COUNTER clockwise = 3 x 72 Pick the answer that works
BD = 2 Use pythag theorem to find sides ab and ad = sqrt2
then DC = 2
and CB = sqrt 8 soooooo 2 + 2 sqrt2 + sqrt8 = 2 + 4 sqrt2
172 = 82 + 162 - 2 (8)(16) cos x solve for x
24000 ( 1+ .01)^ 30 .01 is the interst pr compounding period (2 months) 30 = number of 2 month periods
x : from 6 to -6 is -12 3/4 * -12 = -9 added to 6 is -3
y: from -6 to -2 is +4 3/4 * 4 = 3 added to -6 is -3
Use cos rule
e2 = 102 + 72 - 2 (10)(7) cos 34 solve for e
1000* (1 + .10)3 -1000 = interest in 3 yrs
50 m/h x .5 hr = 25 miles
60 m/h x 1.5 hr = 90 miles
total miles/totaltime = 115 m/ 2 hr = 57.5 m/hr avg
57 is to 63 as CG is to 21
57/63 = CG/21 Take it from here !
