a __ -6/8 = -(2 x 3)/(2 x 4) = -3/4
b __ -2/8 = -2/(2 x 4) = -1/4
c __ -4/8 = -4/(4 x 2) = -1/2
d __ 8/8 = 1
e __ 13/8
Using the law of cosines:
The grocery store to the school:
Distance = √(7^2 + 10^2 - 2*7*10*cos(100)
Distance = 13.16 miles
The movie store to the school:
Distance = √(7^2 + 10^2 - 2*7*10*cos(120)
Distance = 14.80 miles
