Answer:
6
Step-by-step explanation:
sin(angle) = opposite/hypotenuse
sin(60) = a/4√3
√3/2 = a/4√3
a = (√3/2)(4√3) = 2(3) = 6
Run is looking to the right and making a triangle rise is how much it rises until it gets to the line
So F(m) because F dollars for every mph over the speed limit
so 40 dollar speeding fine so +40
10 dollars for every mile over and m=miles over so put them all toghether and get
F(m)=10m+40
1.
so if you were going 78 mph
to find the mph over you would do 78-70=8mph over so put in 8 for m and get
F(8)=10(8)+40=80+40=$120 fine for going at 78 mph
