Let a =107° and b=42°;
So cos 107° cos 42° + sin 107° sin 42° = cosa.cos42 + sina.sinb = cos(a-b)
and cos 107° cos 42° + sin 107° sin 42° = cos(107-42) = cos(65°)

Answer:
1.5 seconds
Step-by-step explanation:
plug 0 in for y
0=-16t^2+36
then slove for t
-36=-16t^2
-36 / -16 = 9/4
9/4=t^2
square root of 9/4 is 3/2 or 1.5
t=1.5
60/8=7.5
So that means one child is $7.50
195/7.5=26
