Hello,
y=sin²(cos(2x))
y'=2*sin(cos(2x))*cos(cos(2x))*(-sin(2x)*2)
= -4*sin(cos(2x))*cos(cos(2x))*sin(2x)
If you would like to know about how far does a car travel in 7.1 seconds, you can calculate this using the following steps:
51.3 feet ... 1 second
x feet = ? ... 7.1 seconds
51.3 * 7.1 = x * 1
x = 51.3 * 7.1
x = 364.23 feet
The correct result would be 364.23 feet in 7.1 seconds.
Slope = (6 - 3)/(-2-2)
= 3/-4
= -3/4
answer
slope = -3/4
Total cost= (24 times 4)+(10 times 2)
96 + 20 = 116
cost: $116
