Step - by - step explanation :
6 3/6 -- simplest form --> 6 1/2
6 6/12 -- simplest form --> 6 1/2
Expanded:
y = sin(4x)*sin(4x)*cos(3x)
need to use the product rule and chain rule
look at individual derivatives, use chain rule
d/dx sin(4x) = 4cos(4x)
d/dx cos(3x) = -3sin(3x)
put it together using product rule
dy/dx = 4cos(4x)*sin(4x)*cos(3x) + 4cos(4x)*sin(4x)*cos(3x) - 3sin(3x)*sin(4x)*sin(4x)
simplify
dy/dx = 8cos(4x)*sin(4x)*cos(3x) - 3sin(3x)*sin2(4x)
answer is A.
Answer: He will need 20 feet of fabric .
Step-by-step explanation:
Given: circumference of cushion = 7.85 feet.
Since , circumference = 
, where r = radius.
Area of each piece = 
Area of 2 pieces = 2 x 5 feet = 10 feet
Area for 2 cushions = 2 x (Area of 2 pieces)
= 2 x 10 feet = 20 feet
He will need 20 feet of fabric .
