The cost of an 8x10 piece is $2, and 16x20 is just 2 times that amount, multiply the cost.
Answer:
see explanation
Step-by-step explanation:
Differentiate using the product rule
Given y = f(x)g(x), then
= f(x). g'(x) + g(x). f'(x)
here f(x) =
⇒ f'(x) = 
g(x) = cosx ⇒ g'(x) = - sinx
Hence
=
(- sinx) + cosx 
=
cosx -
sinx
