Answer:
i think its C)
Step-by-step explanation:
I think it's B. 13/10 * 4
Explanation:
It's +0.3 more servings, so it would rule out C and D, which uses the digit 7(nothing to do with this problem.
13/10 instead of 3/10 because it's adding 0.3. More than 4L
Y = 2x + 12
2(4) + 12 = 8 + 12 = 20
She spends $20
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
