Answer: 2
16-8=8
10-2=8
16-8=10-2
✔️
Both now equal 8 which makes it true
Answer:
D. 60y + 48
Step-by-step explanation:
You distribute (multiply) the 12 to everything inside the parentheses.
12 X 5y = 60y 12 X 4 = 48
60y + 48 is your answer. Hope this helps.
F(7)=3(7)^2+3(7)
3(7)^2+3(7)=168
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.
