Yes, you need to use the chain rule. Also you need to use the derivative of arcsin which is in tables.
Derivative of y = arcsin(x) = 1 / [√(1 - x^2)]
Chain rule: Derivative of archsin(cos(2x)) =
y' = 1 / [√(1 - (cos(2x))^2)] * derivative (cos(2x) =
y' = 1 / [√(1 - (cos(2x))^2)] * (- sin (2x)) * 2
y' = -2(sin(2x)) / [√( 1 - (cos(2x))^2]
Answer:
I know that the b portion for the bottom is 86 because thats the atomic number of Rn
Explanation:
Power is a measure of the rate of energy or work done on a system. It has units of energy per time. In SI, Joules per second and is equal to the units of Watts. So, for an 800 Watts hair straightener, the energy transfer per second would be 800 Joules.
D is your answer hope this helps
