If <em>y</em> = cos(√<em>x</em>), then by the chain rule
d<em>y</em>/d<em>x</em> = d/d<em>x</em> [cos(√<em>x</em>)]
d<em>y</em>/d<em>x</em> = - sin(√<em>x</em>) d/d<em>x</em> [√<em>x</em>]
d<em>y</em>/d<em>x</em> = - sin(√<em>x</em>) (1 / (2√<em>x</em>))
d<em>y</em>/d<em>x</em> = - 1/2 sin(√<em>x</em>) / √<em>x</em>
Answer:
D. 12
Step-by-step explanation:
you put the x coordinate in place of c and that cancels it out so the answer is 12
Answer:
9
Step-by-step explanation:
The ladder is the hypotenuse, the wall is one of the legs. In order to find the other leg you have to do c^2-a^2=b^2. 41^2-40^2 is 81 and the square root of that is 9
