Answer:

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

Answer:
answer is
x1= 1/2 + 1/2 * i *sqrt(5)
x2= 1/2 - 1/2 * i *sqrt(5)
Step-by-step explanation:
Please refer to the attached picture for the procedure
Keep in mind, that the first step to use the quadratic formula is to rearrange the terms.
Answer:
28/8=3.5...so probably just 3

Answer:
62
Step-by-step explanation:
Since you know that JK + KL = JL, this would be:
27 + 3x - 1 = 5x + 2
Now, solve this equation:
combine like terms first
subtract 3x from both sides
subtract 2 from both sides
divide both sides by 2
Since you want to find JL and JL = 5x + 2, plug x = 12 into that equation.
