She can buy 5 games and 5 songs and still have money left
Sara has completed the 50m freestyle in 27.47 seconds and Hannah finish the course in 28.68 seconds.
now the question is asking us how to find a difference between those stats so what we do is find the difference between Hannah and Sarah
Answer:
-4.71239 rad
Step-by-step explanation:
Answer: (2*3) = 6
(2*9) = 18 6+ 18 = 24
(3+9) = 12
Step-by-step explanation:
So whats missing is times 2 on the right side next to (3+9) *2
(2×3)+(2×9)=. (3+9)*2
I am not sure how you would approach this using the chain rule, but I can use the quotient rule.
The derivative of cos(u)=-sin(u)
The derivative of sin(u)=cos(u)
The quotient rule states:
[f'(x)g(x)-f(x)g'(x)] / [g(x)]^2
f'(x)= -sin(x)
g(x)= [1+sin(x)]
f(x)= cos(x)
g'(x)= cos(x)
Plug in:
[-sin(x)*[1+sin(x)] - [cos(x)*cos(x)] / (1+sin(x))^2
Simplify by distributing
-sin(x) - sin^2(x) - [cos(x)*cos(x)] / (1+sin(x))^2
Multiply the cos(x)*cos(x)
-sin(x) - sin^2(x) - cos^2(x) / (1+sin(x))^2
That is the answer or the answer could be simplified further by pulling out the negative.
- [sin(x)+sin^2(x)+cos^2(x)] / (1+sin(x))^2
