Simple question 

Derivative of \boxed{f(y)= (y^2)/(y^3+8) }

Answers

Answer 1
Answer: Let's go ;D

f(y)=(y^2)/(y^3+8)

we have to use the quotient rule.

f(y)=(g(y))/(h(y))

f'(y)=(h(y)*g'(y)-g(y)*h'(y))/([h(y)]^2)

Then

g(y)=y^2

g'(y)=2y

h(y)=y^3+8

h(y)=3y^2

Now we can replace

f'(y)=(h(y)*g'(y)-g(y)*h'(y))/([h(y)]^2)

f'(y)=((y^3+8)*2y-(y^2)*3y^2)/((y^3+8)^2)

f'(y)=(2y^4+16y-3y^4)/((y^3+8)^2)

\boxed{\boxed{f'(y)=(16y-y^4)/((y^3+8)^2)}}

Answer:

D) The function is positive for all values in the domain.

Step-by-step explanation:

From the given graph,  we know that "x" values represents the domain and the y-value represents the range.

In the graph shows all the x - values, That is x tends to both the directions -∞ to ∞.

You can in all values of x, the y remains greater than 0.

It means, the y value is always positive whatever x values.

Therefore, the function (y) is positive for all values of x.

Answer: D) The function is positive for all values in the domain.

Seattle Washington received rain on 7/10 of the day and a recent months if this pattern continues about how many days would it not rain in 90 days

Answers

If I understood correctly:

on 7 out of 10 days it's raining? so on 3 out of 10 days it is not raining. (10-3=7)

and the question is: in 90 days, on how many of those would it rain and on how many not? ( correct me if I'm wrong, I think You had some typos and I couldn't understand the question)

so in 90 days there are 9 times 10 days. If in every one of those 10 days on 7 it's raining, then it's raining on 9*7=63 days!

and days when it is not raining are: 90-63=27!
