Step-by-step explanation:
C.
π/9 is less than sqrt(9) / 3 which is 1. Also, this question is quite ambiguous, and the answer could be none, because sqrt(9)/3 can also be -1
Answer:
The cosine of the angle is: negative
The sine of the angle is: positive
Step-by-step explanation:
Question 1:
For this case we have that the function
is undefined or discontinuous where the denominator equals 0.

Thus, the function is undefined or discontinuous at +5 and -5.
To find the zeros of the function we match the function to zero and clear "x":

Factoring the denominator, taking into account that the roots are -5 and +5:

We multiply by
on both sides of the equation:

ANswer:
Discontinuity: + 5, -5
Zero: x = 0
Question 2:
For this case we propose a system of equations:
x: Be the variable that represents the yellow fish
y: Be the variable that represents the green fish

We manipulate the second equation:

We substitute in the first equation:

So, we have 12 yellow fish in the aquarium.

So, we have 18 green fish.
Answer:
12 yellow fish
18 green fish
