Answer:
A) coral reefs provide unique habitats for fish
Step-by-step explanation:
Coral bleaching can be hazardous to some fish species because
A) coral reefs provide unique habitats for fish
B) decomposition of corals can lead to ocean acidification
C) the dead corals attract predators that feed on the fish
D) the corals are the primary source of O2O2 in ocean water
Solution:
Coral bleaching is process in which corals are stressed as a result of changes temperature, light, or nutrients causing them to turn completely white. Coral reefs are is a very diverse ecosystems with ecological and economic value.
Coral reefs are a very important habitat for the fishes providing home to about 25% of fishes. The coral reefs are used for shelter during the day, and as a hunting ground by night.
the answer is c.
sin is 18/30 -------- opposite over hypotenuse
cos is 24/30 ------- adjacent over hypotenuse
tan is 18/24 -------- opposite over adjacent

Answer: (-2, -1)
Step-by-step explanation: Since these lines are already graphed, we are looking for their point of intersection. This point where the two lines intersect will represent the <em>x</em> and <em>y</em> that is the solution to this system of equations.
The two lines intersect in quadrant III
where <em>x</em> and <em>y</em> are both negative.
When finding the coordinates of a given point,
be very careful with your signs.
Let's just do a quick review on the coordinate system. On the x-axis, left means negative and right means positive and on the y-axis, down means negative and up means positive.
So to find the coordinates for this point, we start at the origin.
Then we move to the left 2 and down 1 so that's (-2, -1).
So the solution to this system is (-2, -1).
