Answer:
cos(C)
Step-by-step explanation:
Recall that the sine ratio is opposite over hypotenuse.

Also the cosine ratio is adjacent over hypotenuse.

The tangent ratio does not come close because it doesn't involve the Hypotenuse.

Slope formula:
m = (y2-y1)/(x2-x1)
m = (13-19)/(-3-(-8))
m = (13-19)/(-3+8)
m = -6/5
The slope is therefore -6/5
86.3 / 30 = 2.876
Therfore the answer is D $2.88
600 fish / 9 dolphins = 66.667
9 fish * 66 = 594 fish
600 fish - 594 fish = 6 fish
there are 6 fish left
14x² - x - 3 = 0
14x² - 7x + 6x - 3 = 0
-7x(-2x + 1) -3(-2x + 1) = 0
(-7x-3) & (-2x+1) = 0
Roots: -7x - 3 = 0
-7x = 3
x = -3/7
OR -2x + 1 = 0
-2x = -1
x = 1/2
In short, Your Roots would be 1/2 and -3/7
Hope this helps!
