Hello!
The sin of D would be the opposite side divided by the hypotenuse. As we have no hypotenuse length, neither A or D would work, as the cosine also involves the hypotenuse.
The tangent is the opposite divided by the adjacent. This would be, in terms of D, 24/31. This does not match our option.
In terms of K, the tangent is 31/24.
Therefore, our answer is C) tanK= 31/24
I hope this helps!
Y = 0 so
x^2 + 6x - 40 = 0
(x +10)(x - 4) = 0
x+10 = 0; x = -10
x - 4 = 0; x = 4
answer is C. x = -10 and x = 4
Answer:
x = -0.5 or x = 2
Step-by-step explanation:
Finding solutions graphically is often easier if the equation can be put in the form f(x) = 0. Here, we can do that by subtracting the right-side expression to give ...
(-2x^2 +2) -(-3x) = 0
This could be put in standard form, but there is no need. A graphing calculator can deal with this directly.
The solutions are x = -0.5 and x = 2.
Answer:
a, d, b, c
Step-by-step explanation:
Solution set = {x | x > -4}
