0 = 4x²<span> + 2x – 1
this equation is already ordered by degree, so it's in the correct form. the standard form of a parabola is like so: 0 = A</span>x² + Bx - C
that's exactly how you plug values into the quadratic formula. the coefficient for your squared value, A, is 4. take the coefficients from your other numbers as well.
a = 4
b = 2
c = -1
Answer:
cos K = 12/13
Step-by-step explanation:
cos theta = opposite side/ hypotenuse for a right triangle
cos K = 12/13
There is no picture but ok
