Hell fast plz what is the sum of the roots in this equation 2x^2+5x-3=0 a. -3.5 b. -2.5 c. -1.5 d. 2.5

2x^2 + 5x -3 = 0 can be factored as:
(2x - 1)(x + 3) = 0; to find roots, set each set of parentheses equal to zero;
2x - 1 = 0; 2x = 1, so x = 1/2 = ROOT 1
x + 3 = 0, so x = -3 = ROOT 2
Now add the roots: -3 + 1/2 = - 2 1/2, so the answer is B.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
