Pi/2 falls at 90 degrees on the unit circle, or 0,1. And since sin is the y value, sin (pi/2) = 1
If i can remember, a direct variation is y=kx so find y and x, and you can figure out k. i’m probably wrong, good luck tho! lol
If you would like to know the solution to the equation (x - 2) * (x + 5) = 18, you can calculate this using the following steps:
(x - 2) * (x + 5<span>) = 18
</span>x^2 + 5x - 2x - 10 = 18
x^2 + 3x - 28 = 0
(x + 7) * (x - 4) = 0
1. x = - 7
2. x = 4
The correct result would be x = - 7.
