Iven cos θ=3√3 and sinθ< 0 .
what is the value of sinθ

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

Ihonestly have no clue if it's each or none.

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585
