If cos(w°) = sin(z°), which of the following statements is true? triangle ABD and ECD in which angle D measures 90 degrees, angle A equals w degrees, angle B equals x degrees, angle E equals y degrees, and angle C equals z degrees z = x and ΔABD ≅ ΔECD w = z and ΔABD ≅ ΔECD z = x and ΔABD ~ ΔECD w = z and ΔABD ~ ΔECD

Five dinosaurs go for a walk and come across some lovely chicken wings. their names are rexy, bronto, steggy, paly, and terry. there are exactly 5 dozen wings(equal enough for each dino to have a dozen right? ); however, terry is on a diet and he only eats 6 wings. if paly eats 2 more than terry, steggy eats 4 more than paly, and bronto and rexy eat the same amount because they are really hungry from not eating all day, how many chicken wings did each dino eat?

When turned about its axis of rotation, which shape could have created this three-dimensional object?

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
