PLZ HELP!! Peter and Xavier throw a ball in the air and create function models to show the trajectory. The variable x represents time in seconds after the ball was thrown and f(x) represents the height in meters.

The path of Peter's ball is represented by the function, f(x)=−4.9x2+22.54x+1.9.

The path of Xavier's ball is represented by the table.

Select the answers from the drop down menus to complete the statements.

Choose...

ball is thrown from a greater height off the ground.

Choose...

ball reaches a greater maximum height.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
