An object was shot up into the air at an initial vertical speed of 480 feet per second. Its height as time passes can be modeled by the quadratic function , where f(t)=−16^2+480. Here represents the number of seconds since the object’s release, and f(t) represents the object’s height in feet. 1) After, this object reached its maximum height of

2) This object flew for before it landed on the ground.

3) This object wasin the air 26 s after its release.

4) This object was 464 ft high at two times: once after its release, and again later___ after its release.

go and ask your mom to you

i need more info. are you looked to see there mph? how much they deliver? how far they go?

step-by-step explanation:

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
