An object is launched from a platform. Its height (in meters), x xx seconds after the launch, is modeled by: h ( x ) = − 5 ( x − 4 ) 2 + 180 h(x)=−5(x−4) 2 +180h, left parenthesis, x, right parenthesis, equals, minus, 5, left parenthesis, x, minus, 4, right parenthesis, squared, plus, 180 How many seconds after being launched will the object hit the ground?

i think this could be a possible answer (1 / 84) -1

good luck! : d

3x + 4y -25 =0 represents the amount of change sianna should recieve

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
