An object is launched from a platform. it's height (in meters), x seconds after the launch, is modeled by: h(x) = -5x^2 + 20x + 60. what is the height of the object at the time of launch?

60 meters

Step-by-step explanation:

The standard form for parabolic motion is

where is the initial upwards velocity and is the initial launching height.  If I am understanding your question, this is what you are looking for.  So the height AT the time of launch was 60 meters.

the infinity sign

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
