Accepted Solution
A:
Answer:the height of the rock 3.2 seconds after it is propelledStep-by-step explanation:The complete question isThe function h(t) = –16t2 + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshotLett------> the time in secondsh----> the the height of a rock after it is propelled by a slingshot in meterswe know that[tex]h(t)=-16t^{2} +28t+500[/tex]For [tex]x=3.2\ sec[/tex]Find the value of h(t)[tex]h(3.2)=-16(3.2)^{2} +28(3.2)+500=425.76\ meters[/tex]thereforeh(3.2) represent the height of the rock [tex]3.2[/tex] seconds after it is propelledsee the attached figure to better understand the problem
