Aprojectile that was launched straight up from the ground with an initial velocity of 48 ft/s returned to the ground after 3 s. the height of the projectile t seconds after launch is modeled by the function f(t)=−16t2+48t . what is the maximum height of the projectile, in feet? enter your answer in the box.

F(x)=|x| is shifted down 4 units and to the right 3 units.

Select the correct answer from the drop-down menu. this graph represents the inequality x+2< 4,2x> 3,x+6< 12,2x> 12

The average human heart beats 1.15 \cdot 10^51.15⋅10 5 1, point, 15, dot, 10, start superscript, 5, end superscript times per day. there are 3.65 \cdot 10^23.65⋅10 2 3, point, 65, dot, 10, start superscript, 2, end superscript days in one year. how many times does the heart beat in one year? write your answer in scientific notation, and round to one decimal place.
