Answer:
22.1 meters
Step-by-step explanation:
To calculate the height of the box at 1 second after it was tossed upward, we just need to use the equation of the height that the question gave us - h(t) - using the time t = 1:
h(t) = -4.9*t^2 + 9*t + 18
h(1) = -4.9*1^2 + 9*1 + 18
h(1) = -4.9 + 9 + 18 = 22.1 meters
The height of the box at 1 second is 22.1 meters.
Answer:
22.1 meters
Step-by-step explanation:
The equation for the height of the box is given by:
[tex]h(t)=-4.9t^2+9t+18[/tex] where t is time in seconds.
After 1 second,
The height of the box
[tex]h(1)=-4.9(1)^2+9(1)+18\\=-4.9+9+18\\=22.1 \:meters[/tex]
