1. An arrow is shot from the top of a platform. The path of the arrow can be modelled by
the relation h = -0.005(t - 26)^2 + 5, where h is the height of the arrow in metres and
f is the time in seconds after the arrow was shot.
Calculate the height after 10 seconds
saying "idk" is not much help.
h(10) = -0.005(10 - 26)^2 + 5 = -0.005 * 256 + 5 = ____
To calculate the height of the arrow after 10 seconds, you need to substitute the value of t as 10 into the given equation and solve for h.
The equation is: h = -0.005(t - 26)^2 + 5
Substituting t = 10, we have:
h = -0.005(10 - 26)^2 + 5
Now, we simplify the equation step by step:
h = -0.005(-16)^2 + 5
h = -0.005(256) + 5
h = -1.28 + 5
h = 3.72
Therefore, the height of the arrow after 10 seconds is 3.72 meters.
