Answer:
Step-by-step explanation:
Initial Velocity of projection = 89ft/sec
height(ft), t seconds after launching is given by s=-16t^2 + v0t + s0
A) time the projectile will reach a height of 100 ft
s=-16t^2 + v0t
v0 = 89ft/sec
s = 100ft
100 = - 16t² + 89t
-16t² + 89t - 100 = 0
Using the online quadratic equation solver;
t = 4s or t = 1.5625
Yes this graph is a function because the x and y values all have their own independent input and outputs therefore being a function. The domain and range are specific meaning it the graph corresponds to the values given on the graph. There are closed circles meaning the funciotn has value. If they were both open circles the function wouldn't have any value!
This is an insane assignment!! Hope that helps ya out!!
