EF for sure u got to really pay attention to the inches
Answer:
0.72secs
Step-by-step explanation:
Given the height of the ball in air modeled by the equation:
h=−16t²+23t+4
Required
Total time it spent in the air
To get this we need to calculate its time at the maximum height
At the maximum height,
v = dh/dt = 0
-32t + 23 = 0
-32t = -23
t = 23/32
t = 0.72secs
<em>Hence the total time it spend in the air will be 0.72secs</em>
Answer:
71.6°
Step-by-step explanation:
=210s÷60s(1 minutes)
=3.5mins
=3.5mins×3%(=1min)
=10.5%
=100%-10.5%
=89.5%
=89.5%/100×80°
=71.6°
Hope this will help ya!
