Answer:
There are 2 solutions:
X=-7.5
X=4.5
**The positive one is 4.5** so it should be that
Step-by-step explanation:
It is true. Perpendicular lines are what we call to two lines that intersect together forming a right angle or an angle measuring 90 degrees. You can easily determine this if you see a horizontal and a vertical line intersect together.
Thank you for posting your question here. I hope the answer below will help.
Vo=110 feet per second
<span>ho=2 feet </span>
<span>So, h(t) = -16t^2 +110t +2 </span>
<span>Take the derivative: h'(t) = 110 -32t </span>
<span>The maximum height will be at the inflection when the derivative crosses the x-axis aka when h'(t)=0. </span>
<span>So, set h'(t)=0 and solve for t: </span>
<span>0 = 110 -32t </span>
<span>-110 = -32t </span>
<span>t=3.4375 </span>
<span>t=3.44 seconds </span>
