y=70
step by step explanation:
In the question,
<em>Si</em><em>nce</em><em> </em><em>the</em><em> </em><em>trian</em><em>gle</em><em> </em><em>two</em><em> </em><em>sides</em><em> of</em><em> the</em><em> </em><em>traingl</em><em>e</em><em> </em><em>is</em><em> </em><em>equal</em><em>,</em><em> </em><em>it</em><em> </em><em>is</em><em> </em><em>an</em><em> </em><em>isosc</em><em>eles</em><em> </em><em>triangle</em><em>.</em>
<em>For</em><em> </em><em>an</em><em> </em><em>isosc</em><em>eles</em><em> triangle</em><em>,</em><em> </em><em>angles </em><em>oppos</em><em>ite</em><em> </em><em>to</em><em> </em><em>eq</em><em>ual</em><em> </em><em>sides</em><em> </em><em>are</em><em> </em><em>equal</em><em>,</em>
<em>Hence</em><em>,</em>
<h2>We know that</h2>
The initial height is 20 feet above the ground.
The function to model the velocity is
Where <em>s</em> represents the distance in feet.
Mathematically, this function has all real numbers as a domain. However, that will no make sense for this situation, because it would use negative numbers for the distance <em>s</em> which does not make sense.
Therefore, the domain, in this case, would be all real numbers greater than or equal to zero, but less than or equal to 20.
<em>The reason for this domain is that the ball will go from 20 feet above the ground to zero feet on the ground.</em>
