The after 9/4 seconds the football is at its highest point which is 81 feet if Lillian kicks a football. Its height in feet is given by h(t)= -16t²+72t
<h3>What is a parabola?</h3>It is defined as the graph of a quadratic function that has something bowl-shaped.
Making perfect square:
The highest point will be when term (4t-9)² becomes zero
So the highest point = 81 feet, and it takes:
t = 9/4 seconds
Thus, the after 9/4 seconds the football is at its highest point which is 81 feet if Lillian kicks a football. Its height in feet is given by h(t)= -16t²+72t

Answer:
Step-by-step explanation:
Point-slope formula is represented by the equation . When knowing a point a line crosses through and its slope, you can write an equation in this form. Substitute the
,
, and
for real values.
The represents the slope of the line. Since we know the slope is -2, substitute -2 for
. The
and
represent the x and y values of the point the line passes through. Since the line passes through (4, -6), substitute 4 for
and -6 for
. This gives the following answer and equation:
Answer:
Use the cross technique if it’s name like that in English but , I wish you can understand it from what I‘ve written .
