Answer:
Step-by-step explanation:
Let A( t , f( t ) ) be the point(s) at which the graph of the function has a horizontal tangent => f ' ( t ) = 0.
But, f ' ( x ) = [ ( x^2 ) ' * ( x - 1 ) - ( x^2 ) * ( x - 1 )' ] / ( x - 1 )^2 =>
f ' ( x ) = [ 2x( x - 1 ) - ( x^2 ) * 1 ] / ( x - 1 )^2 => f ' ( x ) = ( x^2 - 2x ) / ( x - 1 )^2;
f ' ( t ) = 0 <=> t^2 - 2t = 0 <=> t * ( t - 2 ) = 0 <=> t = 0 or t = 2 => f ( 0 ) = 0; f ( 2 ) = 4 => A 1 ( 0 , 0 ) and A 2 ( 2 , 4 ).

Answer:
3/4 of cookie per each friend.
Step-by-step explanation:
Since you have 4 friends, and only have 3 cookies,
the fraction is 3/4. why? because 3/4= 0.75
which makes 0.75x 4 friends= 3 cookies . Each friend will get 0.75 or 75% of cookie which is the same as 3/4.
y = 4
first note that the right side simplifies to 12, equation can be written
= 12 ( multiply both sides by 0.8 )
2y + 1.6 = 9.6 ( subtract 1.6 from both sides )
2y = 8 ( divide both sides by 2 )
y = 4
