Java Please $1.$Write a program that computes and displays the value of the second$-$order

polynomial $y=a{x}^2+bx+c$ for any user input values of the coefficients $a,b,c$

and the variable $x.$

Write a program to calculate and display the coordinates of the midpoint of the

line segment connecting the two end points $(3,7)$ and $(8,12).$ Use the fact that the

coordinates of the midpoint between two points having coordinates $(x1,y1)$ and

$(x2,y2)$ are $(\frac{x1+x2}{2},\frac{y1+y2}{2}).$

W rite a program to calculate and display the value of the slope of the line

connecting the two points whose coordinates are $(3,7)$ and $(8,12).$ Use the fact the

slope between two points having coordinates $(x1,y1)$ and $(x2,y2)$ is

$\frac{y2-y1}{x2-x1}.$

Write a program to calculate the length of the hypotenuse of a write triangle with

sides $x$ and $y.$ recall that the formula for this is hypot $=\sqrt[\phantom{2}]{x**x+y**y}.$
