(e)
Declare quot1,
a variable of type double, and
set it equal to the equation:
. (You may assume the
variables k, A, x,
y, r, and z
have already been declared as doubles.)
_________double quot1 = Math.pow(A,2)*(r + z) * k / (Math.pow(x+y, 2));___
(f)
Declare quot3,
a variable of type double, and
set it equal to the equation:
. (You may assume the
variables k, A, x,
y, r, and z
have already been declared as doubles.)
___double quot3 = Math.pow(A, 2) * (r+z) / (k * (x+y));_____
(g)
Declare quot4,
a variable of type double, and
set it equal to the equation:
. (You may assume the
variables k, A, x,
y, r, and z
have already been declared as doubles.)
____double quot4 = (r + Math.pow(z, 2)) / (A * k * (x-y));_______
(h)
Declare quot5,
a variable of type double, and
set it equal to the equation:
. (You may assume the
variables k, A, x,
y, r, and z
have already been declared as doubles.)
___double quot5 = Math.pow(k * r - z, 2)/ Math.pow(x + y * A, 2)___
(i)
Declare quot6,
a variable of type double, and
set it equal to the equation:
. (You may assume the
variables k, A, x,
y, r, and z
have already been declared as doubles.)
___double qout6 = r * z / ((x*x + y*y) * (A + k));____
