determinant: 
(a) 
D<0 means there are no real roots. there are two complex roots with imaginary components.
(b) D=16+20=36>0
D>0 means there are two real roots
(c) D = 20^2-4*4*25 = 0
D=0 means there is one real root with multiplicity 2

Step-by-step explanation:
Answer:
40.7m^2
Step-by-step explanation:
Base×Height= 5.2m×3=15.6m2
Area of semicircle= Pie r^2= Pie×4^2=16×pie
pie×16÷2=8×pie
8×3.14=25.12m2
15.6m2+25.12m2=40.72m2
rounded to nearest tenth=40.7m2

Step-by-step explanation:
Length is stored in variable named length
the width in one named width
the expression for the diagonal of the rectangle can be written as
double diagonal = Math.sqrt(Math.pow(length,2) + Math.pow(width,2))
