Answer:
C. 10 : 16
Step-by-step explanation:
Attached below
If d=6, there are two real solutions.
Rule if d=discriminant:
d>0, two real solutions
d=0, one real solution
d<0, no real solutions (but there are two imaginary solutions)
The equation r = u/st is equivalent to u = rst .
True
V = 36 pi centimeters cubed
