Answer:howw??
Step-by-step explanation:
Umm how?
10. The volume of the triangular prism is
, then
.
11. The volume of the triangular pyramid is
, then
.
12. They have common base (common triangle). y=7.7, r=23.1, then r:y=23.1:7.7=3.
13. See 10 and 11 for notations in symbols.
1,450 because you would plug 75 in for x
f(x)= 20(75)-50
Discriminant = sq root (-17^2 -4*3*10)
discriminant = sq root (289 -120)
discriminant = sq root (169)
The discriminant is positive so the equation will have 2 rational solutions.
It would be k because anytime a line is dotted it uses the symbol < or >
