Answer:
The volume of the cone is 
Step-by-step explanation:
we know that
The volume of a cylinder is equal to

In this problem we have that

so
-----> equation A
The volume of a cone with the same radius and height is equal to
-----> equation B
Substitute equation A in equation B


Answer:
• discriminant: 73
• # of real solutions: 2
Step-by-step explanation:
Comparing the equation ...
2x^2 -9x +1 = 0
to the generic form ...
ax^2 +bx +c = 0
we find the coefficient values to be ...
a = 2; b = -9; c = 1
That makes the value of the discriminant, (b^2 -4ac), be ...
(-9)^2 -4(2)(1) = 81 -8 = 73
Since the discriminant is positive, the number of real solutions is 2.

0-(-5) =5. ( big minus small)
