Answer:
A
Step-by-step explanation:
30% of 4
4÷100=0.04
0.04×30=1.2
Answer:
41.40
Step-by-step explanation: 36*.15=5.40, 36+5.40=41.40
When you write the equation of a circle in the form

Then the center of the circle has coordinates
and the radius is 
So, in your case, the center of the circle is 
Rewrite the equation:
-2x^2 - 3x + 8 = 0
2x^2 + 3x -8 =0
Where a=2, b=3 and c=-8
Then b^2 - 4ac = 3^2 - 4(2)(-8) = 9 + 64 = 73
A positive discriminant implies that the equation has two different real solutions.
Answer: the discriminant is 73, so the equation has 2 real solution
