The coin diameter is 34.54. This is because if you add 4 + 4 + 3 you get 12. Then multiply that by 3.14
Answer x=6, y=6√2
Use the 45-45-90 theorem:
45 45 90
s s s√2
6 6 6√2
The discriminant of a quadratic equation is a parameter that is used to determine the nature of the roots of the equation. The discriminant can be determined by b2- 4ac. The standard form of quadratic equation is ax2 + bx + c = 0. Upon substitution, we can easily determine the discriminant. If disc. is zero, the roots are equal; if <0, then the roots are positive and non-identical; if <0, the roots are negative and imaginary.
