Answer:
1.42 cm
Step-by-step explanation:
2.5 m = 98.4251 inches
98.4251 in / 11.5 in =8.5587
.5587 inches left over =1.42 cm
Answer: The determinant must be zero.
Step-by-step explanation:
For a quadratic equation
a*x^2 + b*x + c = 0
The discriminant is:
D = b^2 - 4*a*c
and the solutions can be finded as:
If D > 0 we have two real solutions
if D = 0 we only have one solution, x = -b/2a
If D < 0 we will have comples solutions, as we will have a negative number inside a square root.
Knowing that for this equation we have only one solution, then we can know that the determinant must be equal to zero.
That equation is unable to be graphed because a ^ cant be near -<span />
Answer: 28.27
Step-by-step explanation:
A=3.14r^2
A=3.14•3^2
A=3.14•9
A=28.27
