The given parabola has equation:
We compare this to the general equation,
Comparing the coefficient of x, we have:
-4p=-1
The focus is (-p,0)
The equation of the directrix is
x=p
Answer:
Step-by-step explanation:
The given numbers and their categories are;
1) is not a natural number, because, natural numbers are whole number positive integers. It is not an integer, because it is a fraction.
It is a real number, because it has no imaginary part and it is a rational number because it can be expressed as a fraction
2) √11 is not a rational number, because it cannot be expressed as a fraction, and it is real number because it has no imaginary parts.
Therefore, is an irrational and real number
3) 125; The options selected are correct
4) 4·∛125 = 4 × 5 = 20; The options selected are correct
5) 7. = 710/99; Therefore, 7.
is a rational number and it is also a real number as all natural, whole, integers, rational, and irrational numbers are real numbers
We get;
