Given:

The equation of the circle is

We need to determine the center and radius of the circle.

Center:

The general form of the equation of the circle is

where (h,k) is the center of the circle and r is the radius.

Let us compare the general form of the equation of the circle with the given equation  to determine the center.

The given equation can be written as,

Comparing the two equations, we get;

(h,k) = (0,-4)

Therefore, the center of the circle is (0,-4)

Radius:

Let us compare the general form of the equation of the circle with the given equation  to determine the radius.

Hence, the given equation can be written as,

Comparing the two equation, we get;

Thus, the radius of the circle is 8

Answers

A polynomial function refers to a function expressed by a polynomial, with only positive integer (non-fraction, non roots) values for the exponents, such as:

(a_(1))^(n) + (a_(2))^(n-1) + (a_(3))^(n-2) +...+ a_(n)

Remember that (1)/(x) can be written as ,

Integers are a subset of Rational Numbers.

True
False

Answers

Answer:

True.

Step-by-step explanation:

Given :Integers are a subset of Rational Numbers.

To Find : True or False

Solution:

Rational numbers : A rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.

Integer : An integer is a number that can be written without a fractional component

Integer can be written in p/q form with denominator 1

So, Integer is a subset of Rational numbers .

Hence Integers are a subset of Rational Numbers is true.

Final answer:

The statement is true, integers are indeed a subset of rational numbers. This is because every integer can be expressed as a rational number with the denominator as 1.

Explanation:

Yes, it is True that Integers are a subset of Rational Numbers. Rational numbers are defined as any number that can be expressed as the quotient or fraction of two integers, with the denominator not equal to zero. For instance, the number 3/1 is a rational number, and it equals to the integer 3. Integers, on the other hand, can be thought of as rational numbers where the denominator is always 1. Therefore, every integer is a rational number, but not every rational number is an integer.
