<h2><u>Circle Equations</u></h2>
<h3>Write the standard form of the equation of the circle with the given characteristics.</h3><h3>Center: (0, 0); Radius: 2</h3>
To determine the equation of a circle, use the standard form of a circle (x - h)² + (y - k)² = r² where,
- <u>(h, k)</u> is the center; and
- <u>r</u> is the radius
Substitute the values of the center and radius to the standard form.
<u>Given:</u>
<u>(0, 0)</u> - <u>center</u>
<u>2</u> - <u>radius</u>
- (x - h)² + (y - k)² = 2²
- (x - 0)² + (y - 0)² = 4
- x² + y² = 4
<u>Answer:</u>
- The equation of the circle is <u>x² + y² = 4</u>.

Answer:
Margie spent 60% of time in doing science Homework
Step-by-step explanation:
Given:
Time spent in doing maths homework = 25 minutes
Time spent in doing science homework = 60 minutes
Break Time = 15 minutes
To Find:
A percent to represent the portion of time that Margie spent on science homework = ?
Solution:
Let the portion representing the portion of time that Margie spent on science homework be x
The total time spent in doing both maths and science homework and in break time = Time spent in doing maths homework + Time spent in doing science homework + Break Time
The total time spent in doing both maths and science homework and in break time = 25 +60 +15 = 100 minutes
Then
x =
x =
x = 60%
Answer:
(x - 1) and (x + 4)
Step-by-step explanation:
Given the zeros of a polynomial, say x = a, x = b then the factors are
(x - a), (x - b) and the polynomial is the product of the factors, that is
f(x) = (x - a)(x - b)
Here the zeros are x = 1 and x = - 4, thus the factors are
(x - 1) and (x - (- 4)), that is (x - 1) and (x + 4)
