Step-by-step explanation:
The zeroes of f(x) are -2, -3 and 2.
Hence f(x) = (x + 2)(x + 3)(x - 2) = (x + 3)(x² - 4) = x³ + 3x² - 4x - 12.
<h3>
Answer:</h3>
1) Radius: 2√7
2) Center: (10, 5)
3) Circumference: 33.25
<h3>
Explanation:</h3>
Circle formulae:
where (h, k) is the center coordinates, r is radius
Rewrite the equation into standard form:
- (x-(10))² + (x - (5))² = (√28)²
Identify following of the circle:
- h = 10, k = 5, radius = √28 = 2√7
In order to find the Circumference of circle:
- Use the formula: 2π(radius)
radius: 2√7
- Circumference: 2π(2√7) = (4√7)π = 33.2475 = 33.25
Answer:
first = 65
second = 325
Third = 165
Step-by-step explanation:
Let the first number = x
first: x
second: 5x
Third = x + 100
first + second + third = 555
x + 5x + x + 100 = 555 Combine
7x + 100 = 555 Subtract 100 from both sides
7x + 100 - 100 = 555 - 100
7x = 455 Divide by 7
7x/7 = 455/7
x = 65
D. When a pair of parallel lines are intersected by a third line, all of the angles formed are congruent.
