Answer:
√149 units
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√[3 - (-4)]² + [8 - (-2)]²
√(7)² + (10)²
√49 + 100
√149
Angles could be expressed in degrees or in radians. The relationship between the two could be easily explained by illustrating a circle. A semi-circle has a total angle of 180°. This is equal to a π radians. So if the angle is π/2, in degrees, that would be 180/2 = 90°.
Then, determining the cosine 90° in a calculator would yield an answer of zero.
A negative number is always less than a positive number, so the only positive number, 5/3, is the greatest number of the three. -5/6 is less than -1/6, so the answer is:
-5/6, -1/6, 5/3
Answer:
The number that would go in the blank to get a perfect square trinomial is 18
Step-by-step explanation:
The middle term can always be found by taking twice of the square root of the final term.
2 * √81 = 18
