So the distance formula: d = rad (x2 - x1)^2 + (y2 - y1)^2
it doesn't matter what order you do, you just have to make sure it's a y coordinate for y and an x coordinate for x.
rad (9-5)^2 + ((-6)-1)^2
rad 4^2 + (-7)^2
rad 16 + 49
rad 65
The answer is 40.
1000/25 will give you the new ratio
Simple way of thinking about it
25 enlisted men = 1 officer
1000enlisted men = X officer
Cross multiply (25 by X officer and the 1 officer by the 1000)
25x = 1000
X= 40.
This would be the term referred to as a line segment. I hope this helps!
In partial-quotients<span> division, it takes several steps to find the </span>quotient<span>. At each step, you find a </span>partial<span> answer (called a </span>partial quotient); then you find the product of thepartial quotient<span> and divisor and subtract it from the dividend. Finally, you add all the</span>partial quotients<span> to find the final </span>quotient<span>.</span>
<h3>Answer:</h3>
±12 (two answers)
<h3>Explanation:</h3>
Suppose one root is <em>a</em>. Then the other root will be -3<em>a</em>. The product of the two roots is the ratio of the constant coefficient to the leading coefficient:
(<em>a</em>)(-3<em>a</em>) = -27/4
<em>a</em>² = -27/(4·(-3)) = 9/4
<em>a</em> = ±√(9/4) = ±3/2
Then the other root is
-3<em>a</em> = -3(±3/2) = ±9/2 . . . . . . the roots will have opposite signs
We know the opposite of the sum of these roots will be the ratio of the linear term coefficient to the leading coefficient: b/4, so ...
-(a + (-3a)) = b/4
2a = b/4
b = 8a = 8·(±3/2)
b = ±12
_____
<em>Check</em>
For b = 12, the equation factors as ...
4x² +12x -27 = (2x -3)(2x +9) = 0
It has roots -9/2 and +3/2, the ratio of which is -3.
For b = -12, the equation factors as ...
4x² -12x -27 = (2x +3)(2x -9) = 0
It has roots 9/2 and -3/2, the ratio of which is -3.
