A^2 -b^2 / a +b

Apply the difference of two squares formula to the top :

A^2 - b^2 = (a+b)(a-b)

now you have :

(A+b)(a-b) / a+b = 12

the two (a+ b)’s cancel each other out so you are left with a-b = 12

answer: a-b = 12

Find so that the distance between (−2,3) and (,1) is √13

belka [17]

The distance between (-2, 3) and (-5, 1) is √13.

or, the distance between (-2, 3) and (1, 1) is √13.

We know that the length of the line segment connecting any two points represents the distance between them. There is just one line that connects the two points. Therefore, by measuring the length of the line segment that connects the two points, the distance between them can be determined. If (a, b) and (c, d) be two points, then the distance between them is $\sqrt[]{(b - a)^{2} +(d- c)^{2} }$ .

Here, one point is (-2, 3).

Let the other point be (x, 1).

Given that the distance is √13.

Now, $\sqrt[]{(x - (-2))^{2} +(1 - 3)^{2} } = \sqrt{13}$

i.e. $\sqrt[]{(x + 2)^{2} +( - 2)^{2} } =\sqrt{13}$

i.e. $\sqrt[]{x^{2}+4x +4 +4 }=\sqrt{13}$

i.e. $x^{2}+4x +8 =13$

i.e. $x^{2}+4x + 8- 13=0$

i.e. $x^{2}+4x -5=0$

i.e. $x^{2} +5x - x -5=0$

i.e. $x(x+5)-1(x+5)=0$

i.e. $(x+5)(x-1)=0$

i.e. $x=-5,1$

So, the point is either (-5, 1) or (1, 1).

Therefore, the required point is either (-5, 1) or (1, 1).

i.e. the distance between (-2, 3) and (-5, 1) is √13.

or, the distance between (-2, 3) and (1, 1) is √13.

Division in ratio: A company has a policy that the ratio between its full time employees and its part time employees should be f

DanielleElmas [232]

Answer:

a) 2.5

b) 12

c) 40

Step-by-step explanation:

a) The ratio would be the relation between fixed and part time employees: for this would be 25/10= 2.5 Fixed per part time employee

b) Previous we got the ratio. So we have to divvide the 30 fixed by 2.5 to meet units

c) b) Previous we got the ratio. So we have to multiply the 16 for 2.5 to meet units

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

son4ous [18]

Answer: a & b

Step-by-step explanation:

The sum of the probabilities should equal 1.0

a) probability of 5/3 is greater than 1 shows that the probability distributions will result in a sum greater than 1.

b) The sum of the probabilities is 31/12 shows that the sum of the probability distributions is unequal to 1.0.

c) The result is less than 0 is irrelevant. The data could be temperature (or something else which can be measured as a negative value).

d) The probabilities have different denominators is irrelevant. Fractions can be reduced and unlike denominators can be turned into like denominators. The most important thing is that their sum is 1.0.
