$\sqrt{29}$

Step-by-step explanation:

$d = \sqrt {(2 - 4)^2 + (2 - 7)^2}$

$d = \sqrt {(-2)^2 + (-5)^2}$

$d = \sqrt {4 + 25}$

$d = \sqrt 29$

If p, q, r, and s are consecutive even integers such that p < q < r < s, then how much greater is s - p than r - q ?

Irina18 [472]

Answer:

Whenever you assume values, try and make them as accurate as possible i.e. I am looking for consecutive even numbers so I will assume the values to be (2n - 2), 2n and (2n + 2)

s2−r2−q2=(2n+2)2−(2n)2−(2n−2)2s2−r2−q2=(2n+2)2−(2n)2−(2n−2)2

You get: 4n (4 - n)

So the solution must have 4 as a factor, which we see all options do.

To get -20, n(4-n) must be (-5). It will happen when n = 5.

To get 0, n = 0

To get 12, n(4-n) must be 3. It will happen when n = 3

To get 16, n(4-n) must be 4. It will happen when n = 2

There is no way n(4-n) could be 2 if n is an integer so 8 is not possible.Step-by-step explanation:

Which is better: having a stock that goes up 30% on Wednesday than drops 20% on Thursday, or a stock

finlep [7]

Step-by-step explanation:

If the stock goes up 30%, it's multiplied by $1.3$ .

The reason is that $x + .3 \times x=1.3\times x$

If the stock goes down 20%, it's multiplied by $0.8$

The reason is that $x - .2 \times x = 0.8 \times x$

If the stock goes down 30%, it's multiplied by $0.7$

The reason is that $x - .3 \times x = 0.7 \times x$

If the stock goes up 40%, it's multiplied by $1.4$ .

The reason is that $x + .4 \times x=1.4\times x$

If you increase it by 30% and then drop it by 20%, it means you are multiplying it by $1.3$ and then multiplying it by $.8$ . In other words:

$1.3 \times 0.8=1.04$

So, the net gain is = .04

Assume the original value = 500

Increase it by 30% and it becomes 650

Decrease 650 by 20% and it becomes 520

So, the net gain = 20

Verification:

$500 \times .04=20$

And

If you drop it by 30% and then increase it by 40%, you are multiplying it by .7 and then multiplying it by 1.4. In other words:

$.7 \times 1.4=0.98$

So, the net loss is = 1 - 0.98 = .02

Assume the original value = 500

Decrease it by 30% and it becomes 350.

increase 350 by 40% and it becomes 490.

So, the net loss is = 10

Verification:

$500 \times .02=10$
