Suppose p" must approximate p with relative error at most 10-3 . Find the largest interval in which p* must lie for each value o

goblinko [34]

Answer:

$[p-|p|*10^{-3} \, , \, p+|p|* 10^-3]$

Step-by-step explanation

The relative error is the absolute error divided by the absolute value of p. for an approximation p*, the relative error is

r = |p*-p|/|p|

we want r to be at most 10⁻³, thus

|p*-p|/|p| ≤ 10⁻³

|p*-p| ≤ |p|* 10⁻³

therefore, p*-p should lie in the interval [ - |p| * 10⁻³ , |p| * 10⁻³ ], and as a consecuence, p* should be in the interval [p - |p| * 10⁻³ , p + |p| * 10⁻³ ]

Find the distance between the pair of points: (6,−3) and (1,0

rosijanka [135]

Hi there!

»»————-　★　————-««

I believe your answer is:

$\sqrt{34}$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\text{\underline{The distance formula is:}}\\\\d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

⸻⸻⸻⸻

$\boxed{\text{Calculating the answer....}}\\\\d = \sqrt{(1-6)^2+(0-(-3))^2}\\--------------\\\rightarrow d = \sqrt{(-5)^2+(3)^2}\\\\\rightarrow d = \sqrt{(25+9)}\\\\\rightarrow d =\boxed{ \sqrt{34} }$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

1.) The answer is Letter A - the credit monitoring service alerts you when there is a change in your credit report.

2.) The answer is Letter D - Financial software can do all of the following except applying for loans.

3.) The answer is 34.78. Use the amount in 11/1 as your balance, then compute by deducting the checks (chk) and debit purchases and adding the deposits. Then get the difference.

Check Register:
Total = 397.45 - 50.32 - 16.32 + 190.67
Total = 521.48

Online Statement:
Total = 486.44 - 84.80 - 19.73 - 16.32 + 190.67
Total = 556.26

Difference = online - check register
Difference = 34.78

4.) The answer is 206.99. On 11/10 and 11/18, check and online have the same transactions (same date, same amount) which are 16.32 and 190.67. Add them together to get 206.99
