Answer:

-3.86

Step-by-step explanation:

Replace x with 19.

f(19) = 3/(19+2) - √19-3

f(19)= 1/7 - 4

f(19) = -3.86

Answer:

(-65)/17

Step-by-step explanation:

Evaluate 3/(x - 2) - sqrt(x - 3) where x = 19:

3/(x - 2) - sqrt(x - 3) = 3/(19 - 2) - sqrt(19 - 3)

19 - 3 = 16:

3/(19 - 2) - sqrt(16)

19 - 2 = 17:

3/17 - sqrt(16)

sqrt(16) = sqrt(2^4) = 2^2:

3/17 - 2^2

2^2 = 4:

3/17 - 4

Put 3/17 - 4 over the common denominator 17. 3/17 - 4 = 3/17 + (17 (-4))/17:

3/17 - (4×17)/17

17 (-4) = -68:

3/17 + (-68)/17

3/17 - 68/17 = (3 - 68)/17:

(3 - 68)/17

3 - 68 = -65:

Answer: (-65)/17

insens350 [35]

Answer:

13.9%

Step-by-step explanation:

Given data

Expected weight = 230 pounds

Actual weight= 262 pounds

Required

The percent error

Error= Actaul- expected/ expected *100

Error= 262-230/230*100

Error=32/230*100

Error=0.139*100

Error=13.9%

Hence the error is 13.9%

The perimeter of a square in which A=169cm square root 2?
sergey [27]
I'm guessing you mean:
A = 169 \sqrt{2}

If not, correct me. 

So, then the perimeter of a square is just 4*A, which in this case would be:
4(169 \sqrt{2}) = 676 \sqrt{2}

And that would be your answer: 676 \sqrt{2} units²
