A number, n, is rounded to 2 decimal places.

frosja888 [35]

Using rounding concepts, it is found that the error interval for n is:

$3.865 \leq n < 3.875$

The number is rounded to two decimal places, hence:

If the third decimal digit is 5 or more, one is added to the second decimal digit.
If the third decimal digit is of 4 or less, the second digit stays the same.

From this, we have that values between 3.865(inclusive) and 3.875(exclusive) are rounded to 3.87, which means that the error interval is:

$3.865 \leq n < 3.875$

$19.\\y=3x^2\\a=3,\ b=0,\ c=0\\\\\dfrac{-b}{2a}=\dfrac{-0}{2(3)=0\to x=0\\\\3x^2=0\ \ \ \ |:3\\\\x^2=0\to x=0$

$20.\\y=x^2-x-2\\a=1,\ b=-1,\ c=-2\\\\\dfrac{-b}{2a}=\dfrac{-(-1)}{2(1)}=\dfrac{1}{2}\to x=\dfrac{1}{2}\\\\x^2-x-2=0\\\\x^2-2x+x-2=0\\\\x(x-2)+1(x-2)=0\\\\(x-2)(x+1)=0\iff x-2=0\ \vee\ x+1=0\\\\x=2\ \vee\ x=-1$
