Question

Estimate √55 to the nearest whole number.

Answer 1

\[\LARGE f(x+ \Delta x)= f(x)+\Delta x(f'(x))\]
Let \(\Large f(x)=\sqrt{x}\)
Replace x with 7 and \(\Delta x\) with 6

Answer 2

7.41

Answer 3

u can say it 7 because it is < 7.5

Answer 4

thank you :)

Answer 5

or
\[\LARGE 7 \times 7=49\]
\[\LARGE 8 \times 8 =64\]
\[\LARGE \frac{64+49}{2}=56.5\]
so it should be the average between 7 and 8
\[\LARGE \frac{7+8}{2}=7.5\]
is the answer
