The square root for 18 is 4.242.... , not sure how you want it estimated
aev [14]3 years ago

Another way to estimate sqrt(18) is to understand that

sqrt(18)

=sqrt(9)sqrt(2)

=3sqrt(2)

=3*1.414

=4.242


Note: estimate for sqrt(2) can be by common usage, or the fact that 14*14=196.

memorizing a few square-roots is an advantage in these situations:

sqrt(2)=1.41421356

sqrt(3)=1.7320508

sqrt(5)=2.2360680

etc.

In what ways does adding a constant or coefficient to a quadratic equation affect the graph?
erastova [34]
<span>If you are adding a constant, then the graph is either raised or lowered k units.

For example.... If you have the graph of y = x^2 and now you add 3, so your new graph of x^2 + 3, will be the same graph as x^2 but raised vertically 3 units.
 
The graph of x^2 - 7 will be the graph of x^2 lowered vertically 7 units.


I hope my answer has come to your help. God bless and have a nice day ahead!</span>
