Given:
The equation of the curve is:
To find:
The gradient (slope) of the given curve at point (2,7).
Solution:
We have,
Differentiate the given equation with respect to x.
Now we need to find the value of this derivative at (2,7).
Therefore, the gradient (slope) of the given curve at point (2,7) is 19.
I think it should be x(ax +b) + c. Not sure though.
When we say bar magnet, this is a kind of magnet that is rectangular in shape and possesses magnetic properties. Based on the statements above, the one that is true regarding a bar magnet is that, its poles cannot be separated into two isolated poles. The answer would be the third option. Hope this helps.
