Reading and literary analysis: which term fits this description?
A comparison that describes one thing in terms of another without a literal equivalence.
An ideal spring obeys F = kx with k = 410 N/m. A force of 4 N is applied within its linear range. Find its extension. Round to 3 decimal places if needed. Answer in m.
An ideal spring obeys F = kx with k = 730 N/m. A force of 36 N is applied within its linear range. Find its extension. Round to 3 decimal places if needed. Answer in m.
An ideal spring obeys F = kx with k = 570 N/m. A force of 50 N is applied within its linear range. Find its extension. Round to 3 decimal places if needed. Answer in m.

From the study guide Derivatives, accumulated change and units
Study guide for Grades 11 to 12: 4 key ideas, including derivative, units and signed integral; 2 worked examples and 3 practice questions. Connect calculations to their meanings and domains.
Derivative: A derivative describes a local rate of change with respect to the independent variable.
Units: If position is measured in metres and time in seconds, its time derivative has units m/s.
Signed integral: A definite integral of velocity gives signed displacement, not automatically total distance.
Critical points: A zero derivative is a candidate for an extremum, not a guarantee. Check the surrounding behavior.
