Hooke's Law states that the force F required to compress or stretch a spring (within its elastic limits) is proportional to the distance d that the spring is compressed or stretched from its original length. That is, 
where k is a measure of the stiffness of the spring and is called the spring constant. The table shows the elongation d in centimeters of a spring when a force of F newtons is applied. Use the model 
data-wiris-created="true" varid="variable_id_field" variablename="impvar_2bd3c58185374af38fca5138b" /> to estimate the elongation of the spring when a force of 45 newtons is applied. Round your answer to two decimal places.
