$3.25\ divided\ by\ 5.2= \frac{3.25}{5.2} =\frac{3.25\cdot 20}{5.2\cdot20} =\frac{65}{104} =\frac{65:13}{104:13} = \frac{5}{8} =0.625\\\\Ans.\ 0.625$

Answer:

Step-by-step explanation:

Step 1: find the derivative of y = x^2 + 12x - 7; it is 2x + 12.

This function represents the slope of the tangent line to the given curve at x.

Step 2: Substitute 4 for x in f '(x) = 2x + 12: f '(4) = 2(4) + 12 = 20

The slope of the tangent line to the graph of y = x^2 + 12x - 7 at x = 4 is 20.
