Answer:
The equation of the tangent at x=-6 is
Step-by-step explanation:
The equation of a circle with center (h,k) with radius r units is given by:
The given circle has center (-3,1) and radius 5 units.
We substitute the center and the radius into the equation to get;
To find the slope, we differentiate implicitly to get:
When x=-6;we have
or
From the graph the reuired point is (-6,-3).
We substitute this point to find the slope;
The equation is given by .
We plug in the slope and the point to get:
7,14,21,28,35,42,49,56,63,70,77,84,91,98,105,112,119,126
18,36,54,72,90,108,126
first to get both will be the 126th person
