determine whether each statement makes sense or does not make sense, and explain your reasoning. A tangent line to a circle is a line that intersects the circle at exactly one point. The tangent line is perpendicular to the radius of the circle at this point of contact. Write an equation in point-slope form for the line tangent to the circle whose equation is \(x^{2}+y^{2}=25\) at the point \((3,-4)\)
give the center and radius of the circle described by the equation and graph each equation. Use the graph to identify the relation's domain and range. $$ (x+4)^{2}+(y+5)^{2}=36 $$
If \(f(x)=3 x+7,\) find \(\frac{f(a+h)-f(a)}{h}\)
Explain how to determine whether a relation is a function. What is a function?
complete the square and write the equation in standard form. Then give the center and radius of each circle and graph the equation. $$ x^{2}+y^{2}+3 x+5 y+\frac{9}{4}=0 $$
