How do many calculators evaluate the tangent of an angle? They graph a unit circle to calculate the tangent of an angle.
They use the fact that tangent is sine over cosine to calculate tangent.
The use tables for cotangent of an angle to calculate tangent of an angle.
They include extensive tables to determine the tangent of an angle.

The average number of vehicles waiting in line to enter a parking lot can be modeled by the function f left parenthesis x right x squared over 2 left parenthesis 1 minus x right parenthesis endfraction , where x is a number between 0 and 1 known as the traffic intensity. find the rate of change of the number of vehicles waiting with respect to the traffic intensity for the intensities (a) xequals0.3 and (b) xequals0.6.

Which of the following is true for the relation f(x)=2x^2+1

Based on the graph, what is the initial value of the linear relationship? a coordinate plane is shown. a line passes through the y-axis at -2 and the x-axis at 3.
