For the triangle with vertices P(-2, 0), Q(4, 6), and R(5, -3), find an equation for the median from: a) vertex P

b) vertex Q

Show your calculations.

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.

Solve the equation using the given values: x= -2.5; y= -7.51. 2xy + 2x²

Consider the graph of the exponential function y=3(2)×
