∆ADC is formed by reflecting ∆ABC across line segment , as shown in the figure. If the length of is 4 units, the area of ∆ADC is square units.

6n^2-7n-75=0 solve by quadratic formula

(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.

Which of the following represents the range of the graph of f(x) below
