Given the coordinates of the triangle, determine the coordinate of its image after a dialation with the given scale factor centered at the origin. 20.A(0,3) B(6,0) C (0,-3);scale factor of 1/3
21.A(-1,3) B(1,1) C(-4,1);scale factor of 2
22.A(4,0) E(2,4) F(-2,-4); scale factor of 1/2

(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.

What is the expression in factored form? -20x^2 - 12x a. 4x(5x+3) b. -4x(5x-3) c. -4(5x+3) d. -4x(5x+3)
