The diagonal of a rhombus are 12cm and 16cm. calculate the perimeter of the rhombus.

Although changes result from business transactions, the equality of the fundamental bookkeeping equation must remain. t/f

(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.

Factor completely. 4p^2 + 36p + 81 express the answer in the form (ap + b)^2
