How is anybody supposed to find the answer to this pre calc express the complex number in trigonometric form. -2 how am i supposed to do anything with that number? these are my choices, but i am completely lost! : 2(cos 90° + i sin 90°) 2(cos 0° + i sin 0°) 2(cos 180° + i sin 180°) 2(cos 270° + i sin 270°)

Which of the following tables represents exponential functions?

Iam a rectangle. my perimeter is 60 feet. how much are do i cover?

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
