Anewly discovered planet has a mass of 4.8743 · 10 ^22 kilograms. it's estimated that there is water on the surface and that, the water's mass is only 4 · 10^ -2 percent of the planet's total mass. use scientific notation to estimate the mass of the planet's water. in your final answer, include all of your estimates and calculations.

The equation y=mx+b is the slope-intercept form of the equation of a line. what is the equation solved for b? y-m=b y-mx=b y/mx=b y/m-x=b

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
