Acertain isotope decays radioactively so that the mass satisfies the equation m′=−0.01m. here the time is measured in days.  what is the half life? [hint: solve the equation then find at what time your solution gives half the inital mass]

Prism m and pyramid n have the same base area and the same height. cylinder p and prism q have the same height and the same base perimeter. cone z has the same base area as cylinder y, but its height is three times the height of cylinder y. the figures and have the same volume.
