The mass of a radioactive substance follows a continuous exponential decay model. A sample of this radioactive substance has an initial mass of 771 kg and decreases continuously at a relative rate of 8% per day. Find the mass of the sample after five days. Do not round any intermediate computations, and round your answer to the nearest tenth.

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
