Satellite power. The power supply of a satellite is a radio- isotope (radioactive substance). The power output P, in watts (W), decreases at a rate proportional to the amount present; P is given by P = 50e-0.0041 where t is the time, in days. a) How much power will be available after 375 days? Watts ( Give your answer to exactly 2 decimal places) (Give the numerical answer only)Satellite power. The power supply of a satellite is a radio- isotope (radioactive substance).

Its velocity, in miles per hour, is given by: v ( 1 ) = Vi+ 1, where t is the number of hours since the particle left the origin.

The velocity as a function of time is modeled by the function v(t) = - 1.19712 + 58.67 where v is in feet per second, t is in seconds and 0 = ( $ 7 How far did the vehicle travel while the driver was braking
