A researcher monitoring the power from solar panels on a Mars lander developed a linear model for the available power output in watts P against the number of days since landing D to help predict the change in power due to dust accumulation the equation is P =215.4-0.422d interpert the P - intercept of t b e equation. A. The p intercept implies that the lander will always have a minimum of 215.4 watts of power available. B . The P - intercept implies power decreases by 0.422 watts per day C. The P intercept implies that the lander had 215.4 watts of power available when it landed D. The P intercept implies that the power increases by 0.422 watts pre day.
