Explain what the horizontal intercept means in the context of the problem. A truck driver has determined that the number of miles he has driven after stopping to refuel, D(t), is a function of how many liters of fuel he has in the truck, t, as: 1. D(t) 400-0.8t Leonardo is painting his living room. The area he has left to paint, A(t), in square feet, is a function of the hours he has spent painting, t, as 2. A(t) 2400-300t 3. Janice is repaying her credit card debt. The amount of debt she owes, P[x), in dollars, car be expressed in terms of the number of months since she started paying it off, x, as: P(x) = 8500-250x

Explanation / Answer

given truck driver D(t)=400-0.8t

vertical intercept t=0

D(0)=400-0.8*0=400

vertical intercet represent the number of miles the truck can drive when tank is full

horizontal intercept represent the number of liters of fuel consumed to reach next filling station

D(t)=0

0=400-0.8t

0.8t=400

t=400/0.8=500

as per chegg rule 1st question is answered
