Compute the requested operating costs as indicated, based on the preceding table and the following information. Car = six-cyl. compact Years driven = first through third year Miles driven = 15,000 first year; 14,000 second year; and 13,000 third year .
Using method 2, the total costs for the first year, $
Second year $
Third year $
And all the other years$ in dollars and cents

3x + 4y -25 =0 represents the amount of change sianna should recieve

15.36 per mile

but forgot to round

i am pretty sure

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
