Danny's truck has a fuel tank with a capacity of 20 gallons of gas. The truck averages 17 miles per gallon of gas. The function M(g) = 17g represents the number of miles that Danny's truck travels on g gallons of gas. What domain and range are reasonable for the function? A. D: 0 ≤ g ≤ 20 R: 0 ≤ M(g) ≤ 340 B. D: 17 ≤ g ≤ 20 R: 20 ≤ M(g) ≤ 340 C. D: 0 ≤ g ≤ 20 R: 17 ≤ M(g) ≤ 340 D. D: 0 ≤ g ≤ 340 R: 0 ≤ M(g) ≤ 20

i think it is c hope that

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

your answer is option c.
