Answer:
D) - 11
Step-by-step explanation:
![g(2) = 3(2) - 4 \\ = 2 \\ \\ f(g(2)) = f(2) \\ = - 2(2) {}^{2} - 3 \\ = - 11](https://tex.z-dn.net/?f=g%282%29%20%3D%203%282%29%20-%204%20%5C%5C%20%20%3D%202%20%5C%5C%20%20%5C%5C%20f%28g%282%29%29%20%3D%20f%282%29%20%5C%5C%20%20%3D%20%20-%202%282%29%20%7B%7D%5E%7B2%7D%20%20-%203%20%5C%5C%20%20%20%3D%20%20-%2011)

Answer:
kelly drove 55 miles in one hour because if you divide 440 by 8 you get 55 and alberto drove 52 so kelly drove the farthest and she drove 3 mils further
Step-by-step explanation:
Answer:
470.4 Miles
Step-by-step explanation:
The distance between two points
is obtained using the distance formula:
Distance![=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
Given Town A at (4, 8) and Town B is at (7, 17).
Distance between A and B is:
![AB=\sqrt{(7-4)^2+(17-8)^2}\\=\sqrt{(4)^2+(9)^2}\\AB=\sqrt{97} \approx 9.8\\$Since .5 Units=24 Miles\\1 Unit =48 Miles\\Therefore:\\9.8 Units = 9.8 X 48 =470.4 Miles](https://tex.z-dn.net/?f=AB%3D%5Csqrt%7B%287-4%29%5E2%2B%2817-8%29%5E2%7D%5C%5C%3D%5Csqrt%7B%284%29%5E2%2B%289%29%5E2%7D%5C%5CAB%3D%5Csqrt%7B97%7D%20%5Capprox%209.8%5C%5C%24Since%20.5%20Units%3D24%20Miles%5C%5C1%20Unit%20%3D48%20Miles%5C%5CTherefore%3A%5C%5C9.8%20Units%20%3D%209.8%20X%2048%20%3D470.4%20Miles)
The distance between AB is 470.4 Miles.
