Speed = Distance ÷ Time
Distance = 2797.2
Time = 0.15
2797.2 / 0.15 = 18,648
Speed = 18,648
If you use a proportion, you'll get:
Then, you use cross products:
Then, you algebraically solve x:
The answer is 5/3 inches , or 1 5/13 inches, or 1.6 repeating.
Answer:
the last one
Step-by-step explanation:
Answer:
Vector equation:
Parametric equations:
Step-by-step explanation:
The line is parallel to the vector 3i + 2j − k.
So the vector of this line is a multiple of this vector, so i will use 6i + 4j - 2k.
The line goes through the point (4, 2.1, 3.1).
So the parametric equations are:
The vector equation is:
