Slope of blue using their 2 points is 4/6 or 2/3
slope of green using their points is 2/3 which is the same as the other triangle.
4/6 = 2/3. and this is true, the slopes are equal
Answer:
C. E is the same distance from A and B.
Step-by-step explanation:
Line CD is a perpendicular that divides segment AB into two equal parts as it intersects segment AB at point E.
This divides AB into AE and EB.
Point E is the middle of A and B. Therefore, E will be the same distance from A and from B.
That is, AE = EB.
Therefore, the statement that is true is: C. E is the same distance from A and B.
Answer:
L = s^2/(30.25Cd)
Step-by-step explanation:
In accident investigation, the speed of a vehicle can be estimated using a polynomial function that relates speed (s) to the length of skid marks (L). The drag coefficient Cd will depend on the condition of the road surface and tires, but might be expected to be between 0.7 and 0.8.
If the skid marks end in a collision, the length of the marks that might have been made can be estimated using this formula, then that length added to the actual length of marks to estimate the original speed. The speed at the point of collision can be estimated by the damage caused, and/or the movement created.
In the above formula, length is in feet, and speed is in miles per hour.
