An accident investigator measured the skid marks of one of the vehicles involved in an accident. The length of the skid marks was 175ft. Use the formula s=24d‾‾‾‾√ to find the speed of the vehicle before the brakes were applied. Round your answer to the nearest tenth.

9514 1404 393

  64.8 mph

Step-by-step explanation:

We assume your formula is intended to be ...

(In plain text, this could be written √(24d), with parentheses indicating the contents of the radical.)

Filling in the given value of d, we find s to be ...

  s = √(24·175) = √4200 ≈ 64.8

The speed of the vehicle was about 64.8 miles per hour.

the answer is  

a.

4,624π mm2

step-by-step explanation:

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
