At the scene of an accident, police can estimate how fast a driver was driving at the moment of a crash by measuring the length of the skid mark that is created by the car's sudden breaking. Use the formula s = 19.6kd, where s is the speed of the car at the moment of the crash, in miles per hour, k is the coefficient of kinetic friction, and d is the distance, in feet, of the skid mark. If police determine a skid mark is 128 feet on ice, find the speed of the car at the time of a crash.

Round your answer to two decimal places.

Answer = __ miles/hour

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

hi! i think the answer is 1/2 : )

i believe that the slope of the line is -5
