Police can estimate the speed of a vehicle before the brakes are applied using the formula 0.75d=(s^2)/(30.25) where s is the speed in miles per hour and d is the length of the vehicle’s skid marks. what was the approximate speed of a vehicle that left a skid mark measuring 150 feet

About 58 miles per hour

Step-by-step explanation:

Given: Police can estimate the speed of a vehicle before the brakes are applied using the formula :-

, where s is the speed in miles per hour and d is the length of the vehicle’s skid marks (feet).

Now, to find  the approximate speed of a vehicle that left a skid mark measuring 150 feet, substitute d= 150 in the above formula we get

Hence, the approximate speed of a vehicle that left a skid mark measuring 150 feet = 58 miles per hour  .

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
