Law enforcement: a police accident investigator can use the formula s=25l−−−√ to estimate the speed s of a car in miles per hour based on the length l in feet of the skid marks it left. how fast was a car traveling that left skid marks 105 feet long?

The speed of the car traveling was 45.8 miles/hour

Step-by-step explanation:

* Lets explain how to solve the problem

- A police accident investigator can use the formula S = 2√(5L) to

 estimate the speed S of a car in miles per hour based on the length

 L in feet of the skid marks it left

- To calculate the speed of a car traveling that left skid marks 105 feet

 long substitute L by 105

∵ S = 2√(5L)

∵ L = 105 feet

∴ S = 2√(5 × 105) = 2√(525)

∴ S = 45.8 miles/hour

* The speed of the car traveling that left skid marks 105 feet long

  was 45.8 miles/hour

answer: h

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
