Answer 5

\[2\sqrt{5(105)}?\]

Answer 6

Yes @Astrophysics

Answer 7

Ok so what have you tried?

Answer 8

I don't know how to solve big square roots really. But I need this now :( @Astrophysics

Answer 9

\[2\sqrt{525}\] maybe that's easier, just keep simplifying that

Answer 10

Okay I got 10 times sqrt21 @Astrophysics

Answer 11

Yes! Exactly

Answer 12

That's the answer ?

Answer 13

Yup :)

Answer 14

Okay well I'm solving this problem LAW ENFORCEMENT:  A police accident investigator can use the formula S25L 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? And I have to round the answer to the nearest mph @ Astrophysics

Answer 15

@Astrophysics

Answer 16

What is S25L

Answer 17

S=2sqrt5l

Answer 18

Oooh \[S = 2\sqrt{5L}\]

Answer 19

Yes

Answer 20

I need this answer in the next 3 minutes :(

Answer 21

So S is your speed and L is your length this is exactly the same as your problem above

Answer 22

plug L = 105

Answer 23

I guess you don't have to convert any units either ft into miles or what ever does look like it

Answer 24

so that's the answer 10 times sqrt ?

Answer 25

Sqrt21 ? So there is no rounding to the nearest mph

Answer 26

Then put it in decimals if it's asking in that

Answer 27

What would it be

Answer 28

Use a calculator..

Answer 29

One minute left :(

Answer 30

I got 46

Answer 31
