Question

My calculator died & I don't have a new one yet. Would someone please solve this for me. Thanks!! 1.3√ 160 = ____

Answer 1

google it lol

Answer 2

what factors of 160 are perfect squares?

Answer 3

I tried to Google it no luck. Even tried to find an online root calculator... it didn't except the decimal place...wanted Whole number

Answer 4

Oh come pls....its been almost 30 yrs since school

Answer 5

so you simply need the whole number of this thing?

Answer 6

it was 20 yrs for me lol

Answer 7

Its part of a formula for calculating the DPN for a sailboat. For racing. its used for multiple class races to even out

Answer 8

1.3 * sqrt(160 is what google will accept as the equation)

Answer 9

it is 1.3 root of the Sail Area. which is 16o sq-ft

Answer 10

oh

Answer 11

1.3 * sqrt(160) that is

Answer 12

I enterd the sqrt symbol
Thanks!!!

Answer 13

1.3 * sqrt(160) = 16.4438438

Answer 14

1.3 * sqrt(160) = 16.4438438 from the google :)

Answer 15

so 1.3√160= 16.44

Answer 16

Thanks for the help!!

Answer 17

youre welcome:)

Answer 18

Its 16.44..... All the Best :D

Answer 19

OK......thanks! but I think that is wrong...... Will someone with a good old fashioned HP Reverse polish notaion calculator check this for me. I think it is actualy:
1.3rd root of 160 = 49.5994556
1.3 * sqrt(160) = 16.4438438 is really saying 1.3 times the square root of 160 which is like 12.65, so 12.65 x 1.3 = 16.44

OK so after 30 yrs I may not remember everything I learned in HS, but I do know enough to check alternate sources, and I do have common sense.

Thanks for the help!

Answer 20

OK I guess no one on here right now prob even knows what I'm talking about when I say an HP Reverse polish notaion eh? Well its simple a term we used in the 90's for the Hewlet Packard high end calclators where you input in rverse of standard calculators.

Answer 21

you think its 1.3 as the root to the radical instead of a square root?

Answer 22

yes!
1.3root of 160

Answer 23

1.3√160

Answer 24

not 1.3 x √160

Answer 25

1' 3/10 = 13/10..

160^(10/13) is the answer to that one then

Answer 26

huh?

Answer 27

160^(10 / 13) = 49.6

Answer 28

radicals are fractional exponents

Answer 29

yes
1.3rd root of 160 = 49.5994556

Answer 30

\[\sqrt[a]{b} = b^{1/a}\]

Answer 31

now you get the medal.
Thanks! for confirming the first answers given were erronious.
Have a great day!!

Answer 32

\[\sqrt[5]{12^2} = 12^{2/5}\]

Answer 33

:) youre welcome

Answer 34

\[\sqrt[1.3]{160}=\sqrt[13/10]{160}=160^{\frac{1}{13/10}}=160^{10/13}\]

Answer 35

but what is (DPN) if (DPN)=A+[B(DR)]

DR=18.923
and A,B are Linear Regression Coefficients

Answer 36

yipes!!.... what math you in that has that?

Answer 37

or does the A & B require a data set to determine the answer....been to long since Statistics 103

Answer 38

I'm 20 yrs past College

Answer 49

Answer 50

lol no...it was a K-mart special...but a decent brand name..don't remember exactly..something like texas instruments or equiv. Couldn't afford an HP @ $300 while working way thru college. but it worked good enough to get me by with decent grades

Answer 51

It even had most of the mid to high level Statistics functions so it saved my butt in Statistics..it came with a little instruction booklet on how to use it and it was very detailed on how the formulas worked...like a little cheat sheet....got A's in Stats cause of it.

Answer 52

You'll have fun in Statistics..not as boring or hard as some make it look. Just remember...no matter how many times you flip a coin and it comes up heads, the odds it will be heads on the next flip is stil 50%....Statistics Trick ??? some instructors like to use.
