Answer 9

Did you read the problem, carefully, 2 or 3 or 7 times, and carefully jot down what you know and what you are trying to find? :)

You have 3 heights: 200, 400 and 600 ft.

You are given a formula that gives you the wire length (I'll call it w), depending on the height, h.

\(\Large w=\sqrt{h^2+(0.55h)^2}\)

So, plug in each h to the formula, and get each w.

Then it wants to know the minimum wire length needed is you attach THREE wires at EACH height.

so once you have the wire length for each height, you multiply each one by 3, and then add them all up, e.g.:

\(\Large 3\cdot w_1+3\cdot w_2+3\cdot w_3\)

Answer 10

I feel stupid, THANK YOU!!! That is..actually pretty easy, thank you. wow. Thank you again, you just make it easy for me and I think I love you okay? Thank you!!!@DebbieG

Answer 11

lol it's good to be loved. :) happy to help! :)

Answer 12

So, the answer is 2,188,200 ? Is that right? @DebbieG

Answer 13

no that's waaaaaayyyy too big. Did you remember to take the square root?

Answer 14

I was thinking the same thing lol, and square root? at what part?

Answer 15

OOHHH, YOU MEAN SQUARE ROOT THE WHOLE THING?!! I'M SORRY, I THINK I GOT WHAT YOU MEAN!! ^^

Answer 16

Well, not the "whole thing", but the formula for the individual wire lengths IS a square root. So you need the sq root for each individual wire length. Just follow the formula... plug & chug!! lol :)

Answer 17

OHHHH, each of the heights with the e length together then square root them then times by three and added it all together, is that right?

Answer 18

im sorry for taking your time T^T

Answer 19

Use this formula:

\(\Large w=\sqrt{h^2+(0.55h)^2}\)

do it for each of the 3 heights. Enter it carefully on your calculator... and just get the wire length for each height.

Add them together. then multiply by 3.

(Alternatively, multiply each by 3 and then add those all together... but probably less work to add and then multiply, rather than vice versa :)

Answer 20

I got the same answer. :(

Answer 21

the heights after using the formula,
200 = 52,100
400 = 208,400
600 = 468,900
is this right, first?

Answer 22

what heights are you talking about?? lol.... you're GIVEN height, you need to use that as h in the formula to get the wire length.

For h=200:

\(\Large w=\sqrt{200^2+(0.55\cdot 200)^2}=\sqrt{52100}\approx228.25\)

OK, now I see where you got the 52100 above.... and your others are correct too.

But then TAKE THE SQ ROOT. :) THEN add. THEN multiply by 3.

Answer 23

Your final answer should be under10,000.... not over 2,000,000. :)

Answer 24

ok, I think I got it, give me a sec to get this done! *^*

Answer 25

4,108.53 ????!!! IS THAT RIGHT??? :D
